Mapping

Frederik Ramm tells the talk mailing list about a large redaction of names and administrative boundaries in North Korea following a request by the copyright owner, 38north. He also warns not to use Wikipedia or Wikidata as a source for restoring these names, as we don’t know whether their contributors obtained the data from a suitable source.
Robert Whittaker announced two new tools to improve OSM data in UK only: Ghosts and survey me!.

Community

Darafei Praliaskouski who sponsored the tile rendering server- vial, since 2016, seeks for someone interested in sponsoring this server, because he can no longer afford it.
Reddit user jongeheer asks the OSM community for input on an open world game pack addition for GTA, he’s creating based on OSM data. See the demo.
"More than 75,000 schools were imported into Peru", dannykath wrote in her OSM diary about the process of importing the schools in Peru and how it benefits the community.
Researchers from the GIScience Heidelberg group published a paper in the open source journal Open Geospatial Data, Software and Standards describing an IT infrastructure that can be used to collect and evaluate data about the OSM project.
Besides classical data sources such as the Planet OSM, the OSM Wiki, etc., other more or less OSM-related data, such as OSM Stats and Natural Earth is also included. The result is various data sets that were published in a standard container format.

Various visualizations of the acquired data are available:
- Geographical visualization of changesets depending on time
- Graphic of the most common English words in the tag descriptions in the OSM wiki
- Animation of the development of OSM tags over time
- Presentation of the correlation between first use of an OSM tag and first documentation of the tag in the OSM Wiki
- Visualization of daily activity in OSM
This data and the presentations are intended to provide a more comprehensive insight into the OSM world that has been possible in previous studies, which focused more closely on either social aspects or the evaluation of data.

OpenStreetMap Foundation

The minutes of the OSMF board meeting on May 24th have been published.

Stefan Keller tweets some preliminary results of his work on identifying "Areas of Interest" using OSM data, which he will report in the academic track at SotM-18.

Humanitarian OSM

Researcher of the Harvard T.H. Chan School of Public Health published a paper in the New England Journal of Medicine examining the number of victims of the Hurricane Maria in Puerto Rico in September 2017. According to official, but controversial information, the hurricane killed 64 people.
The researchers selected around 100 out of the 900 barrios in Puerto Rico, which are small administrative units with an average of less than 5000 inhabitants. For the sample of households, the authors randomly identified 35 buildings from the buildings on an OSM map in each of the approximately 100 barrios. The data for the selected buildings were downloaded from the Overpass API, the centroids were calculated and converted into Geospatial PDF files. The files along with an OSM base map were copied to the Samsung Tab A 7 tablets of the on-site interviewer.

Based on the surveyed households’ data, researchers estimate that 62% or 4,645 more people died in the post-hurricane period than in the same period in the previous year. For the researchers, it is likely that the actual number is higher, as their values are affected by the survivor bias.
Following the mapping of Hidroituango dam in Colombia, previously marked as high-risk for flooding, OSM Colombia asks experienced mappers to start validate the new data.

Maps

Netzwolf announces (automatic translation) in the German OSM forum to disable the data updates for historic.place and is looking for someone to take over the data supply for the historic.place in his place.
Railway platforms with covered=yes are no longer rendered and the first group of mappers is starting to remove this tag. This could be seen as mapping for the renderer. The word covered can be understood in different ways, so it was not a good choice for a tag to begin with. Maybe we will understand it as: you stand under something, out of sun and rain. The wiki apparently describes it as: it’s under another object or underground and can’t be seen from the air.

switch2OSM

The team behind OpenMapTiles launched a map hosting called MapTiler Cloud with weekly updated OSM data, customize tool and hosting for own geodata. The free plan is available also for open-source and open-data community project websites.

Licences

The Italian city of Bologna has publicly released a TMS with aerial imagery of the city, for the first time by default with an addendum to the CC BY 4.0 which explicitly refers to OpenStreetMap (English version at the bottom).

Software

The French company Magellium annouces on talk-Fr the magOSM service to access thematic OpenStreetMap datasets as WMS/WFS services available for metropolitan France. A Web map is available here for download. Source code will be opened in the next weeks.
HeiGIT demonstrated how to use the OSM History Analytics platform ohsome for OSM Street Network Topology Analysis and Disaster Activation Monitoring ISCRAM paper.

Programming

Uber released a new geographic visualization toolbox under the MIT license. The software is meant to help Uber gain insights from the combination of map data with POIs and millions of GPS points. kepler.gl is a web application for large amounts of data. It is based on the visualization solution deck.gl, also from Uber. It is meant as an improvement over the tool chain QGIS, Carto and Mapbox Studio and it makes use of Javascript with React, D3.js, and Three.js for visualization.
Microsoft aquires GitHub for US$ 7.5 billion in stock.

Releases

Version 3.0 of OsmAnd is released. Some of the improvements include:
- integration of travel guides from Wikivoyage.org

Did you know …

… that JOSM’s PT_Assistant plugin now comes with a new double split map mode, which makes it easy to add bridge, tunnel , traffic_calming=table and bus_bay? Everything that involves splitting a way at 2 nodes and assigning tags to the middle part. Polyglot describes this new functionality – added by Biswesh Mohapatra as part of his GSoC project – on the wiki.

OSM in the media

Following the Google Maps pricing policy change, « Le Monde » published an interview with Christian Quest (spokesman for the French OSM local chapter). Open alternatives like OSM are needed more than ever.
The Tagesspiegel shows (automatic translation) where new cycle paths are planned in Berlin based on OSM.

Other “geo” things

Mapping

Bryan Housel, developer of iD, explained on the tagging mailing list why he will not support the transit:lanes tag on ways. It may be possible to support the mapping variant based on relations instead.
A post about the tagging of grass provoked a huge discussion on the tagging mailing list. The title of the post, ‘The endless debate about “landcover” as a top-level tag’ seems quite apt.
On the Talk-GB mailing list the project MapThePaths was announced. MapThePaths is intended to improve the completeness of legal rights of way and permissive paths in England and Wales in OSM by visualizing missing entries. At the moment it is a pure viewer, but the creator plans to add an edit function.
The aftermath of an anonymous edit to alter the names of subway stations that also connect to surface lines in Berlin provoked some discussion on the German forum (automatic translation) about how stations should be named. This led to a discussion about tagging in complex junction stations.

Community

Heikki Vesanto created a presentation for OSGeo Ireland, that shows the evolution of OSM there. He published a guide for creating your own animations with Python, PostgreSQL, osmium-tools and QGIS on his blog.
On the Talk-US mailing list, a common discussion about an import in George’s County, Maryland became an interesting conversation about the use of Slack or real-time communication tools in general, which also encouraged participants outside the US to join. OSM US already uses Slack, which is not liked by everyone.

Imports

The mapper johnparis announces a bulk edit on the import mailing list from bus stops in Paris. He would like to supplement certain characteristics (Zone, Stop-ID and Ref) of Île-de-France Mobilités, formerly STIF (Syndicat des Transports d’Île-de-France).

OpenStreetMap Foundation

The OSMF board accepted a circular resolution to publish the preliminary version of the new OSMF Privacy Policy which has been worked out by the License Working Group.
The minutes of the State of the Map Working Group meeting of May 27th is online.

The international State of the Map 2018 conference takes place in Milan, Italy from July 28th to the 30th. The community ticket costs EUR 120.

Humanitarian OSM

Pierre Béland published stats of the OSM-RDC response to the Ebola outbreak with more than 800 remote contributors and 1.4 million objects edited since May 8th. NGOs and local organizations have also added POIs to the map and organized a mapathon for the local actors to revise and complete the map.
On the HOT mailing list, Remígio Chilaule has presented a short video that shows the mapping activities in Mafala, Mozambique.
HOT advertises a job for a paid part-time PR manager.
OpenStreetMap-RDC starts the #OpenCitiesKinshasa new mapping project and requests help from the global OSM Community to map dense neighbourhoods of Kinshasa prone to floods and cholera outbreak. This will support the local OSM contributors which are trained actually for field data collection and Drone missions. These actions are part of a partnership with the World Bank GFDRR, OSFAC and Potentiel3.0 to map vulnerable neighbourhoods of Kinshasa in the context of the “Open Cities Africa” project.
John Whelan reports on the HOT list about duplicate tasks created in the HOT Tasking Manager and creation of duplicate buildings. For some, mapathon organizers should assure training and validation of their participants and inform the coordinators of the humanitarian response of their actions. This OSM response to the Ebola outbreak is coordinated by OSM-RDC with the DRC Government, the UN Agencies and NGOs in the north of DRC.

switch2OSM

CPSolver presented his web page www.newsherenow.com on Reddit. It offers news particular to a neighbourhood.
Google Maps currently disallows access without an API key, as announced. This caused an inrush of requests on the OpenStreetMap Foundation Nominatim server.

70 key figures of the Internet warn about the new EU Copyright Directive in an open letter (PDF), which will be voted by the EU Parliament’s Committee on Legal Affairs on June 20th. The policy forces Internet platforms to automatically check uploaded content for copyright infringements. Julia Reda, MP of the German Pirate Party, wrote in her blog that there is a narrow majority in favour of the directive and asks to call MPs on the phone.
More than 100 Members of the European Parliament fear that the Europe wide introduction of an ancillary copyright law based on the existing German model could lead to a “link tax” and reject it in a public statement. Spiegel Online, as one of the largest German news website, already has experience with the law. In a comment, it wrote “Rarely was a law so dysfunctional…”

Software

Simon Poole reports on the Talk mailing list that the upcoming version 11 of the Android editor Vespucci will allow the integration of GeoJSON as a layer. The beta of the version can be installed via Google Play and from GitHub.
Wikimedia announced its new geocoding extension for CiviCRM, that uses OSM as default geodata provider.
Cosmogony is a new open source tool designed for easy extraction of boundary data. A dashboard provides a plausibility check of the boundary data in OSM and a hierarchical exploration is possible directly from the map. The data download feature has not been implemented yet. Similar services are mentioned on GitHub.

Programming

OSM Buildings published their privacy policy and a few updates on how to use their services.

Did you know …

.. that the mapper Lübeck created a map showing the locations of available defibrillators? Hopefully, you’ll never need this map.

OSM in the media

Glyn Moody wrote on linuxjournal.com that OpenStreetMap should be “a priority for the open source community”. He addresses Serge Wroclawski’s articles from 2014 and 2018 and concludes that OSM “has the potential to provide ambitious coders with the scope to make their mark in a new field of interest to billions of users.” In his opinion, it is necessary to create more software tools (e.g. Waze) to counter the overpowering market companion. He suggests a collaboration with financially strong open source organisations, such as Mozilla Foundation and Canonical.

Other “geo” things

MachinePix tweeted a video by Dom Ricciobene, featuring a CNC machine sculpting a mountain landscape on a layered wood block.
For the friends of Riesling, there is now a historical map available. It belongs to a whole series of historical maps, which is operated by the “Database of Cultural Heritage in the Trier Region”. As the person in charge confirmed on Twitter, the wine map can be used as WMS for OSM.
Grough magazine reports that Nigel Clifford has not renewed his contract as CEO of the British Ordnance Survey. This increases speculation regarding the lack of an announcement from the Geospatial Commission in May.
Since the 1930s, some 35 local volunteers have measured the spread and retreat of Icelandic glaciers at 64 measuring points using measuring tapes. The Atlantic reports on the project and why satellite based remote sensing techniques like the NASA satellite Terra cannot completely replace it.
Heise reported on two new JavaScript frameworks: MusicKit and MapKit JS from Apple. With MapKit JS, you can integrate interactive maps with overlays and controls, including routing services, on your own website. An API key is required for use. 250,000 instances with 25,000 service calls per day are free. A sample implementation has been published by Apple on GitHub.
Annette M. Kim warns about the potential inaccuracy of automatic feature detection from satellite images: informal settlements at the fringes of large cities may not be classified as urban areas, and would then be overlooked by city management. Only a combination of remote processing and ground checks can make sure that data available to city planners reflect reality.
Christoph Hormann writes about news on open satellite images in his blog. Topics include the increased image recording volume of the Sentinel satellites, which is achieved by an optical data link, the new report on data access to the Copernicus programme, to which the Sentinel satellites belong, and current developments in the US Landsat programme, which has been running since 1972.
There’s one spot in the world right now, where the sun is exactly overhead, and it’s this one. Unfortunately, we are not aware of the website that shows the place where the sun is at its nadir.

FIFA World Cup 2018 Stadiums in Russia ¹ | © Harry Wood © map data OpenStreetMap contributors

Mapping

On the tagging mailing list there was a discussion on whether amenity=shelter implies a building=yes tag. Judging from the answers, the topic is more complex than expected.
The OSM US Camera lending program is so popular that the goal needed to keep the camera had to be increased to 1 million OSC contributions, in order to ensure sustainability of the program. This will only affect new applicants.
[1] After Harry Wood featured the FIFA World Cup stadiums on wiki.osm.org as "photo of the week", ШТОСМ studied the maps and imagery for each of them and explains the reasons behind sub-par representation of these stadiums on OSM. Turns out there was no project to map any of these and there is still no recent imagery for the cities. The author points out that OSM still "won" by being used in MAPS.ME, which is the official partner of Rostourism.
Mapbox discontinues its support of their navigation data map.
Norgeibilder is the best available imagery for Norway, and the OSM community obtained permission to use it for mapping. With the latest release of iD the new orthophoto layer is now the default in iD, via the Editor Layer Index. Laser imagery (both DSM and DTM) is also available for the whole country, also through the ELI.
Mapbox has released 184,000 possible turn restrictions for more than 35,000 intersections in 23 cities in the USA. The restrictions can be viewed on a map (takes time to load). The restrictions should be double checked before entering them into OSM.

Community

OSM Belgium has named Matšeliso Thobei (OSM tshedy) from Maseru in Lesotho as Mapper of the month. Matšeliso is currently studying spatial planning in Ireland and has mapped extensively during her 3 years at OSM. In the interview she tells how she came to OSM, explains her motivation and her background.
The first of the Top Ten Tasks, a reporting function and complaint management system for openstreetmap.org, has been in use since June 16. Users, map notes (both by mail to the DWG) and spam diary entries (message in IRC channel #osm-dev) can now be reported in the browser with a few mouse clicks.
nyampire published a blog post about Shinsyu University of International’s switch to OSM. SUI is a fake university and famous for pranks in Japan. As SUI wrote in the html source "In order to avoid harm to OSM" they added their "university" only to a local instance of OSM data.

Events

The SotM Latin America 2018 will take place on September 24th in Buenos Aires. Proposals can be submitted until August 25.
Mappy published its report of SotM-FR 2018. The conference covered many topics, including pedestrian, cyclist and automotive navigation, public transport, humanitarian mapping, tools for mapping and a lot of new ideas.

Education

Víctor Olaya presented his book "Introduction to GIS", available under CC-BY license. You can find it on GitHub.

Maps

Richard Fairhurst shows on Twitter the differences due to the new clustering of bicycle parking spaces on cycle.travel.
Last week’s defibrillator map is – as some readers have noted – not updated. Therefore we would like to draw your attention to two alternatives today: emergency-map by wambacher and defibrillators in Austria.
Christoph Hormann continues his series of suggested improvements to the rendering of water related objects. After his blogpost about waterbodies and fords "Water under the bridge" he follows up with a new post "The way of the water" with suggestions on how to improve the rendering of water barriers i.e. dams, lock gates and weirs as well as water sources, namely fountains and springs. Here is an example implementation that he published on GitHub.

The EU Parliament’s Legal Affairs Committee has endorsed the new EU Copyright Directive, which introduces an ancillary copyright for headlines and text excerpts as well as upload filters. The plenary will vote on it in the first week of July. Wikimedia Germany presents their view. On change.org you can sign a petition against the upload filters and ancillary copyright.

Software

The BBBike extract service now offers OpenStreetMap data extracts in GeoJSON format. The step follows the shutdown of all of Mapzen’s services, including the Metro extracts, where the GeoJSON download was an often used feature. GeoJSON is an open alternative to the proprietary ESRI-Shapefiles.
Mapbox announced the release of RobotSat. While the OSM blog post highlights the feature extraction from aerial and satellite images with "polygon recommendation" at the end, the announcement at mapbox.com also mentions tracking of deforestation, fires and landuse as well as measuring the impact of natural disasters and humanitarian crisis.
With the Robosat recognising multiple features based on the aerial and satellite images, this is a step towards using AI or machine learning for mapping, Christoph Hormann (imagico) points to his own blogpost and we also previously reported about the research paper that talks about issues related to the same.

Programming

The company Sentiance announced Loc2Vec, an AI product to predict human behaviour. The neural network consumes location data like tiles generated by customized OSM-Carto stylesheets and outputs semantic similarity between different locations. Very simple put, the system gets some intuition and can say which venue a person is more likely to visit based on a given inaccurate location.
In the OSM forum a user asks for data sources for city models. He is working on the project OpenGlobus.org that aims to become a JavaScript library that can display interactive 3D maps with map tiles, imagery, vector data, markers and 3D objects.
Biswesh Mohapatra wrote a blog post on his background, how he came to the Google Summer of Code 2018 and his experience about working on the JOSM PT_Assistant plugin.
Princi Vershwal wrote a blog post on her work on Vector Tiles for the iD Editor during the Google Summer of Code project. She prepared the implementation of data in .pbf (Protocolbuffer Binary Format) and .mvt (Mapbox Vector Tiles) format.

Releases

The current release state of the software around OSM can be found on wambacher’s software-wachtlist.
Version 0.9 of the OSM-C-Tools (Osmconvert, Osmupdate, Osmfilter) has been released.
Version 2.9.0 of the iD editor was released. Support for Bing Streetside 360-degree panoramic image layer was added among other features. A Microsoft employee explains on the GitHub pull request which usage of the imagery is permitted and which not.

OSM in the media

The Italian newspaper La Stampa publishes an article about the upcoming State of the Map in Milan.
Grab (the Uber of the East) has been sponsoring a number of mapathons in Myanmar, Indonesia, Philippines, and Singapore. Their latest effort in Malaysia, with 50 university students, has generated a number of articles in the press including this one on Behind the Wheel.

Other “geo” things

Nastya Parygina published an article about FOAM. It is intended to replace more traditional geospatial databases with blockchain technology. It claims to be decentralized, up-to-date due to economic incentives and technology agnostic and has trusted historical data due to blockchain technology with a higher accuracy compared to GPS. A white paper goes a little bit more into the details. With regards to OSM, the article wrote that FOAM will solve the issues of unverified edits and the vandalism in general.
An article on The Conversation discusses why we cannot always trust what we can see in satellite imagery.
Topi Tjukanov wrote an article about the database PostgreSQL with its PostGIS extension, targeting consumers of spatial data. However, the article is worth reading for anyone who wants an easy written explanation of what PostgreSQL and PostGIS are and why it is worth using them.
Xiaomi has launched the world’s first dual-frequency GNSS smartphone, bringing decimetre levels of accuracy to consumer grade equipment. The new GNSS chip BCM47755 used by Xiaomi is able to receive all currently available satellite positioning systems i.e. the European Galileo, the well known US based GPS, the Russian GLONASS, the Chinese Beidou and the Japanese system called QZSS.

Version 3.2 of QGIS, codename “Bonn” (where the 16th QGIS developers meeting took place in 2016), has been released on June 24th. A visual changelog was also published.

OSM in the media

The German IT newspaper “Netzwelt” published an article about the advantages of OSM over Google. The key argument, access to the raw data, was bolstered with an OSM-based study from a travel website about the greenest cities worldwide. (Hint: Reykjavík, Auckland and Bratislava are numbers 1 to 3)

Other “geo” things

As reported (automatic translation), Google is updating its data for Germany. Although they improved the cameras on their cars last year, there are no plans to update the Street View images as the German data protection law prevents it according to a statement from Google. Instead they are collecting data for an improvement of street names, road geometries and POI data.
The Swiss Federal Office of Topography is asking for help to georeference historical images of the country. Even if you can’t help, you may want to browse through over 50,000 historical images of Switzerland.
StreetCred, created partly due to the shutdown of Mapzen, is estimating that there are 1 billion POIs across the world. The company announced that they want to build a marketplace to buy POI data from users that collect the data and sell it to companies.

Mapping

With casinos as an example, Carlos Cámara started a discussion on the mailing list about the responsibility of OSM to render content on the map, that might be difficult from an ethical or social point of view.
Mateusz Konieczny proposes a mechanical edit to change FIXME=* to fixme=*. Both tags are in use, in a few cases on the same object with different values; however, the uppercase variant is less common and actually predates the lowercase one. The long discussion on Talk mailing list involves both the editing procedure and ways to prevent the uppercase variant to be used in the future.
Mateusz Konieczny asked the tagging mailing list about how to tag bakeries not selling bread or other bread-like products.
As you probably know Germans map a lot, but did you know that they delete a lot, too? A mapper complained that (among other tags) his bicycle=no on highway=footway was deleted without any notice. A discussion of reasons for or against adding default values was started but ended without an agreement.
Map Kibera moved to map Mbooni, a second ward in Makueni County, Kenya. They produced a video that shows the challenges they had to face, and the involvement of local representatives and volunteers.

Humanitarian OSM

Satoshi IIDA asks for mappers and validators after the Osaka earthquake. This is the task.
Many mappers are surprised when they stumble onto the low-quality mapping in Africa or Asia. This often relates to HOT mapping activity. Jean-Marc Liotier has asked “Why the HOT obsession with low-quality buildings in Africa?”. (picture one, picture two). Another mapper pointed out that buildings serve as proxy for the local population. The question why low quality buildings or thousands of duplicate buildings dumped to OSM rather than counted somewhere else is still not answered. To address the known issues a duplicate building validator was recently added to HOTOSM fork of OSM Lint, a validator to identify geometry and metadata problems.
Using lessons learnt in health mapping in Dar es Salaam, a team from HOT Tanzania have been working on the latest Data Zetu project in Mbyea, which is in the southwest of Tanzania. The team have been training and working with the local community in mapping local administrative boundaries and collecting data about access to health services.
In HOTOSM News there is a writeup of new hardware demonstrated at the recent Amazon Web Services Public Sector Summit. This box is a fully offline, 100TB storage, field-deployable version of OpenAerialMap and Portable OpenStreetMap for offline mapping for disaster areas.

Warin, who noticed a new mapper trying to map a golf course, complained to the tagging mailing list about the current wiki page describing how to map a golf course. That triggered a lengthy discussion on the mailing list, where we discovered that it makes sense to consider even the grass height in recognising the tee area.
Leo Gaspard would like the landuse=highway tag to be used more often as he wants road areas to be tagged along with their surfaces. However, as noted during the conversation, the widely used area:highway=* includes an optional surface tag already.
Danilo reported on the Swiss mailing list his experience with creating his own aerial images with a paraglider. He mentioned the project opendronemap.org, a toolchain for processing aerial imagery. His example result (large file) looks promising.
How many traffic light nodes should be added for complex intersections? This question was raised in the German forum. The conclusion was to tag traffic lights for pedestrians with highway=crossing and crossing=traffic_signals to avoid multiple time penalties when routing cars over an intersection with multiple traffic lights. The possibility to add the direction of traffic lights was also mentioned.
The Open Knowledge Lab Karlsruhe has created a map that shows farm shops, market places and vending machines for food and milk in Austria, Germany, Switzerland and some neighbouring regions. They explain the map and future plans in the German forum . If you want to join the development or make your own map for your region, you can find the project on GitHub.
Warin61 has created a proposal for ephemeral water, i.e. water that is only present for short duration.

The voting for the OSM Awards ends on July 26th. Please vote if you have not done so already.
The media platform TriplePundit published a story about the benefits of collaborative problem-solving. It mentioned the well-known code creation and mapping efforts for disaster relief but also forward-looking development aid such as openRMS, an open source enterprise electronic medical record system platform for resource-constrained environments.
[1] Rixx published a blog post about the orientation of streets in European cities. He wrote a Python script, which
he made available on GitHub, which shows the direction that a city’s streets run in most often. He continues the work of Geoff Boeing who wrote a blog post "Comparing City Street Orientations" using his OSMnx Python library. In a description of OSMnx Christoph linked to a number of blog posts about OSMnx use cases ranging from figure-ground diagrams over isochrone maps to network-based spatial clustering.
Mapbox catches up with its own version and presented a slippy map with streets orientations. In a blog post they explained their implementation that is available at GitHub.
The company Uber uses OSM internally for fare calculations and to optimise driver and rider matching as they have explained in the forum. The team in Palo Alto will start fixing bugs found in OSM by Uber drivers in the Delhi region in India as a test. According to their forum post, they will share the profiles of the editors on Uber’s OSM page, will follow the Organised Editing Best Practices and Indian guidelines, and do not plan to make large-scale, machine-generated edits.

… of Pascal’s website Unmapped Places? The intention of this tool is to detect under-represented regions a.k.a. “unmapped” places in OpenStreetMap. Basically it checks whether a road can be found within 700 m around a place= tag or otherwise it will be flagged as unmapped.

Other “geo” things

The German blog beyong-print published a post about the start-up cartida that is offering art prints of maps based on OSM data in different styles and sizes. Currently they only ship to Germany, Austria, France, Netherlands, Belgium and Luxembourg but they plan to add more countries.
govtech.com, an online portal covering information technology’s role in state and local governments, reported that Google’s new API restrictions will have minimal impact on goverment bodies. From July 16 onwards, Google Maps requires an official API key and a valid credit card attached to the account in order to work. However, state and local governments prefer using paid products from ESRI, Mapbox and Boundless Spatial for their work.
The Mississippi’s Board of Licensure for Professional Engineers and Surveyors sued the company Vizaline, which provides banks with polygons on satellite images for use in granting loans. The Board says that it should be the state entity solely responsible for land surveying.
It is no secret that new edits do not always improve the data in OSM. A research study now provided some more insight. The conclusion was that the completeness and positional precision of features can be improved up to 14% if you take the history data of objects into account.
Mongabay, an online platform for environmental topics, published an article about MapHubs. MapHubs is a commercial platform storing maps and spatial data for viewing and analyzing. Paying users can use public and private data sets to create customised maps showing deforestation and generate time-lapse videos in "minihubs" called websites.
The website visualising data published the 53th episode of its "the little of visualisation design" series. The series focuses on small design choices and demonstrates with a sample project in each episode. Using an article from The Guardian, the website explains in the current episode the use of thumbnail map images that helps orientate the viewer.

Mapping

Ilya Zverev is proposing a lighter tagging scheme for public transport. In an email to the tagging mailing list, he notes a growing discomfort with the current scheme. The concepts behind these suggestions will be covered in his talk What’s up with the public transport at SotM in Milan.
Portuguese researchers have published a paper in the journal Hydrology on how data from OSM can be used to improve digital elevation models. They compared a DEM built from Shuttle Radar Topography Mission (SRTM 30) data combined with waterways from OSM, with a DEM from the British Ordnance Survey. They concluded that an improvement in the horizontal accuracy and a decrease in systematic errors is possible.
As SotM-US is being held in Detroit this year Mikel Maron is helping to make OpenStreetMap in the area better, starting with bike share docking stations. He wrote a diary post describing how he was confirming and improving the locations of bike share stations, that were already added in OSM, using open data along with aerial, Bing Streetside, Mapillary and OpenStreetCam imagery. In his comprehensive blog post he explains his workflow and what he has learned during this exercise.
Following feedback from a user of Microsoft’s Soundscape, an app aimed at providing spatial information to people with low vision, Microsoft asked for volunteers in the OSM forum to help improve the mapping of Montclair Plaza (Wikipedia, OSM.org), near Los Angeles.
The granularity of the values for the building attribute tag is causing misunderstandings. On the tagging mailing list the question of the difference between building=house and building=detached was raised. Apparently, there are different understandings depending on the region.

Paul Norman, member of the OSMF board, wrote an article for the Wikimedia mailing list about his experience and lessons learnt with creating a new style and vector tile schema for the WikiMedia foundation. Beside styling improvements, the style changes were to enhance the representation of disputed borders.
Penegal has opened several pull requests for the OSM Carto stylesheet to improve the readability of the base OSM map. He wants to increase text and shield distances for waterways, railways and roads.

switch2OSM

The French department Maine-et-Loire has switched (automatic translation) to OpenStreetMap. Like other professional clients, they had to adjust rapidly following the announcement in May of an enormous increase in the cost of Google Maps (free for them until now). The OSM ecosystem and the drastic increase of the quality of OpenStreetMap over the last few years facilitated the decision.
On der Apotheke a Polish company recently wrote about how and why they chose to change map providers for their website, following the recent pricing changes of Google Maps.

Software

The Critical Numbers webapp by GIScience Research Group, Heidelberg visualise in the form of a bar chart the percentage of OSM Tasks mapped and validated (data from the HOTOSM-Tasking-Manager API instance). Data can also be downloaded as GeoJSON for further processing in QGIS or other applications. The authors have created an extensive introduction with examples. Such quantitative analysis could take into account other variables such as the contributor’s OSM experience or topological data errors.
Notes in iD have arrived is the title of a blog post by Thomas Hervey. Notes in iD have long been desired by users and can now be tested in a preview version.
The geospatial company Boundless announced that it will be hosting a webinar on August 2nd focused on Boundless Offline Tile Server (BOTS), a lightweight, portable, offline, high-performance map tile server.

Programming

Maning Sambale writes about his experiments with RoboSat for feature detection from aerial imagery. He confirms that data cleaning and utilization of proper training sets are crucial for accurate results, and suggests using this procedure to facilitate remote mapping.
A large influx of spam in OSM notes with personal insults was reported (automatic translation) in the German forum. After discussions with the DWG and a block did not help to calm the situation, Frederik Ramm submitted a pull request that will stop anonymous comments in notes on OSM’s website if implemented.
Following her introduction after Anusha Singh was selected to join the Google Summer of Code working on the OSM Public Transport Editor, she has now provided an update on progress she has made so far.
Jennifer Cats wrote a diary post on how she identifies spam or other difficult labels (i.e. name=) using language processing techniques.

Releases

The version 4.13.0 of OSM’s carto stylesheet has been released. Changes include increased shield distance on roads and new icons for five shop types and three amenity types. The documentation has also received improvements. The full list of commits can be seen on GitHub.
According to a tweet from wambacher, there are new versions for the following OSM-related software available: Komoot Android, Leaflet 1.3.3, Magic Earth iOS 4.1.0 and several Mapbox GL products.
You can find these updates along with an almost endless list of OSM-related software and current versions in Wambacher’s software list.

Other “geo” things

Stéphane Péneau tweets his disappointment that Mapillary is still compressing images. He added examples of how the compression lowered the quality of the images.
SpringerOpen, part of the global academic publishing company Springer, made a Call for Papers for a planned publication with the title Special Issue: Open Source Geospatial Software as reported on the OSM-Science mailing list. Papers on Volunteered Geographic Information (VGI), Crowdsourcing and OpenStreetMap (OSM) are all invited as outlined on SpringerOpen’s website.
The Register reports on a paper from Microsoft, Virginia Tech and the University of Electronic Science and Technology of China. It describes how vehicles can be “hijacked” with a Raspberry Pi and a Software Defined Radio of the type HackRF One (175 US dollars). Technically, this is GPS spoofing, which is often used in military manoeuvres. To keep the vehicle on the road, routes were calculated using OSM data.
A Vietnamese online newspaper has published an article complaining about the appearance of the Paracel Islands on Facebook’s maps. Like many other island groups in the area, these have multiple sovereignty claims over them. According to the article the Vietnamese government will try and rectify this “mistake”. Facebook apparently stated that “all its maps were provided by third-party companies like OpenStreetMap and HERE Maps”. The OSMF’s position is clear – “The OpenStreetMap community operates under the ‘on the ground’ principle” and “you are free to make maps from our data leaving out or putting in what you need for harmony with your general usage, culture and legal system”. What organisations with different national audiences tend to do in a situation like this is to provide different maps for each, with the appropriate “alternative facts” presented to each audience (a Vietnamese user would see the islands as part of Vietnam; a Chinese one as part of China).

SotM 2018 Milan

[1] State of the Map, the global OpenStreetMap Conference, happened last weekend in Milan, Italy from the 28th to the 30th of July 2018. You can watch the recorded videos on their YouTube channel and find all the pictures here.
We wish to congratulate the winners of the OSM awards 2018:
- Sarah Hoffmann (Core Systems)
- Wikimedia Foundation Collaboration Team (Innovation)
- Christoph Hormann (Influential Writing)
- Matšeliso Thobei (OSM username Tshedy) (Greatness in Mapping)

- Natalia da Silveira Arruda (Latin America)
- Crowd2Map Tanzania (Africa)
- State of the Map Asia 2017 organising team (Asia) and
- Richard Fairhurst (Ulf Möller Memorial Award)
During SotM Milan Martijn van Exel announced the relaunch of ImproveOSM. This now brings together all of Telenav’s tools for the OSM community.
From SotM Milan 2018: an overview of the first day’s activities from various presentations.
On behalf of the Mapbox team at SotM, Jinal said how much they were looking forward to seeing people at in Milan. In case you did not find the time, or live in a part of the world far away from Italy, she gives a list of other OSM related conferences where you will be able to meet the team.
On the OSM blog Harry Wood says thanks to the visitors and organisers of the SotM in Milan. There are already unedited videos of the two main conference rooms linked from the article.
During SotM a Memorandum of Understanding between the OSGeo Foundation and Youthmappers was signed. The agreement proposes to establish a collaborative relationship in several areas such as research, education and conference participation.OSGeo is an organisation that promotes the adoption of open geospatial technology, Youthmappers is a university consortium of 120 campuses in 38 countries active in the humanitarian and development sector.
State of the Map 2019 will take place at Heidelberg University, Germany, from 21st to 23rd September.

About us

weeklyOSM is now published in Korean. Korean is spoken by about 80 million people, mainly in Korea but it is also an official language in two Chinese regions. OSM-related news can now be read in Japanese, Czech, English, Spanish, French, German and Korean. According to a Tweet from Geoffrey Kateregga we may welcome a Swahili version of our issue soon. Swahili is spoken by about 50 to 100 million people in Tanzania, Kenya, Uganda, Rwanda, Burundi, Mozambique and Congo. 고급협동조합 and Geoffrey are still looking for partners to help them. weeklyOSM is looking for a better flag to use for the Korean language in the WordPress plugin qTranslate.

Mapping

Rarely has a discussion in OSM escalated so quickly as it did following an email to the talk-us mailing list about unconnected lines that were supposed to become sidewalks.
jgon6 was dissatisfied that there was no convincing way to tag fairgrounds (showgrounds). A map note gave him a heads up and he looked into the issue again. He wrote an email to the tagging mailing list and published a dairy post, in which he laid out his extensive thoughts and findings about the different ways of tagging to get other people’s views on it.

Community

Researchers from the Politecnico di Milano investigated criticism of OSM around the unknown quality of data collected by unqualified mappers. In a journal paper they report on the comparison of the number and spatial accuracy of 1 million buildings in OSM and 2.8 million buildings in an authoritative dataset from the Lombardy region in Northern Italy. They concluded that at the 1:5000 scale the quality is at least comparable with the reference data. In terms of completeness OSM has 57% of the buildings found in the public dataset. The researchers also found that 9% of the buildings in OSM were not in the reference dataset.
Philipp Koster (HSR Rapperswil) published an OSM based Area of Interest (AOI) dataset for Switzerland. Google introduced the AOI concept (high activity areas shown as orange shaded areas on their maps) in 2016 but did not disclose the algorithms used to create it. Prof. Stefan Keller presented this work in the academic track at SotM.
In his blog “Maps Matter” SK53 wrote about how the completeness of data in OSM can be estimated without using external datasets for comparison. The question becomes particularly important when thinking about the generation of Areas-of-Interest, which requires POIs to be reasonably complete. His idea is that the number of POIs over time should develop similarly to Species Accumulation Curves (at first increasing slowly but then accelerating and finally leveling off ). The article details step by step his approach of investigating the question for shops in the UK using Overpass, Osmium and PostgreSQL. He concluded that there are still a lot of shops to be added, even in the best-mapped places. Some shop types, shop=supermarket and shop=doityourself, do show signs of slowdown. In terms of the number of distinct values forshop= he found the curve tailed off and suggests that the existing shop tags are sufficient to meet our tagging needs. Joost Schoope pointed out that a similar approach has already been used for roads.
The eighth edition of the Belgian Open Summer of Code project ended last week. It was bigger than ever and used OpenStreetMap heavily, as illustrated by Pieter Vander Vennet’s diary post.
We are looking forward to the results of the user profgreenington’s bachelor thesis. He reports in a diary post (automatic translation) that his topic is the generation of indoor maps, in digital as well as in paper form.
Richard Fairhurst wrote a forward-looking blog post about implementing vector tiles, placing this centre stage in a comprehensive overview of the OSM context. He recalled the very first days of OSM, summarised the current situation, noted the constantly repeated argument that OSM is a database not a map, made it clear why we are not and why we don’t want to be Google or Apple maps, touched on contributor motivation and diversity and brought it all together to argue for restylable vector tiles on openstreetmap.org as a tool to generate customised maps. The article also offers refreshingly calm words about machine learning/AI in the OSM environment and visual feedback on maps as a motivator for contributors.
Ilya Zverev supplemented Richard’s blog post on vector tiles. In his diary post he points out that the OSM carto developers are approaching the change to vector tiles only as a technical task, which he sees as a mistake. His point is that our style is overshadowing our product, i.e. geospatial data. He suggested that users should look elsewhere for nice-looking OSM maps and the OSM website should focus foremost on data and possibilities. He recommends that OSM delivers raw vector tiles coupled with an improved map builder including a style database containing hundreds of styles.

Imports

In a tweet Allan Walker points to his visualisation of the number of buildings in OSM compared to Microsoft’s building footprint dataset for the United States. As you can see, in number terms Microsoft is leading, by far, in all states except Massachusetts.

The news site Moneycontrol reports that Uber is working on a plan to move from Google maps to OSM. weeklyOSM has recently reported about Uber’s plan to contribute to OSM in the Delhi region in India.

Programming

The OSM wiki now supports templates written in the Lua scripting language. It is hoped that this will improve the performance and maintainability of frequently used, complex templates such as the language selection bar.

Releases

JOSM developers just published release #14066, that brings several bugfixes and improvements.

Did you know …

… the sources of help if you have questions with regard to OSM? You can ask your question in the OSM forum, on one of the mailing lists and at Q&A site help.openstreetmap.org. Unlike the forum or mailing lists, the site is not intended for discussions, but for factual questions for which there is ideally an objectively correct answer. If you want to help others with your OSM knowledge, take a look at the list of unanswered questions. Maybe you deserve a place in the points list?

OSM in the media

William Plummer of the French newspaper Le Figaro has analyzed the naming of streets in Paris with the help of OSM data. In addition to the birth years of the namesakes, the professions were also represented graphically.

Other “geo” things

The news agency Bloomberg reports that Mapbox claims to have a role in the future of ride-hailing and autonomous cars. With its customers Uber and its rival Lyft, Mapbox has already a foot in the door for the technology that is seen as the future of mobility.
The ESA has launched four additional Galileo-satellites using Ariane 5. The new satellites, which are expected to have a life span of 12 years, join their 22 peers in space. The Galileo system requires exactly 26 satellites for becoming fully operational. However, another four are still in maintenance mode and reserve satellites will have to be launched later for full coverage.
The website GIS Lounge reports that hydrologists from two US universities have developed a worldwide river and stream surface dataset. They used Landsat satellite imagery, field measurements from thousand of gauge stations and statistical models in its creation. The Creative Commons Attribution 4.0 licensed dataset, called Global River Widths from Landsat (GRWL) Database, is available for download.
The photographer Susana Vera (Reuters) visited the two last inhabitants of the old village of La Estrella in the very sparsely populated province of Teruel in northeastern Spain. The result was a photo gallery (Spiegel Online). The village, as well as others in the province, are suffering a rural exodus. Thirty years ago there were still 200 inhabitants living in La Estrella. Once a year the church is used by pilgrims. A sad chapter in the struggle for “survival” in the European province. The two old ones about themselves: “The idiots who stayed”. For the OSM community this means rethinking in place – tagging.

SotM 2018

Writing a report on SotM-18 in Milan was one of the requirements for scholarship winners. To date these have been filed by:
- arnalielsewhere from the Philippines
- Austin Zhu from China
- Kateregga1 from Uganda
Reports on the Milan State of the Map conference held at the end of July are coming in thick and fast. So far we have spotted detailed accounts from The ODI (GB), Klokan (OpenMapTiler) (CH), Ilya Zverev (RU) on his WhatOSM blog (automatic translation), Christoph Hormann with his German and English summary and the SotM team about the Sunday social event.
imagico wanted to add some points to the vector tile discussion, so he wrote a blog post. He dampens the euphoria by highlighting technical issues and pointing to the limited number of developers in OSM.
Ilya Zverev, Vladimir Elistratov, Timofey Subbotin, Daniil Kirsanov and Viktor Shcherb recorded an 83 minute podcast in Russian at the SotM in Milan summarising what they saw and learned during the conference. Ilya posted a short overview in his user diary and a link to the full transcript in English.

Mapping

Some national parks require the decontamination of footwear to stop the spread of contaminants. Voting has opened on a proposal for the tagging of footwear decontamination stations.

Community

No node, way or relation will be left behind. A property owner deleted ways in OSM as they were private roads and the owner had previously experienced unpleasant incidents with police involvement. After a long discussion in the changeset comments the delete was reverted and the ways in question were marked as private.
Chetan Gowda wrote an article describing how he used Mapolution to visualise the evolution of OSM in different countries. He explained how to install the required software on a Mac and described his workflow in his comprehensive post.
In a tweet Bertrand Billoud congratulated the Senegalese OSM community for having mapped the public transport network of the operator Dakar Dem Dikk in Dakar. According to an SotM France presentation, 11 parties collaborated to achieve the common goal.
The Mapbox blog carries an interview with Clifford Snow who explains how he is helping to map every road in Washington State. He describes the toolchain, source datasets and his motivation to provide as much help as he can to improve OSM in his home state.
Frederik Ramm points to a paper , published in the journal Big Data and Society, about technology development in OSM from a sociological point of view. The author says that lack of development in the data structures for more than 10 years is mainly caused by the “dominant position of few project members who are able to change the software design“. In the only answer on the mailing list, John Whelan questions the need for change as described by the author of the paper.
Xamanu translated his article, originally published by the Austrian Scientific Exchange Service, in the osm.org user diaries explaining how the mapping for OSM at the end of the world in the Himalayas in the Tien Shan Mountains in Kyrgyzstan is carried out. Students of a nearby university used GPS, pen and paper and other old-school techniques in order to generate a map that helps local inhabitants with their basic needs, including the improvement of their water supply, which was the central theme there.

Updated maps of the region enabled the helpers to locate villages and provide medicine, food and warm clothes more efficiently.
Pierre Béland tweeted about the Ebola Outbreak Response tasks for north DR Congo and published on the OpenDataLabRDC Blog a Building Geometry analysis of task 4947. Topological analysis shows that only 3.5% of buildings have irregular forms (i.e. not 90 degrees or regular angles). This offers a different angle for validation / correction of buildings.
The Chronicle of Philanthropy published a podcast including a transcript, featuring Tyler Radford, HOT director, with the title “Nonprofit Creates Maps to Aid in Relief Efforts Around the World”.

Richard Fairhurst shares examples of small independent websites affected by changes in Google Maps pricing on Twitter.

Software

Terrestris, a German GIS company, points out on their blog that they developed GeoStyler, an online editor for OpenLayers and OGC SLD rendering styles together with Meggsimum.
Wille Marcel shared the recent and future improvements for OSMCha, a validation tool for OSM, in Milan at SotM 2018. The slides are available here and the video of the talk is on YouTube.

Programming

Ever walked in a city where lifts, funiculars, ferries or other mechanised infrastructure are essential to get around? Routing engines do not always support them. Guillaume Rischard discusses how they possibly could in his SotM talk in Milan.
Tom Chadwin made a QGIS plugin available on GitHub that exports your QGIS map to an OpenLayers/Leaflet webmap.
Thomas Hervey proposes a pull request to add a QA section in iD that will display issues such as those coming from KeepRight, an automatic data consistency check.
Nikolai Janakiev, who the regular reader of the weeklyOSM may already know due to his data science projects with OSM, Python and Blender, has written a guide that can help you if you want to load OSM data from the Overpass API into Python. The article covers the OSM data model briefly, an Overpass API introduction, the direct download in XML or JSON or the use of a wrapper and also a quick visualisation with matplotlib.
xamanu shared two articles about public transport on his user diary at osm.org.
In his first article he describes how they rewrote a tool that generates a GTFS file based on OSM data as they needed the data for the first proper bus map of a Central American city. You can find the tool at GitHub.
In his second article he explains how OSM public transport data were then made available to people’s smartphones in Nicaragua. As xamanu laid out they made the GTFS data available for different services and apps: transit.land , Navitia, Transportr and TransitApp.

Releases

Developers announce iD 2.10.0, which now handles OSM notes, the new Detach Node functionality, and a resizable photo viewer. See the full changelog for more details.

Did you know …

… the tool latest-changes? It provides a visualisation of map edits from yesterday, last week or the last month. You can find the source code on GitHub.
… the MapUganda.org project founded in 2012?
… openmaptiles.org? Petr Pridal and Jiri Komarek gave a presentation about the topic at SotM 2018 in Milan. The slides are available here.

Other “geo” things

Arjen Luijendijk and others present in Scientific Reports a global-scale assessment of the occurrence of sandy beaches and the rate at which their shorelines are changing. They used the global shoreline from the OpenStreetMap dataset of 2016 along with satellite imagery from Landsat and Sentinel.

The New York Times reports that people are relying on placenames found on Google Maps to the extent that they are replacing historical local names. This happens even when the Google names are typographical errors, or the result of SEO (search engine optimisation).
Vietnam has a new attraction, a very unusual footbridge with construction seemingly inspired by a fantasy movie. The bridge named Cầu Vàng (English: Golden Bridge) is 150 m long, with a spectacular view across the Ba Na Mountain chain all the way to the South China Sea. Geo.de has a report (automatic translation) about it. This region, which is a recreation area with many attractions, is unfortunately only sparsely mapped on OSM. On Bing and Esri aerial imagery quite a few features are easily identifiable.
According to an article at Route Fifty, a website targeting readers from local and state governments in the US, the government sector will increasingly use cloud-based mapping to assist residents and rescuers during disasters. Mapbox already partners with many government agencies in the data science sector. The available statistical data would be used to coordinate where to target aid.
At ESRI’s 38th annual user conference the company showed its updated dynamic ArcGIS Living Atlas of the World with new data and capabilities. New features include the visualisation of historical, forecasting, and real-time data such as temperatures or global population growth models. Other new features are the OSM vector basemap and wayback imagery, allowing travel up to five years back in time.
As several media outlets have reported, and you may have already noticed, Google Maps is no longer flat and will reveal its sphericality if you zoom out far enough.
StreetCred attempts to estimate the actual number of POIs, in a test subset of cities across the globe, by assuming that a POI can’t exist without a road that leads to it. With additional data, the prediction will become increasingly accurate, and will help identify areas where more mapping would be beneficial.
Joshua tested the Wahoo ELEMNT BOLT bicycle computer and he discovered that it violates the GPL and various other Open Source Licences.

About us

Wikimedia Germany wrote (automatic translation) an article about OSM and weeklyOSM in particular. It covers the history of both, OSM and our Weekly News, and some background information on what it means to operate a blog with 12,000 readers. As reported, weeklyOSM is now translated to Swahili and Korean, which was partly made possible thanks to a Wikimedia Foundation grant.

Mapping

On the tagging mailing list Frederik Ramm wondered whether place nodes for continents are useful. Even if they are it may not be possible to place them consistently, given that continents can be defined in different ways.
The discussion on the OSM talk mailing list that originally started with the question on whether highway=* + area=yes or area:highway=* should be preferred, soon expanded to questions about routing over areas, generalisation and as usual the documentation or the lack thereof in our Wiki.
Andy Mabbett raised the question "Slash, space, or spaced hyphen in multi-lingual names" on the tagging mailing list, pointing to the supposedly inconsistent wiki page. In fact, it merely documents different practices were adopted in distinct multilingual locations around the world.
The upload of historic county boundaries in the UK caused a long discussion on Talk-GB as to whether these objects should be in OSM or not. While there are many good arguments against intangible historic data, the discussion was not that clear in favour of the removal. The mapper who uploaded the changeset participated in the discussion and gave some background about his motivation.
The possible use of the Open Location Code system, also known as Plus Codes, within OSM has resulted in long and heated discussions on GitHub and the talk mailing list. The issue is scarcely a new topic for OSM.
Plus Codes, which are basically a transformation of latitude and longitude coordinates into a more memorable format. Like the proprietary scheme What3Words they offer better geolocation in places, such as many countries in Africa, where most buildings lack addresses.

The key dispute is whether they should be implemented on OSM and if so where: as tag/value pairs, computed on the client side, or provided by geocoders.

As a response to the recent discussion, Frederik Ramm wrote a FAQ styled blog post covering the most important points to which he added social arguments as well. Christoph Hormann and Ilya Zveryev (automatic translation) provide two different perspectives on their blogs.
The Korean OSM community changed all keys containing ko_rm to the BCP 47 standard compliant ko-Latn. This change has been discussed for the first time in 2015 on the talk-ko mailing-list where Thierry Bézecourt mentioned the -Latn tag. In 2017, users Nrimbo and Artemis64 both proposed a mass edit and the community agreed on it each time. Other countries still use the xx_rm scheme, neighbouring Japan for example.
The voting for the proposed feature evacuation routes is under way. Evacuation routes intend to aid people’s evacuation away from natural desasters like hurricanes or tsunamis and are typically signed with a round, blue evacuation route sign, at least in the US.
According to a tweet from the JOSM developers, Microsoft has fixed their browser Edge, such that it is not treating content from local loopback as mixed content anymore, which means that "Edit with JOSM" now works, as it has for years already in other browsers.

Community

The 14th birthday of OpenStreetMap was celebrated around the world!
Good news from Gregory Marler on Twitter: the first SOTM videos of individual sessions are now uploaded to the SOTM Youtube channel. They are working on uploading them all and created a playlist for you. You are invited to add transcriptions and translations as explained here.
BBC radio features Fatima Alher and OpenStreetMap Niger who are mapping the flood plains in Niger for Flood Resilience.
The demolition of slums to create space for other projects were often without any consequences as no one could tell how many people were affected. The lack of information is often a problem as it makes the demand for compensation hard or impossible or it may even prevent the demolition in the first place. Slum mapping has become popular as it’s harder to destroy what is documented.The article at the BRIGHT Magazine explains the issues of unmapped places like the slums in Kenya but also the help that projects like Map Kibera can provide.
United States ambassador to Turkmenistan, Allan Mustard (OSM apm-wa), has been chosen as Mapper of the Month by OSM Belgium. Allan described his biggest achievement as having created the most comprehensive publicly accessible map of Ashgabat, the capital of Turkmenistan.
Niklas Weber, a German physician, examined the tick-borne skin disease in Quilcacé, El Tambo, Cauca, Colombia. He uses OpenStreetMap on Locus-Map intensively on his travels as Carlos, aka kaxtillo reports in his blogpost.
User malenki died in a hiking accident in Spain in 2016. A memorial stone has now been dedicated to him in his home village of Kleinhartmannsdorf.
All mappers use taginfo at some time or another. Jochen Topf, the developer, blogs that the tool now supports 18 languages, after the addition of Farsi (فارسی / Persian) as the first right-to-left language. If you can help with translations, either by adding a new language or by completing an existing one, please have a look at this wiki page.

FOSS4G 2018 Tokyo will be held at Komaba Research Campus of the University of Tokyo on November 9th and 10th.

Humanitarian OSM

Ramani Huria 2.0, a local community-based mapping project in Dar es Salaam, reports on an initiative to map the local drainage network in order to develop flood models. As a rapidly expanding coastal city Dar is often affected by high water levels. The model should help understand flooding, its impact, and attribution of limited infrastructure, maintenance, and solid waste on flood risks.
The type, dimension and state of drainage infrastructure in 200 flood prone sub-wards will be mapped over 6 weeks this summer. The project is supported by the World Bank and HOT.
The Hindu, an Indian newspaper, wrote about both crisis mapping in general, and a session hosted in a hotel in Delhi by Medecins Sans Frontieres for explaining the Missing Maps project and training of volunteers.
A new open access Perspective Article by GIScience Heidelberg and Red Cross (UK/Germany) discusses the Missing Maps Approach and its potential within the Red Cross and Red Crescent movement

Education

The question on how to query Overpass with the API development environment Postman was answered on GIS StackExchange.

Open Data

Aerial missions using LiDAR provide very precise elevation models. With the publication of Lidar point clouds for Estonia, Martin Isenburg of rapidlasso Gmbh reflects again on the question of access to such data. National agencies often keep such data behind very high paywalls. Previous blog posts (1, 2) questioned whether the income of around £323,000 per year between 2007 and 2014 made it worthwhile to keep restricted access to such accurate elevation data.
At the ToulouseSpaceShow 2018 GIScience Heidelberg announced a forthcoming new landuse data set combining OSMlanduse.org with EU Sentinel 2 data, initially for all of Europe

GIScience Heidelberg published a new Jupyter Notebook which demonstrates how to use the OpenRouteService Isochrones API to analyse health care accessibility in Madagascar.
Anusha Singh continued working on the web based public transport editor. According to her diary post she added a lot of improvements like a beginner and an expert mode and interactive tutorials on how to use the web app.
Florian Schäfer worked on improving JOSM’s Wikipedia plugin during his Google Summer of Code project. According to the documentation he added validator warnings if wikipedia and wikidata don’t refer to the same item and made wikidata items with coordinates a lot more accessible than they were before. Florian also helped out other GSoC students and has maintained the Mapillary plugin over the past 4 years.
Srikant Chepuri wrote a diary post about the progress made on GTFS2OSM, a GTFS to OSM integration tool. GTFS2OSM aims to make use of a GTFS feed to add missing public transport elements to OSM easier.
Matias Dahl, who wrote a blog post in 2015 about tag transitions of amenity=* , has created a new website called tagdynamics.com that is intended to provide more insight into the transition of OSM tags. The work-in-progess website shows how tags, values or tag/values like building=yes have transitioned from or to over the time. The source code is available on GitHub.

Releases

Pic4Review, a simple OSM editor allowing contribution based on street level pictures, just received an update according to this tweet. The new version improved the UI, "mission" management and added German as an additional language. (Missions are thematic categories, examples here on the dev instance).

Top right: New Turn-by-Turn Routing Helper
Bottom right: New Fast-Forward routing, based on continuous sequence of ways from other route relations. Here it’s proposing to add 50 ways in one go. 1 | © Polyglot CC0

Mapping

The JOSM PT_Assistant plugin for public transport mapping gained several new features :
- A wizard to help set up the JOSM environment for mapping public transport and other route relations
- The double split map mode
- Various bug fixes and improvements
- Routing Helper, which can be invoked from within the Relation Editor.
This last addition may have a big impact on how bus itineraries are mapped from now on.

User Polyglot is creating screencast videos to show how it works and with various tips and tricks, both for working with JOSM and for mapping route relations in particular. They will be linked from the wiki documentation page.
Delhi-based mapper contrapunctus discovers that mappers themselves benefit from what they have added to OSM. This was proved several times during a recent trip to Himal Pradesh, and during his survey of the longest bus route forming a big circle around the city.
The German Federal Ministry of Education and Research is supporting the so-called Terrain Projekt (automatic translation) that aims to develop a portable routing device for blind or visually impaired people. One subproject has now introduced an early prototype in the German OSM forum (automatic translation). A paper on this topic is closed access but will be released to the public soon.
The Open Data Institute (ODI) published a blog post explaining contributions from large corporations such as Microsoft, Apple, Facebook and others to OSM. The blog post includes a list of success factors for such corporate projects, which could be summarised as: be more open and cooperative than OSMF’s direct editing policy requires.
User higa4 analysed the state of mapping coverage of Japan.
Eric Gunderson, Chief Executive of Mapbox, tweeted “done with buying satellite imagery…”. Only time will tell if this is hyperbole.

Community

OSM now has a caching server in South Africa as tweeted by OpenStreetMap ZA. As you can see on the map, the new cache server delivers tiles to countries in Southern African countries.
Mastodon the free Twitter clone is also gaining ground in the OSM community. We now know of two instances: French and English.
AMEDD, a Malian NGO, hosted a training workshop on August 13-18 about OSM and free GIS in Koutiala, organised by Saliou Abdou (International Volunteer from Francophonie deployed as an OSM facilitator, a program supported by Les Libres Geographes) with the active contribution of OSM community members from Mali and Benin.
Kinshasa is one of the cities selected by the World Bank as part of the Open Cities Africa project with the aim of strengthening collaboration between the local OSM community and public institutions and contributing to better disaster risk management.OSM-RDC and Potentiel 3.0 designed and organized three days of focus groups for the OSFAC of Kinshasa. Kapay Yongolo was responsible for these three days. Supported by Christian Shadrack, they worked with leaders from the 17 districts of Kisenso and two districts of Matete to identify and map infrastructure at risk during epidemics and floods.

Events

Christine Karch announces the next hack weekend in Karlsruhe on 20th and 21st of October 2018. If you want to participate register on the wiki page.
The UK Mapping Festival 2018 published an appetiser article for the upcoming conference. Topics covered include: secret techniques used by Soviet agents to map London during the Cold War; the evolution of sensing technologies and, an overview of OpenStreetMap.
The SotM US program is online.

Humanitarian OSM

Youthmappers also take care of mapping for humanitarian purposes.
Missing Maps blogged about a training session, led by an American Red Cross GIS team, for the Viet Nam Red Cross and the American Red Cross Viet Nam Delegation. The target was enabling participants to organise community mapping, especially with mobile data collection, and to use GIS tools with open data to generate maps, particularly for use during natural disasters.
HOT received a grant from NetHope, a consortium of NGOs that specialises in improving IT connectivity among humanitarian organisations, with 22 OSM communities as beneficiaries. In a blog post HOT shared its experience teaching school children in Peru using OSM tools and a 360 degree camera to create augmented reality content.
Code for Pittsburgh planned a hackathon with the HOT Team during the 2018 National Day of Civic Hacking, a Code for America project. During the event OSM was introduced to the participants and the theory was immediately converted into practice by mapping 1543 buildings and other features as part of HOT projects.

Maps

Christoph Hormann highlights in a diary entry the stricter rendering of areas that now happens following an upgrade of osm2pgsql. The changes enforce higher standards of QA for mappers, and make life for data consumers easier. Although the change is not limited to multipolygons, the most prominent objects which disappeared from the map were multipolygons. Many of these have already been fixed.
For technical details of the changes refer to the post.
Wikimedia’s map feature improvement project has ended. Wikimedia states that, currently, no more follow-up work is planned. The announcement follows the successful implementation of a couple of new features such as OSM maps and map internationalisation, back-end stability and other improvements that were on the Wikimedia Wishlist.

switch2OSM

Amazon has probably also taken a liking to OSM. Some employees introduced themselves in the German forum and, obviously, also get help with their edits there.

Open Data

Open Addresses surpasses half a billion addresses according to a Tweet from Michal Migurski.

Programming

[1] Biswesh Mohapatra detailed the work he did on JOSM’s PT_Assistant plugin for his GSoC 2018 project. He resolved numerous bugs and added some useful new functionality for working on public transport itineraries and stops, but also for editing bicycle and foot route relations.

OSM in the media

La RZ radio, Buenos Aires, interviewed Juan Blas Tschopp, an Argentinian OSM contributor. The topics covered not only OpenStreetMap, but also Geochicas and the upcoming SotM Latam 2018 event.

Other “geo” things

Shaded Relief introduced a new equal-area pseudocylindrical projection called Equal Earth Projection as a response to the demand for fair maps. In particular those allowing direct comparison of the areas of places in different parts of the world, avoiding the notorious artefacts of a massive Greenland and a tiny Africa. The creators compare their work with other equal-area projections in the article and highlight the advantages of the new way to display maps.
Niantic’s Pokémon Go has been using OpenStreetMap data from the outset, moving to full use of OSM for the map background in December 2017. On the occasion of the second Pokémon Go festival in Chicago, the boss of the company reflects on the first two years in an interview with The Guardian.
Pennsylvania State University introduced nice looking, new mobile-friendly visitor maps with 3D views of campus and OSM as basemap for surrounding areas. At the end of the article you can find links to example maps for the university park.

Mapping

Frederik Ramm has published a code snippet on the dev mailing list, which he used to search for the way with the most relation memberships. The most curious and abstruse discoveries are mentioned in the follow-up messages.
The question “How to tag an address that has no housenumber?” has been raised on the Talk mailing list. The ensuing thread is an object lesson in the difference between the theory of an address being a unique identifier and the reality out there.
Jyri-Petteri Paloposki wrote on the Tagging mailing list that the tagging proposal for winter_service, that was originally developed by malenki, has been put up for voting.
The deletion of trekking sites (legal wild camping) in the northern Black Forest had the unwanted side effect of triggering a discussion about keeping them secret on the German OSM forum (automatic translation). Normally you only get the specific location of the sites after making a reservation and paying a small fee. The idea behind this is to protect the sites from abuse and vandalism, which could eventually lead to their abolition.

Community

Displeasure about the quality of Facebook imports and their collaboration with the community grows. Two of the most active mappers in Thailand are about to throw in the towel and stop mapping.
Printed hiking maps were previously often primarily published by state surveying authorities using their own, official, data. A hiking blog shares (automatic translation) their positive experience with a printed hiking map based on OSM which replaces the out-of-print map from the state survey.
aHaSaN wrote a post in his user diary about the initiative of government institutions and civil society organisations in Bangladesh to use participatory OSM mapping for improving the capacity of communities in climate vulnerable areas as part of the LoGIC (Local Government Initiative for Climate Change) initiative.
User gsa created a map which shows all mountain peaks with a special property. Standing on a summit and looking around horizontally, most of the time one observes a higher mountain. On some peaks, however, which he called “extremal” peaks, this is not the case: If you stand on the top, you are looking down on every surrounding point. The computation of these “extremal” points from the OSM “natural=peak” (and “natural=volcano”) data was performed with GNU Octave. The code is available on Gitlab.
Christoph Hormann sees a need for OSM to have its own system for project organisation and related communication, task and issue tracking. He sees the widespread use of GitHub repositories to track a host of OSM-related activities, both by OSMF and related parties, as a clear signal that issue tracking is important within the OSM community. Because GitHub’s orientation is towards software development it can be an unfamiliar environment for many OSM contributors. In addition there may be issues of principle, due to GitHub’s commercial status, for others. He therefore suggests setting up our own self-hosted open source solution.
Martijn van Exel has recently introduced a new tool called meet your mapper, which lets you find mappers in a particular area. Now he has improved the tool based on user feedback. The main change, described in his user diary, is the addition of rectangular bounding boxes to select an area. These supplement the previous use of OSM relations. Other new options include: an alternative Overpass API server and a local quantitative assessment of the mappers in the area, similar to Pascal Neis’ How Did You Contribute.
Pierre Béland published a new blogpost on OpenDataDRC (an initiative from OSM-DRC and Potentiel 3.0) and he proposes quality indicators and map visualisations to identify irregular geometries and overlaps of buildings to help OSM communities assess and correct quality problems for their area.A sample from the 12 cities that have started participating in the Open Cities Africa project was used. He found out that on average 27.8% of buildings in the sample have an irregular geometry and 5.6% have overlaps or are an invalid polygon. However, there are important variations and some peaks with Pointe-Noire having over 24% of buildings with overlapping ways or invalid polygons and Victoria with more than 72% of all buildings with irregular, i.e. non-rectangular, form.Various explanations are proposed such as the lack of good imagery for the area, dense urban areas, mapathons with inexperienced contributors and low number of local contributors.

OpenStreetMap Foundation

The minutes of the OSMF board meeting on August 16 have been published. Topics included: introduction of mutli-annual or life membership categories; the “Microgrants” program currently under development; GDPR; and the activities of the Advisory Board.

Events

Paul Desgranges and others from the French community provide another perspective on the recent SotM 2018 conference. As well as reports on a selection of individual talks, the section “La tendance générale” looks at implications for the general direction of OSM. (automatic translation).The selection of talks available as videos on the YouTube channel have meanwhile been extended.

Humanitarian OSM

luc_kpogbe wrote a diary post on how HOT microgrants have helped in mapping the northern regions of Benin, in order to have a better knowledge of the territory and be able to react effectively in the event of crises or epidemics, since these regions are still poorly mapped,F not only on OSM. Thanks to a microgrant, OSM in Benin was able to acquire smartphones for field data collection.
Rebecca Firth wrote an article at the HOT website about her thoughts on inclusion at the SotM. As Rebecca laid out she felt a change in topics around inclusion, particularly gender, and explains the reasons for her positive impressions.

Maps

Daniel Koć, one of the maintainers of OSM Carto Map Style, wrote a diary entry about his personal design principles of the map style. His intention is to start a series of articles to introduce the OSM community to general map rendering challenges using OSM data from the project maintainer’s point of view.
Discostou36 suggests (automatic translation) in the German forum that a special map could be developed listing facilities relevant for families with small children. amilopowers realised the idea in the form of a uMap map.

switch2OSM

Neil Gunto, the maker behind crazyguyonabike, a website hosting bicycle touring journals, forums and other resources, wrote a comprehensive article about his switch to OSM. The recent Google Maps price hike led him to look for alternatives. In this article he explains in detail how and why he switched to Stadia Maps, OpenCage Geocoder and Leaflet. In his conclusion he wrote: This is an example of why switching to OSM is actually a Step Forward – it gives you far more control than you had with Google.

Open Data

The Belgian cadastre is now available as open data as Joost Schouppe reported on the Belgian mailing list. He notes there are some quality issues with the data.

Licences

Maurizio Napolitano noticed the Community Data License Agreement from the Linux Foundation and asked on the Talk mailing list whether it was compatible with OSM. His interest was whether it would permit the import of whosonfirst data, which is released under that licence.

Software

Since Garmin removed their app Navigon from the market in May, the unrelated app Navigone from Sygic has appeared. Navigone is a renamed version of the OSM-based navigation app Be on Road.

Programming

Kevin Kenny wrote on the Talk-US mailing list that he has been using the code Phil Gold and Richard Weait developed to render US highway shields for several years now. However, over years during which he used the code and made a number of changes, he became out of sync with the main development line. Since he considers the distinction among highway shields is really necessary for the map in the US, he has created a repository to share his code. Kevin is inviting anyone to help with his project.
Christoph Hormann wrote a blog post about the rendering of ways on embankments. Unlike man_made=embankment, the additional tags embankment= and cutting= on highway or railway will not be rendered by the standard OSM Carto style. In his article he explains why this problem is more tricky than it appears and suggests a possible solution.

Releases

A JOSM hotfix has been released to improve the robustness against a Debian/Ubuntu bug caused by the GNOME ATK wrapper. The new version also includes some minor improvements.
Nominatim 3.2.0 has been released. GeoJSON and GeocodeJSON have been added as new output formats. The reverse geocoding algorithm has been rewritten to improve results in sparsely populated areas and when looking up administrative entities.

Other “geo” things

Oliver Beattie complained on Twitter that he had to turn off his popular radius tool because of Google’s price increase. Soon after the first response suggests he starts using OSM.
An article on Geospatial World describes how technologies such as remote sensing, GIS, and satellite imagery have played a crucial role in disaster management during and after the massive deluge in the southern Indian state of Kerala.
The UK plans to start working on a satellite system to rival the EU’s Galileo, because, as a third party country, it will not have access to the more precise, non-public service of the Galileo system, after Brexit.

Mapping

The city of Stuttgart allows OSM to use its aerial imagery, which has a ground resolution of 20 cm. This step was discussed with the local OSM community during the last local OSM meetup where the city representatives also asked what data could help OSM further.
On the tagging mailing list Joseph Guillaume introduces his proposal for canal=qanat; these are underground channels for conveying groundwater.
On talk-GB Microsoft asked for help with some unnamed roads that they have identified.
[1] Nick Johnston wrote a blog post about mapping Britain’s paths in OpenStreetMap. He includes much background information on public rights of way paths, He got the data for the paths in his home region Gloucestershire from Rowmaps and surveyed using OsmAnd with the tracks in the background. Even if you have no intention to map paths in the UK, just the pictures of his beautiful home region make the article worth reading. He ends his article with the warning that you should not import the data straight away for a number of reasons.
User MKnight has refined (automatic translation) the reservoir Lac de Petit-Saut in French Guiana in weeks of hard work. He also summarises the negative environmental consequences of the dam.
OpenSnowMap.org’s maintainer yvecai has compiled up-to-date statistics about ski pistes in OSM. The combined length of all ski pistes in OSM exceeds 100 000 km!
Land parcel data in OSM is mentioned in a study about the impact of spatial data on the development of slums in cities with rapid urbanisation. According to the report, OSM has not reached a consensus as to whether parcel-level data should be mapped due to concerns about data quality, validity, and maintainability. The same applies to metadata on parcel data. It also mentions that mapping parcel data is becoming more common.

Community

We recently wrote about Matthias Plennert’s article “The social construction of technological stasis: The stagnating data structure in OpenStreetMap” in the journal Big Data & Society. The article in general and one of the key points in the article, i.e. that hidden gatekeepers would be responsible for technological stagnation in OSM, caused some discussions. The author responded to the feedback in a special article.
Noémie Lehuby, Florian Lainez, Flora Hayat and Jocelyn Jaubert have revamped the OSM France website. This was also discussed on the Talk-Fr mailing list. (automatic translation)
MySociety, a UK-based non-profit organisation, providing technology, research and data to help people become active citizens, is looking for worldwide electoral boundaries. David Earl forwarded the query to the OSMF mailing list.
A lot of text about Facebook and its contribution to OpenStreetMap has been written recently. LukeWalsh’s article provides a new perspective on it. He wrote about his experience during the college rotational program, when his placement was at the Facebook department, which makes OSM contributions.
The Kosovo community now has a Kosovo-wide Telegram group. Recent topics include open data and the naming of things in an ethnically diverse country. All mappers from anywhere in any language are welcome.
United States ambassador to Turkmenistan, Allan Mustard (OSM apm-wa) wrote two articles about his work on OSM, currently the best map of Turkmenistan available to the general public. As you can read in one article, being an ambassador has the advantage that you can use the head of the Motor Roads State Concern as a QA tool. In his second article he gave some insight into his tour to a southern Balkan Province in Turkmenistan where he updated road information and collected POIs, GPS traces, and Mapillary pictures.

Imports

Andrew Harvey plans to import buildings in the Australian Capital Territory into OSM and started the required discussion on the import mailing list. The import would add over 60,000 buildings with over 500,000 nodes to OSM but does not include address data.
The import of road network data is planned in Kerala, India, a region affected by severe flooding recently. The data was generated by Facebook making use of machine learning. The plan is to allow Facebook’s mapping team to do the initial import, after which the OSM-India community will validate the data. The local community requested Facebook’s assistance with this import. However, during the discussion it was highlighted that the import guideline was not followed exactly and some remarks were made.

Events

FOSS4G TOKAI 2018 (automatic translation) was held on Aug 24-25 in Tokai. The organising committee published the collected tweets of the event and published a video of the “core day” as well.
Mapping events will be hosted during OSM Geography Awareness Week on Nov 11-17, 2018 in several places around the world.
Michael Schultz from the GIScience Group at Heidelberg University invites participation in a validation mapathon on September 13 during EuroGEOSS in Geneva. The goal is to validate a forthcoming Landuse-Dataset that is being generated through fusion of OSMlanduse Data and Sentinel-2 Data using machine learning.

Humanitarian OSM

The World Bank is funding the improvement of OpenStreetMap-Analytics (OSMA) with new functionality through the project Open Cities Africa and the Global Facility for Disaster Reduction and Recovery (GFDRR). HOT reported at FOSS4G. The development, as well as the hosting of the project, is being carried out by the Heidelberg Institute for Geoinformation Technology (HeiGIT).

Maps

Laurence Tratt complains on Twitter that he can’t really read anything on the “official” osm.org map in those countries where no Latin characters are used. Laurence knows about openstreetmap.de, but looks for a map listing names in English (Munich, not München – or Milano = Milan and not Mailand. )Sven Geggus maintainer of the German style and the localisation code used there (available from here), thinks that a change from osm.org is barely possible with the currently used technology. However, in his opinion, this issue should also be addressed as part of the switch to vector tiles. In principle, however, the operation of an English version of the localised map would not be a big problem. Sven already runs a server for his employer’s projects.
OpenAndroMaps, a website for free Android vector maps, now provides additional information like peaks, capitals and ocean depths. The maker of OAM explains his motivation and gives some background information in a blog post.
Daniel Koć, maintainer of OSM’s main map style on osm.org, has written a second article about his personal design principles for the OSM Carto map style. It discusses why the size of a feature is the primary property considered for showing some objects earlier than others. The article also has hints on how to choose a proper zoom level for starting to show them.
Christoph Hormann addresses the possibilities of using patterns to mark different area types in his blog post “More on Pattern use in Maps”.

switch2OSM

The website wedemain.fr published (automatic translation) an article about how local authorities and administrations are using open-source alternatives to Google services. The recent change by the department Maine-et-Loire from Google Maps to OSM and other institutions mainly to Framasoft is discussed. The association Framasoft hosts many open source services, free of charge.
Gadgets360 published an article about some companies that have based their business model on free access to Google Maps. The article examines the trouble they are now in and provides some information on alternatives, including OSM.
etourisme.info recommends that Tourist Offices switch to OpenStreetMap and explains what other benefits this brings on top of the saved G-Maps fees. (automatic translation)

Software

An overview of important OSM apps for Mobile, classified according to purpose, was made for a mapathon event in Kinshasa.

Programming

Fabian Kowatsch from the Heidelberg Institute for Geoinformation Technology (HeiGIT) published a first draft of the documentation of the ohsome API, which is a REST API for analysing the history of OSM data through the OSM History Analytics platform Ohsome.org.
manoharuss gives a short introduction in his user diary on how to use OSMCha to find suspicious edits in OSM.

Releases

Simon Poole announced the release of Vespucci 11.1 BETA. The newly implemented features include:
- improved preset handling
- lookup in taginfo now happens manually for the recently introduced “auto-presets”
- improved copy and paste of tags
- more minor changes.

Did you know …

… the website autobahnkilometer.ch created by dktue? He has, according his announcement (automatic translation) in the forum, created this page to measure the current length of the OSM motorway network in Switzerland and to count the tagged motorway kilometres.
… the site share.mapbbcode.org that allows you to easily create and share maps with custom markers and geometries? You can invite others to edit or view your map. The site also provides [map] bbcode that is supported by some forums.
… the site mundraub.org? Originally used mainly in Germany, the user base of the site is expanding. The name “mundraub” means petty theft of food. The sites shares the location of plants, mainly fruit trees, that are freely available for harvesting by everyone.

OSM in the media

Our map was vandalised recently at a prominent location. As usual the offensive data was fixed after a very short time by volunteer OSM contributors. This time the data was corrected within two hours. Unfortunately Mapbox, whose maps are used by many companies including SnapChat, pulled the data for updating their maps during this two hour window. Hence the vandalism was visible to a very large audience and found a loud echo in the media with Techchrunch, BBC, Gizmodo, Buzzfeednews and many more reporting about it. In an official article OSM condemns this kind of vandalism.

Other “geo” things

Melanie Froude has set up an online tool that allows mapping of landslides. Dave Petley wrote a blog post about the new tool, where he mentions it’s still experimental. It provides a global and regional view of deaths from landslides. Both Melanie and Dave are from the Department of Geography, University of Sheffield. They also authored Global fatal landslide occurrence from 2004 to 2016.
As Eric Wilson reported on Twitter, the Russell Senate Office Building in the US was renamed to John McCain Senate Office Building on Google Maps after McCain’s death. According to the Washington Post it is not clear yet by whom and why the entry was changed. The name was later reverted to its previous version.
Agence France-Presse has published a map illustrating emergency medical care in France. All white areas are more than 30 minutes away from an emergency department.

EU upload filters and ancillary copyright

The proposal to reform the EU copyright was originally suggested by Günther Oettinger during his time was the EU Digital Commissioner (2014-2016). The EU’s controversial reform, may introduce upload filters and ancillary copyright. It also has only a very limited exception for text and data mining. A key hurdle was passed last Wednesday after the majority of members of the EU parliament voted in favour the proposal, with only slight modifications.Many online communities protested against the proposal in the hope that the EU Parliament would decline it again, as they did in July 2018. The concern is that the new law will require all parties in the EU to implement upload filters, i.e. censorship infrastructure and as such, it will become a big hurdle for projects with user-generated content like OSM or Wikipedia.Wikipedia visitors in many EU countries were met with a black banner, urging them to defend the internet, and some Wikipedia editions were shut down completely showing only a black protest message. OSM in Germany with its local chapter FOSSGIS participated in this protest by replacing every tenth tile with a protest message on a black background. The OSMF Board did not take a stance on the matter although there was and still is some noise on the OSMF mailing list.The new copyright law still needs parliamentary approval before it will become law. By passing the draft, the EU parliament opens negotiations with the European Council and the European Commission. If, as currently expected by the lawmakers, this version of the law will be approved by all three EU bodies, it could be ready for a final vote by the end of the year.

Mapping

Osmose now allows potential errors to be exported as KML files. You can import these files into apps, such as Maps.me, to assist in checking on the ground.
The Osmose QA tool now includes a layer with traffic signs from Mapillary where the equivalent information is missing from OSM. At the moment, the layer is available in France, Brussels and parts of Germany.
The question as to whether waterway=riverbank is an ‘old scheme’ and should be replaced by natural=water + water=river was discussed on the tagging mailing list.
On the tagging mailing list, terraced buildings – rows of houses with shared walls – were discussed.
Andrew Wiseman from Apple’s mapping team started a project to help improve the road networks of Senegal, Côte d’Ivoire, Tunesia and Uganda and he asks the local mappers on the respective countries’ mailing lists where to direct his team’s attention.
Telenav created MapRoulette tasks for highways in OSM lacking a speed limit, but where data are available from image recognition processing of OpenStreetCam photos. So far the new Maproulette challenge is limited to Detroit.
A reddit user asks whether tools exist that semi-automatically trace buildings from images. The answers included pointers to Microsoft’s buildings footprints, RoboSat from Mapbox and the JOSM plugins building tools, Lakewalker, Scanaerial, Tracer2 and mapathoner. However, you should make yourself familiar with the Automated Edits code of conduct.
Harry Wood re-iterates Christoph Hormann’s call to double check multipolygons. As reported osm2pgsql is repairing fewer errors than it did before it was updated. Now errors are just rejected: leading to gaps on the map.

Community

The OsmAnd team launched a short survey, asking if you know about their in-built Travel Feature, which uses data from Wikimedia’s Wikivoyage project.
OSM is becoming a multi-generational project. Florian Lohoff’s son, born when he joined OSM in 2008, has now also started contributing to OSM.
A bicycle enthusiast from France created tutorial videos (automatic translation) explaining the many features of OsmAnd in French. English documentation can be found on the official website.
We reported earlier about a quality analysis tool written by Pierre Béland and used to analyse 12 African cities. The tool has now been used to analyse 25 Tasking Manager tasks from August. Maps by each contributor allows rapid visualisation to detect those buildings that need to be revised as a matter of priority. Once again there is variability in the quality of building geometries and the number of topological errors. This analysis suggests we need better monitoring tools to follow up on the work done at mapathons by inexperienced mappers.
Tigerfell wants to rewrite the Relation-Template for the wiki. He explains his motivation in a blog post and is inviting you to participate.

OpenStreetMap Foundation

A new server, named pyrene, was added to our tile rendering cluster. It is located in the OpenSystems Lab, based at Oregon State University, Corvallis (USA), and should reduce tile latency for North American users.

Events

The FOSS4G Belgium Conference will be held on October 25, 2018. The organiser, OSGeo.be, just announced the continuation of the annual conferences that started in 2015 and is calling for papers, maps and sponsors.
The FOSS4G SotM Oceania, a joint conference of OSM and FOSS4G communities of Australia, New Zealand, and the Pacific Islands, will take place in Melbourne on November 20-23, 2018. The organisers are looking for open geospatial projects for the community day on the last day of the conference.

Humanitarian OSM

[1] HOT announced the launch of Visualize Change, a tool that can create an embedded and downloadable visualisation of the changes in OSM over time. The tool was shown to the public at the recent FOSS4G.
CartONG, a French NGO, is looking for (automatic translation) someone willing to apply for a civic service (automatic translation) position. Missions include planning and hosting mapathons, taking part in the operations at CartONG and raising the awareness of new audiences.
Janet Chapman is organising a Global Mapathon from 28th to 30th of September 2018 to help end female genital mutilation (FGM).
Luc Kpogbe from OSM Benin reports that they are mapping their northern border region and the city of Tanguieta. They are training young mappers and are able to provide them with smartphones thanks to a micro-grant from HOT.

Education

Marena Brinkhurst and Jinal Foflia, from Mapbox, together with Yves Barthelemy, of the Zanzibar Mapping Initiative, and Nuala Cowan, of Open Cities Africa, hosted a 2 day hackathon in Zanzibar following the FOSS4G event in Dar-Es-Salaam.This resulted in:
- tools for comparing imagery (2 islands of Zanzibar were flown over with drones to create fresh high resolution imagery)
- interacting with crowd-sourced data
- visualisations of school enrolment, urban development, and flood prone areas
- an interactive tour of cultural heritage sites in Zanzibar

Maps

It looks like many users originating from Western countries have a problem with the “main map” on openstreetmap.org as they are only familiar with the Latin script (we reported earlier). Sven Geggus explained in detail how he copes with localisation in the German map style on openstreetmap.de. Specifically, he makes notes about proper tagging, what one should care about and which problems might arise. In addition, he presents a feasibility study in case OSM.org should one day be converted to vector tiles.

switch2OSM

The public transport app Mutti, for iOS, switches (automatic translation) from Apple Maps to OpenStreetMap.

Open Data

WeeklyOSM often receives links to papers about OSM in science journals that are unfortunately closed source and – except for the abstract – behind a paywall. The EU and some national research funders have announced a plan to make research papers free to read. The new policy will be implemented from 1 January 2020.
The saga of non-open addresses in the UK continues. Owen Boswarva summarises the current position as the national Geospatial Commission gets up to speed.

Software

cartONG, a French NGO, prepared a comparison between the three commercial UAV post-treatment applications: Pix4D, ESRI’s Drone2Map and AgiSoft.

Programming

Andrew just announced the release of AgentMaps, a Javascript library for building and visualising dynamic social systems on maps.
Simon Poole has added a function to OSM that provides a file with a list of deleted user account UIDs. Most of those user accounts have been deleted as they were used exclusively for spamming. Pascal Neis’ tool How did you contribute is already making use of the list.
Sabrina Marx, from the Heidelberg Institute for Geoinformation Technology (HeiGIT), published a step by step tutorial in a Jupyter Notebook on analysing HOT Tasking Manager projects using the ohsome API.
OSM user Glassmann documented his approach to generating a vector tile overlay for use in iD in his OSM diary.

Releases

Wambacher’s OSM related software list has been updated. Most recent version changes were Komoot Android, Mapbox Nav SDK , Mapillary Android, Naviki Android, QMapShack and Vespucci.

Did you know …

… JungleBus, an Android mobile app that makes it easy for beginners to collect bus stops all around the world.
… OpenBeerMap, it allows the user to specify their favourite beer brand and then displays pubs offering it on a map. The question of whether the beer brands offered in pubs merit being added to OSM is more contentious though.
… the Christmas map, where you can already start adding events like Christmas markets?

Other “geo” things

Randy Meech (ex CEO of Mapzen) outlines, in a long twitter thread, the philosophy behind his new business, Street Cred labs, which is developing new approaches to capturing POI data. Of particular interest are his remarks about how the data may be licensed. TechCrunch has written a short article about the company.
From time to time people use OSM to add fantasy locations. The medieval fantasy city generator might help people who are looking for a nice looking fantasy map.
The Open Geospatial Consortium (OGC) is looking for comments on the draft Geospatial Artificial Intelligence (GeoAI) Domain Working Group (DWG) Charter, that is intended to provide a forum for discussion and aims to ensure interoperability of OGC standards in AI applications.
The Guardian reports that sheet 440 is the worst selling map in the OS Explorer series (1:25k), covering an area of over 800 square kilometres in the far north of Scotland with a population of less than 200, and ‘a few dozen’ buildings. The best selling map, of Snowdonia, is 180 times more popular. OS surveyor Dave Robertson also explains how new roads are mapped – not much different to how we do it in OSM.

Dosažitelnost za 5 (zelená) a 10 minut (modrá) – open source modul pro GraphHopper [1] | © GraphHopper, © přispěvatelé OpenStreetMap

OSM CZ

Poštu pro doménu openstreetmap.cz nyní spravuje server, kde běží i web. Jedná se o aliasy dev@, weekly@, sotm@ a fody@.
Fody je nasazeno na openstreetmap.cz v produkčním režimu. api.openstreetmap.cz prý plánuje walley vypnout.
Nová verze webové aplikace osmap.cz – Fody, vrstva Strava heatmap, ikona pro rozcestníky jen s tourism=info.
Je někde návod pro nováčky jak postupovat ohledně poštovních schránek?
Problém s aplikací osmap.cz a rozlišením vývojového a produkčního systému – fotky se nahrávaly ve vývojové verzi Fody.
Výzva k projektu revize a úklidu českých stránek na OSM wiki.
Umělé vodní toky pocházející z importu DIBAVODu a co aktuálně s nimi.
Jak značit náhon pro vodní mlýn?
Hledají se přednášející na letošní SotM 17. listopadu v Brně.
Tagování POI na ploše objektu a ještě jednou jako bod uvnitř. Co s tím a kdy je to dobře a kdy špatně?
Jak tagovat bránu na silnici přes vojenský újezd, která je v drtivé většině (mimo vojenská cvičení) otevřená a jezdí se tam?

OSM SK

Výzva k podání návrhů na podzimní mapping party a zároveň valnou hromadu občanského sdružení freemap.sk.
Souhrn novinek na freemap.sk. Detailnější výškový profil využívající nové API pro výšky.
Chybějící deklarace práv a majitele v Kostolianech a kde takové věci evidovat souhrnně.
Bližší informace k API pro získávání nadmořských výšek.
V Bratislavě najdete na zastávkách MHD mapku okolí využívající OSM se správnou deklarací práv a majitele.

Mapování

Když David Earl obhlížel nové stavby v Cambridgi pro zmapování v OpenStreetMap, potkal člověka z národní kartografické agentury Ordnance Survey, který dělal to samé. My víme, která mapa byla aktualizována první…
Použití tagu type=watershed bez existujícího návrhu nebo jiného návodu vedlo k diskuzi na tagging mail listu, která měla pomoci s definicí, kdy je vhodné tento tag použít. Dle všeho jsou zde ale pochybnosti, zda povodí do OSM vůbec patří.
dannykath z data týmu Development Seed píše ve svém deníku o mapování komerčních farem v Etiopii. S použitím JOSM bylo v rámci projektu Světové banky zmapováno více než 190 farem v nížinné Etiopii. To si vyžádalo použití celé škály satelitních snímků pro zajištění rozumného pokrytí, speciálně ESRI World a Sentinel-2 Agriculture.

Komunita

Rory McCann navrhuje umožnit uživatelům mazat komentáře k jejich uživatelským deníkům. Mnoho lidí tuto myšlenku kritizovalo.

Nadace OpenStreetMap

Mikel Maron poslal aktualizaci ohledně úsilí Nadace OSM proti navrhované copyrightové direktivě EU (o které jsme informovali dříve), která může ve stávající podobě postihnout i OSM. Vypadá to, že diskuze vedla k novým závěrům.

Události

Švýcarská konference WikiCon 2018 se bude konat (automatický překlad) 5. – 7. října v St. Gallenu. Budou zde dvě přednášky související s OSM a stánek bude mít i švýcarské zastoupení SOSM.
Švýcarská akce DINAcon 2018, konference pro digitální udržitelnost, se bude konat (automatický překlad) během října. Švýcarské lokální zastoupení SOSM bude mít na akci 19. října svou sekci.
Konference FOSSGIS 2019 je plánována na 13. – 16. března v Drážďanech. Potenciální přednášející byli vyzváni k na zaslání návrhů svých příspěvků.
3. října bude QGIS.NL pořádat v Nieuwegeinu poblíž holandského Utrechtu komunitní den.

Humanitární OSM

HOT publikoval článek o nedávném mapathonu organizovaném nepálskou skupinou GESAN. Akce cílená na studenty geografie se zaměřovala na mapování specifických oblastí ohrožovaných katastrofami.

Mapy

OpenTopoMap běží na záložním serveru, pravděpodobně do konce října, což znamená, že malé přiblížení nejsou aktualizována a velká nejsou renderována. Ve stejném příspěvku na fóru (automatický překlad) je zajímavá diskuze ohledně netriviálního vykreslování jmen jezer.

Přechod k OSM

Francouzský web L’informaticien nabízí podrobný článek porovnávající (automatický překlad) OpenStreetMap s mapami od Google, ale také s IGN (oficiální data pro Francii).
Wetter.com je široce známá služba pro předpověď počasí v Německu. Jejich web nedávno přešel na OSM.

Licence

Gaël Musquet kritizuje (automatický překlad) zprávu od francouzské vlády za popis svobodných a share-alike licencí termínem “kontaminace” jako opovržlivého lékařského termínu.
Uživatel Kaxttillo se začal zajímat (automatický překlad) o použití OSM map ve filmech a televizních seriálech a zve ostatní aby se přidali. Přemýšlí mimo jiné, jak by v těchto případech měla vypadat deklarace práv a majitele, když v titulcích nic nenašel.

Software

Yuri Astrakhan oznámil vylepšení OSM wiki o rozšíření Wikibase. Wikibase ukládá data z OSM wiki ve strukturované, strojově čitelné podobě jako například Wikidata. Dobrý začátek pro zájemce o detaily tohoto tématu je stránka na wiki OSM Wikibase.

Programování

Andrei Kaschcha (Anvaka) oznámil velmi rychlou prohledávací knihovnu napsanou v JavaScriptu. Můžete si ji sami vyzkoušet v živém demu zahrnující routovací grafy pro 6 velkých měst.
Společně s Ralphem Straumannem naprogramoval Riccardo Klinger importní nástroj OSM dat pro ArcMAP a ArcGIS systémy nazvaný OSMquery. Nástroj slouží jako frontend k Overpass API.

Nová vydání

[1] Projekt GraphHopper oznámil vydání verze 0.11 svého routovacího nástroje. Hlavní změnou je dostupnost zdrojových kódů pro isochronní modul. Isochronní API umí spočítat dostupnost oblasti na základě faktorů jako je čas, režim pohybu a počátek. Další vylepšení zahrnují modul veřejné dopravy, rychlejší porovnávání map a představení navigační knihovny.

Věděli jste …

… o nové, k mobilům přívětivější verzi hledání bankomatů na geldautomaten-suche.org?
… o německé iniciativě na vytvoření mapy ochrany klimatu? Obsahuje instrukce, jak zmapovat vaše okolí pomocí OpenStreetMap.
… seznamu mapperských nehod? Je nepravděpodobné, že se za posledních 5 let žádná nestala.

OSM v médiích

Xenius, populární vědecká TV show francouzko-německého kanálu ARTE, se zabývala tvorbou map. Frederik Ramm, Michael Reichert a Joachim Kast demonstrovali jak v terénu prohlédli a pak zmapovali novou výstavbu domů poblíž německého Karlsruhe (stáhněte s anglickými nebo španělskými titulky).

Ostatní geo záležitosti

Grafický designér z Londýna má sbírku fotografií, které budou povědomé komukoliv z OpenStreetMap. Příklady jeho snímků tabulek se jmény ulic jsou prezentovány v The Guardian.
Vizualizace hurikánu Florence od Mapboxu byla použita v článku v New York Times..
Prvním výsledkem publikovaným nástrojem pro organizaci dat o pozorováních Země Swiss Data Cube je vizualizace změn sněhové pokrývky ve Švýcarsku.
Poprvé v historii je možné si prohlédnout velmi přesnou mapu terénu Antarktidy.
Brilliant představil video nazvané “Nepravé okolí na Google Maps”. Nemluví zde o schválně provedených chybách na mapách pro odhalení kopírování, ale o síle firmy Google protlačit své chybné pojmenování, které převáží nad původním místním názvem.
Poznaň zkouší (automatický překlad) samořiditelné tramvaje. Na testovacích jízdách nejsou pasažéři a zatím je vždy přítomen řidič, aby zasáhl, pokud by se něco zvrtlo.

Mapping

User 817817 explains in his blog why he’s mapping surveillance cameras, and he encourages others to map them too. 817817 says that mapping surveillance cameras contributes to both privacy and security and that it will trigger people to reconsider their own privacy. (automatic translation)
Thejesh GN wanted to print some maps with Marble in the Kannada language, which is spoken by 40 million people in southern India. He noticed that this language is underrepresented in OSM. He created instructions to fix that problem using iD.
Voting has started for highway=toll_gantry, proposed to be used on nodes to denote a transponder or camera gantries to toll bridges.
Daniele Santini prepared a proposal for the key assembly_point:purpose= to specify for which kind of hazard – fire, tsunami, earthquake, tornado – an emergency=assembly_point was created.
Joseph Eisenberg is proposing the key prominence= for peaks. While the established ele= provides the value for the height of the peak, the new key is intended to indicate how tall a peak is compared to the surrounding area.

Community

Frederik Ramm started a discussion on the dev mailing list about extending the range of possible user blocks and making them more granular. The questions raised might not be most appropriate for that mailing list.
The Wikibase extension (which we reported earlier), that is intended to store structured tag metadata, is now live. However, response to this promising change has been muted to date.
OpenSnowMap.org’s maintainer yvecai has compared the data at Skimap.org and the ski pistes in the OSM database. Neither project is complete so it is hard to estimate OSM completeness.
The organisation Potentiel3.0 wrote two tweets [1, 2 ] about the QGIS and mobile data collection training for agricultural engineers at the University of Grande Anse in Jérémie, Haiti.
David Morais Ferreira (OSM dmlu) was chosen as mapper of the month by OSM Belgium.

OpenStreetMap Foundation

Frederik Ramm, the OSMF treasurer, is looking for a successor.
The OSMF is asking for feedback on the new Microgrant program.

Events

[1] Mikel Maron tweeted how a cake should look like if it was made for mappers.
The INTERGEO fair, which will take place in Frankfurt from 16th to 18th October 2018, will also host the OSGeo-Park this year. OSGeo-Park informs visitors about Open Source GIS, free geodata, GIS technology, and OpenStreetMap. The organisers are still looking for a A0 printer to print maps on the fair. The program is still a work in progress.
HeiGit will present Openrouteservice.org at INTERGEO 2018 (Frankfurt, Germany 16th-18th October) in the booth of the German Federal Agency for Cartography and Geodesy.

Humanitarian OSM

Nicolas Chavent tweeted from Haiti about his preparation of his second OSM, open data and GIS training week.
HOT prepared a short analysis about the use of available imagery sources. It shows that the majority of HOT tasks use Microsoft’s Bing imagery.
RichRico wrote a post about the cooperation of Development Seed’s data team with HOT in the previous months and detailed the projects they were working on.

Education

In Haïti an 11 day workshop was organised from 17 till 28 of September. During the first 2 days participants were taught field surveying, JOSM, uMap, and QGIS for editing and rendering the data.

Maps

Klokan Technologies tweeted about the simplification of map creation with its MapTiler Cloud product. According to a blog post it is possible to design a personalised map with only five clicks.

switch2OSM

In Belem, Brazil, there is an annual religious parade that attracts two million people. The state IT agency Prodepa has created an OSM-based online map of the "Círio de Nazaré" procession including prominent contact points, specially set up medical stations and time restrictions on road closures.

Open Data

The Open Data Institute launched a fund to encourage local governments in the United Kingdom to release geospatial data as open data and to explore collaborative approaches to data collection, management and use by the Ordnance Survey, OpenStreetMap and other open data or civil society groups.

Software

The Suspect Lists of BRouter, that can help finding errors and inconsistencies in the road network, are now available worldwide.

Programming

Sascha Fendrich from Heidelberg University calculated the size of the OSM history data in terms of raw data as it would be represented in systems programming languages such as C and Rust and derives some interesting numbers in comparison to data structures in XML.

Releases

Daniel Koć, maintainer of OSM’s main map style, just announced the release of a new OpenStreetMap Carto stylesheet. The changes in version 4.15.0 include new colors for gastronomy objects, farmland and societal amenities, rendering implementation of man_made=wastewater_plant and man_made=water_works, new icons, missing country label fixes and many others.

Did you know …

…. Map Compare, which can also be used to show the different addressees of the OSM mapping. The example of Falkirk in Scotland shows that on OSM, what can be seen on the ground is shown as far as possible. A comparison of video and map are worth watching.
… MapRoulette? There are always possibilities to improve the OSM data.
… the tool Who’s That? If you want to lookup the former name of a mapper or you have the former name and want to find out the current username, the tools will do the job.

OSM in the media

The Factor Daily wrote a comprehensive article about OSM. It covers OSM’s relation to Google, what market potential is estimated in the map industry, why companies switch to OSM and the relation to government bodies, the Indian, here in particular.

Other “geo” things

Locusmap tweeted a picture of its map app running on a Samsung Gear under Samsung’s proprietary smart watch operating system Tizen.
Emily Badger published an article with an interactive map in the New York Times about how connected locals in the US are on Facebook.
There is not much time left to take pictures for #WikiLovesMonuments 2018, the world’s biggest photo competition around cultural monuments.
COBI.Bike proposes hardware to interface with your bicycle or e-bike. The app for iPhone is described in this article (automatic translation). It exists for Android too. It uses OSM data for navigation.
Linda (Hecht) Stevens wrote an article on medium.com about her view that the availability of geospatial data like imagery, base maps and localised information, fuel a GIS revolution that has yet produced new spatial analysing tools like for 3D rendering or data visualisation.
kerook.eu published an article about nice looking pouches with OpenStreetMap renderings printed on the fabric.

Mapping

OpenStreetMap Guinea tweeted about the start of their mapping campaign to assist the fight against Female Genital Mutilation (FGM).
Jean-Marc Liotier noticed that schools in Senegal were converted from areas to nodes by multiple contributors, thereby losing information. He discovered, after some investigation, that this was done because of upcoming elections. The organisation wa mbedni, behind the project “Senegal Vote”, was the culprit. The reason is baffling though: they can’t process surfaces in their software. Someone should explain to them that Overpass API can take care of this in a trivial way. (automatic translation)
On Mastodon, Erwin Olario points to a discussion on the OSM Asia telegram channel about a Corporate Editing Heatmap (source code). The tool was created by Jennings Anderson. It shows the areas where commercial, organised mappers are active. The results can be filtered by year and company.

Community

Simon Poole is surprised that there are more mappers active in OSM in the United States on weekdays than on weekends. Are there more commercial than independent mappers? See the charts at osmstats.neis-one.org for reference.
François Lacombe reports (automatic translation) about the OSM-France monthly project last July to import and survey the power grid (automatic translation) in France and what preparations were involved. The quality control tool Osmose played an important role in the process.
Tomasz_W described his experiment on changing the pastel shades of parks in OSM’s main map style Carto to darker colours.

OpenStreetMap Foundation

The Chilean company Altavoz now sponsors the first South American tile cache in the CDN (content delivery network) for tile.openstreetmap.org. (automatic translation)

Humanitarian OSM

Hawa Adinani from Tanzania reports about the completed student training in Dar es Salaam, where 228 sub-wards were mapped to support disaster risk management projects and interventions to clean rivers and drains.
Nate Smith announces a new tool named MapCampaigner, developed by HOT. MapCampaigner’s developers describe it as a “data quality observation tool” intended to follow up on the work done by contributors performing local field surveys tracking specific tags. For example, a report on Botswana flags buildings with missing building:roof or building:levels tags.Critics on the mailing lists respond that this does not address more important data quality issues including those with building geometries, unlike other tools such as Osmose, OSMI, and KeepRight.
Reliefweb reported that the government of Niger partnered with the World Bank and the Global Facility for Disaster Reduction and Recovery (GFDRR) to gather data on flood risks in Niamey, Niger’s capital. Data collected included high-resolution images gathered by drones and 15,000 data points, on households and infrastructure, collected with an open source mobile application by Niger’s OpenStreetMap community. The data was used to model the flood risk of the most vulnerable communities in Niamey.
With extensive mapping activity (1,2) taking place in the aftermath of the earthquake and tsunami which devastated Palu and other parts of the Indonesian island of Sulawesi, readers may be interested in an article in National Geographic about the science behind this event. The recent gathered OSM data has been used by UN damage assessments.

Maps

[1] User acsd has created an online Parking lanes viewer, which includes an easy-to-use editor.
ITO Map is currently having problems with maps that use OpenStreetMap as the base layer – some maps are completely out of service.
An interesting representation of the oceans is shown by Le Cartographe (automatic translation) in their blog.

switch2OSM

Belgian Railways created a map that shows the positions of their trains in real time on a properly attributed OpenStreetMap background.
SomeoneElse wrote a guide on how to switch2osm for Docker on Centos in his user diary.

Software

Vincent Privat, one of the main JOSM developers, deplores how Oracle’s Java v11 keeps removing features that are crucial for JOSM.
Matplotlib, the data visualisation library for Python, announced the release of the version 3.0 with many new features.
Bryce Cogswell (OSM User bryceco), maintainer of the OpenStreetMap editor for Apple platforms GoMap!, announced that the code is now open source on Github.
Daniel writes a diary post announcing the release of RoboSat v1.1.0. Here’s what has changed since the last release: this release is powered by major community contributions ranging from features such as fine-tuning trained models to training and prediction speed-ups, and bug fixes! He also especially thanks to the contributors.
The quality assurance tool osmose has recently implemented checks for unconnected highways and crossing ways for highways and waterways.

Programming

Heidelberg University received funding for the development (automatic translation) of an app called “meinGrün” (myGreen), that is intended to improve the public perception and information about public green spaces in urban areas.

Did you know …

… Bexhill-OSM? It is a passion project that aims to help people discover information in and around the seaside town of Bexhill-on-Sea. Amongst other features, the map offers pedestrian routing and click-to-query-features.
… ReMAPTCHA? As with every anti-spam mechanism it prevents automated programs (bots) from registering. In addition, the ReMAPTCHA challenge will help to correct unconnected ways in OSM’s data.

OSM in the media

The Swiss TV channel SRF broadcast a short documentary in German about the work done by the Missing Maps project to map remote villages in Africa on OSM and enrich the remotely mapped data by doing local surveys.
Steve Bernard, the design editor at the Financial Times, hosted an AMA on Reddit about cartography and data visualisation.
The Haitian OpenStreetMap community of Saint-Marc has asked (automatic translation) that city hall administration help them count buildings in their municipality. They have to map on a shoestring budget and are in need of funding.

Other “geo” things

Sasha tweeted that even Google’s website developers.google.com produced an error message when they exceeded the quota for their own maps API.
Bike sharing providers in larger cities are starting to move from Bicycle Dock parking to Dockless bicycle rental (88 cities in the USA with this kind of bike sharing). Bicycles integrate a GPS and a geolocation transmitter to a central station with the side effect of generating data on how they are used, which in turn results in cities being able to improve their bicycle infrastructure.
The Belgian Ministry of Defence wants to sue (automatic translation) Google for refusing to blur sensitive areas on its aerial images.
In a tweet Anonymaps points to HERE’s xyz.here.com/studio/, which offers the upload, management and visualisation of geospatial data. The tweet can be read as a speculation that HERE will enter into competition with Mapbox studio.
Is your Map and Navigation app keeping track of your whereabouts and using it for commercial purposes? (automatic translation)
The local newspaper Böblinger Bote reports about the project Elevate of Berlin’s Sozialhelden user group, who also run wheelmap.org. The aim of the project is to provide wheelchair users with information such as the operating status of elevators, which is obviously crucial for them to know ahead of time. Real-time information from the Deutsche Bahn, the Stuttgart S-Bahn as well as the transport associations Berliner Verkehrsbetriebe, Region Rhein-Ruhr, and Hamburg will be integrated into Wheelmap.

Mapping

The voting for the key assembly_point:purpose= has started. The key is is intended to be used with emergency=assembly_point where there is a need to specify the kind of hazard – fire, tsunami, earthquake, tornado.
Warin61 noticed that quite a few public transport route relations are broken. He describes the minimal requirements to make them pass the tests from GeoFabrik’s OSMInspector validation tool, which is a lot easier than having to go through the respective wiki pages documenting how to map bus and train route relations.

Community

For the third consecutive year members of the OSM Mali community hosted a week-long OSM training camp in Segou for students of the local university. About 70 students have been taught OSM techniques since 2016.

UBOS, Uganda’s national bureau for statistics, is taking an active role in mapping in OSM. Eleven core members have learned how to use JOSM, QGIS and mobile tools for surveying. There are many challenges to overcome in the country and OSM can help with that.
Matthew Gibb asked experienced OSM mappers for help with the validation of roads in the Florida Panhandle ahead of Hurricane Michael. A task was created for this on the OSM US tasking manager.
In September, faculty and students of the Centre for Interdisciplinary Methodologies, University of Warwick organised a workshop on “Making sense of humanitarian geospatial data to improve the impact of humanitarian interventions on health and wellbeing“. The workshop was co-convened by Médecins Sans Frontières (MSF UK), the Humanitarian OpenStreetMap Team (HOT), the Bangladesh Humanitarian OpenStreetMap Operations Team (BHOOT) and the Heidelberg Institute for Geoinformation Technology/GIScience Research Group at Heidelberg University. The event enabled participants to discuss current approaches and challenges and, most importantly, how to collaboratively address them.
It is October, so HOT commemorates open source by involvement in Hacktoberfest. It is an annual event hosted by Digital Ocean, GitHub and Twilio to promote contributing to open source projects. HOT reminds readers of over 15 of their own active open source projects.

Maps

Cartisan, a small Armenian-based cartography company, is creating a topographic hiking map of Dilijan National Park in Armenia. This will be the first modern topographic map set in Armenia. The map relies heavily on OSM data and the makers have greatly improved the OSM database in the area. The map (sample) is created exclusively with FOSS. They have launched a crowdfunding campaign, together with the local trail-building NGO, Transcaucasian Trail, to get the map produced.
Raymond Inzitari wrote a post about how he started a business making wooden maps as artwork. It took him over six months of development to build a model that uses OSM data, convert it to a geodatabase and output an AI file that is required for the laser cutter.

Open Data

François Lacombe asks whether OSM should participate in events such as the upcoming LinuxFoundation Energy Summit 2018. He argues that it is becoming increasingly common for energy infrastructure operators to replace proprietary data with OSM data.

Software

The next release of VROOM, free software to solve vehicle routing problems, will handle time windows constraints. The feature is already available for beta testing through the project’s demo server.
Sick of expensive map updates for your car’s built-in SatNav? A Raspberry Pi, an LCD screen and a few other components are all that is needed to create a DIY car navigation system that can provide free navigation based on OSM data overlaid on OpenMapTiles. The system can even include a rear view camera.
Generation Streets, a game available on Steam, is using OSM to render an impressive 3D environment.
Richard Fairhurst published a proof of concept for an OSM editor with a GUI that focuses primarily on street level imagery based mapping.

Programming

Due to Oracle’s slimming down and reduction of available functionality in their latest Java release, the OSGeo Foundation is organising a code sprint for their Java-based projects (e.g. Geoserver) at several locations from October 22nd to 26th, for which they are looking for sponsors.
The question whether the time has come to redevelop JOSM due to unpopular licensing changes in Oracle’s Java was asked on the mailing list. Responders point out that JOSM is compatible with the open-source Java implementation OpenJDK, and therefore does not require Oracle’s version of Java in the first place.
The avoid_polygons feature of the OpenRouteService API allows one to find alternative routes during flood events. To integrate real time information, a team of researchers at HeiGIT proposes a workflow to delineate flooded areas using Twitter data.
If you feel limited by how you can integrate a map into your website with Google Maps, Mapbox or Leaflet, you might want to have a look at the Vue.js framework and the d3.js library. Mikhail Panichev wrote a guide on how to create an interactive map with both of these JavaScript tools.

Did you know …

… JOSM’s angle snap feature? This feature helps you to add a line parallel, perpendicular or at defined angles to a base segment.
… the public transport map?

OSM in the media

Centésimo Mono published an interview with Carlos Brys. Carlos Brys reports about the first mapathon in the province Misiones and refers especially to the principle of data acquisition on site. (automatic translation)

Other “geo” things

The Scottish Parliament passed a law banning public bodies in Scotland from making maps which display the Shetland Islands “in a box” (usually located offshore from Aberdeen or next to the Orkneys). Twitter has extensive commentary, and Kenneth Field, an ESRI cartographer, provides a detailed breakdown of why insets (“boxes”) are the sensible cartographic choice.
[1] The University of Heidelberg hosted a mapping session to show the power of crowdsourcing for map validation by collaboratively validating the land use and land cover map of Geneva with ESA’s Sentinel 2 and OpenStreetMap data. A preliminary version of the OSM Landuse Map can be found here.
Chris Wayne wrote an article about creating maps for visually impaired people. In his article he covers the two most common approaches to accomplish this, which are are tactile maps (maps you can feel) and auditory maps (maps that talk in the literal sense).
Another article that addresses the needs of blind people was written by Nicola Byrne. In her article she explains how to use 3D audio to guide blind people around cities, her experience with the system and how it works.
Friends of the Earth have published a 100 second video, with each second representing one percent of the landuses in the UK. The video asks whether nature has the space that it deserves.
The private blog addshore.com published an article about the increase in the number of Wikidata items over the past 6 months. The article gives a breakdown of the increase by region and mentions that the increase in Africa may be due to Wikimania 2018. Over the period about one million geolocalised items were added to Wikidata.

Mapping

Satoshi IIda (User nyampire) announced on Twitter (1, 2) (automatic translation) (automatic translation) about a new aerial image source in Japan. OSM now has permission to use aerial imagery published as open data from Itoigawa city and Atsugi city. He has published this imagery as map tiles and explains how to use it on the Wiki pages Itoigawa city and Atsugi city. (automatic translation, automatic translation)
The voting for the tag telecom=* has started. Values can include exchange, service_device and connection_point. This should enable mappers to map last mile networks and related equipment like DSLAMs (Wikipedia link).
A user of StreetComplete spotted complicated opening hours that don’t fit within OSM’s limit of 255 chars. Whilst all agree that the issue is not limited to opening hours, opinions as to whether such a level of detail should be stored in one value differ.
User jeisenbe proposes a comprehensive handling of default language format for names and places within a region. The voting on the proposal is currently under way: you’re welcome to review it and express your vote.
Nicolas Chavent produced a Twitter moment on the two weeks of capacity building action OSM, OpenData and free geomatics in Port-au-Prince (Haiti) organized in coordination with members of the association Communauté OpenStreetMap Haiti Saint-Marc (C.OSMHA-STM) for people from academic, research, development sectors and the local OSM community, thanks to the support of the Economic and Digital Directorate of the International Organization of La Francophonie
The new value landuse=governmental is proposed to mark land used by government bodies.

Community

On October 11 Nomad Maps finished his cartographic cycle tour through the Andes route having cycled 5000 kilometres. As a result more than 10,000 new objects were mapped and more than 100,000 additional photos added to Mapillary. He had 17 meetings with OpenStreetMap contributors in Colombia, Ecuador and Peru. As a cherry on the pie, Alban Vivert (@Nomadmapper) participated in SOTM Latam 2018 in Buenos Aires to present the results of the expedition and to meet other members of the OSM community. More info on Nomad’s blog and the website of Nomad Maps.
The “Schokofahrt” (chocolate tour) is a decentralized private bicycle tour for emission free transport of chocolate, to promote sustainable mobility and CO₂ neutral transport. At this year´s edition some stairs, that got in the way of the OSM based routing app BikeCitizens, were complicated to overcome with the heavily loaded cargo bikes. The map error was rapidly corrected.
Here are the videos for the State of the Map Latam 2018 sessions on September 24th in Buenos Aires, Argentina.
Sev OSM tweeted about two weeks of OSM and OpenData training in Conakry, Guinea.

Imports

Majka announced that an import of post boxes in Czech Republic is planned. The word import may be wrong here as it is mainly intended to update collection times and re-tag currently not active post boxes to disused:amenity=post_box.
Dannykath from Development Seed wrote about importing of data into OSM. The write-up covers topics like what type of data make sense to import, what is involved in the import process, what needs to be considered before starting, how to document and community involvement.
The Denver Regional Council of Governments is making a dataset available for importing to OpenStreetMap. It contains over 1 million building footprints, with an accuracy of 6 cm. Several import-a-thons will be organised for volunteers to review and ensure consistency with existing OSM data.

OpenStreetMap Foundation

Michael Reichert started a discussion on the OSMF list about the next Board elections: he suggested a slight change in the election calendar and a questionnaire for the candidates, instead of email flooding the mailing list. His proposal is getting positive feedback and further input on the subject.
Christine Karch from the SotM Working Group wrote a comprehensive summary (automatic translation) about her activity over the past year. The ‘Way to SotM 2018’ titled article covers the preparations of the SotM 2018 and other tasks related to her job at this Working Group. She details how she was working on the scholarship applications, the organisation and evaluation of the submitted abstracts for the SotM workshops, lightning talks, talks and other events, the work on the tender for the 2019 SotM and many related tasks. In addition she gave a lot of insight behind the scenes. She explained how helpful it was to meet Nicolas Chavent and Séverin Menard to find a better balance and give the French/African part of OSM some more room and also explained why she thinks that no Code of Conduct for OSM is required. Some minor, maybe more controversial points in the article are her feeling of an overweight of HOT in areas like scholarship and diversity.
User Stereo (Guillaume Rischard) wrote in his user diary about the new Organised Editing Guidelines that were drafted by the Data Working Group and are on the OSMF board meeting agenda of Oct 18th. In his post he explains the context and motivations but does not answer to solitary critic on the content of the new drafted guideline and lack of community involvement during the development.

Events

This year’s Chaos Communication Congress (Leipzig, 27th to 30th of December) will host once again an OpenStreetMap-Assembly. More details on this event on the dedicated wiki page (in German).
The Europe Direct Office in Cuneo (Piedmont, Italy) has organised (automatic translation) a full day around OSM, filled with talks, workshops and a mapping party. OSM will be presented by Marco Brancolini, OSM Piedmont coordinator for Wikimedia Italia; Alessandro Palmas, OSM Project Manager for Wikimedia Italia; and Cristiano Giovando, World Bank and HOT consultant.
A reminder that the upcoming FOSS4G event is on 25 October in Brussels. The planned schedule can be found here.

Humanitarian OSM

The 6th GeOnG forum will take place from October 29th to 31st in Chambéry, France. The GeOnG is organised by CartONG and includes topics like mapping and GIS, mobile data collection and many other technology related subjects that can be of interest in the humanitarian and development sector.
The English city St Albans is looking for crowdfunding to help visually impaired people with content for the app Soundscape. According to the article, the money will be used for a mapathon to train volunteers in OSM, verification and ongoing data maintenance.

Maps

The OSM-based London cycle parking map at stolenride.co.uk got an extra layer that can show the locations where bicycles were stolen based on police reports.
The New York Times used aerial images of the city Mexico Beach taken before and after Hurricane Michael and Microsoft’s building footprints to visualise the extent of the damage. The NYT identified 440 buildings of which 237 were destroyed and an additional 99 were severely damaged.
User SK53 wrote a blog post about how he created an OSM based raster map of the Irish Vice Counties with the proper Irish Grid, hill shading and hypsometric tints for use with MapMate, software intended to record, map, analyse and share biological sightings.
With Locator Map, you can now easily create locator maps in Data Wrapper. A location map is a simple map showing the position of a particular geographic area within its larger and presumably more familiar context. Locator Map is a new map editor to make this process as easy as creating bar charts. Try it here.

Software

Fabian Kowatsch introduces a new ohsome dashboard prototype as a preview on what is possible with the HeiGIT’s ohsome OpenStreetMap history analytics platform which is deployed on a distributed cloud system using Apache Ignite. You can explore the evolution of any available OSM tag over time in arbitrary areas of Germany and calculate some summary statistics.

Programming

In a blog post Alex-7 pointed to a prototype of an OSM map that generates Open Location Codes (OLC) for every position and, vice versa. One can also lookup a position based on the Open Location Code. It works without the need to add OLC related data to OSM.
ENT8R has added the filter parameters user name, user ID and time to the search functions of the OSM-API for Notes and documented the new functions in the OSM wiki.
Trafford Data Lab developed and documented a new Plugin for the Leaflet JavaScript library to show areas of reachability based on time or distance for different modes of travel using the Openrouteservice isochrones API. Included are various examples to get you started.

Did you know …

… Pascal Neis’ tool that generates a list of suspicious changesets based on different adjustable criteria? The results are also available as an RSS feed.
… the OSM changeset analyser OSMCha? It allows you to keep track of edits in changesets. Many different filters can be used when visualising changes in changesets.
… that you can invoke a username based filter with user:username when using overpass-turbo.eu?
… the OSM and NASA based map that simulates rising sea levels following a temperature increase. It allows you to simulate global warming caused land loss.

Other “geo” things

Benjamin Schmidt wrote the article Data-driven projections: Darwin’s world that shows the world map in a projection that centres around Charles Darwin’s route with his ship Beagle. The result is an interesting, but very unfamiliar perspective of the globe, with North America and Eurasia looking unimportant at the edge of the map.
The Relevator published an article showing the estimated regional change in rainfall and snow until 2050 caused by the climate change. The predicted change is displayed on an interactive map on a county level.
Microsoft has made a strategic investment in ride-hailing and on-demand services company Grab as part of a deal that includes collaborating on big data and AI projects.
[1] Neil Kaye published an animated gif on Twitter and Reddit that demonstrates the size of a country as shown in a Mercator projection compared to its true dimension.
A reader of Macrumors took photos of a man wearing a rucksack full of measurement devices walking along a street in San Francisco. The devices were LIDAR, GNSS and cameras for Apple Maps. Cars are also used for this purpose. In June 2018 Apple announced that they will not use third-party data in future anymore (we reported).
