Mapping campaigns

• Puxan can see > a major problem for map quality in online mapathons, which, according to him, have multiplied during the pandemic. He recommends two measures to help improve the quality of data created during mapathons.

Mapping

• Requests have been made for comments on the following proposals:
  • waterway=check_dam to tag structures placed across channels primarily to reduce runoff velocity.
  • leisure=bathing_place for places where access to water to bathe or swim is possible.
  • Survey markers to create a standard way of defining the structure and condition of survey markers.
• Voting on the tourism=giant_furniture proposal for tagging any kind of giant furniture meant to be a viewpoint or a tourism attraction has started (till Wednesday 16 June).

Community

• The Spatial Data Infrastructure agency of the province of Cordoba, Argentina (IDECOR > ), is inviting > you to join the community and map the province in OpenStreetMap. The article was written by Ariel Antieri, a member of the local chapter of the Foundation.
• OpenStreetMap Belgium’s Mapper of the Month for June is Ly Racky (racky) from Côte d’Ivoire.

Local chapter news

• French user Lejun has mapped , in his city, about a dozen vending machines for free menstrual products. While not being the first vending machines of their kind, they seem to be the first to be tagged so thoroughly in OpenStreetMap according to taginfo.

Education

• Arnaud Champollion created a short video in which he shows how OpenStreetMap can be used to create simple maps. While dedicated to educational and orienteering purposes, the ideas given could be applied elsewhere.

OSM research

• At the 12th International Symposium on the Digital Earth, Tahira Ullah, Dr. Sven Lautenbach and others will present their research, on deriving indicators for Points of Interest (POIs) and analysing mixed activities in urban areas. They will suggest a new approach that applies concepts from ecology to POIs from OpenStreetMap to quantify mixed activities.
• Jan Pisl, Hao Li, and others are proposing a method of transferring a building detection model, which was previously trained in an area well-mapped in OSM, to remote data-scarce areas. The proposed model can detect individual buildings by generating bounding boxes around each of them which leads to a significant improvement in the f1-score. They have also presented a walkthrough on how to train your own building detectors using ohsome2label and the TensorFlow Object Detection API.

Humanitarian OSM

• HeiGIT is updating the Open Healthcare Access Map to include all the countries of Central and South America as well as South and Southeast Asia and Sub-Saharan Africa. The application provides insights on travel times to healthcare facilities and population coverage at different scales for a variety of countries.
• HOT has announced the Open Cities Latin America programme, a collaboration with the Global Fund for Disaster Reduction and Recovery and SwissRE Foundation.
• Practical Action Bolivia has completed their microgrant supporting communities in mapping areas affected by forest fires in the Amazon.

Maps

• The CargoBikeIndex aims > to make riding your cargo bike as smooth and effective as possible by helping you to find the smoothest route through motorised traffic. It categorises all the streets in Germany by their cargo bike friendliness, marking them with different colours.
• [1] OpenHistoricalMappers mapped the boundaries of the Inca Empire, which could be the first interactive digital map of the Inca civilisation, whose expansion lasted approximately from 1438 to 1533.
• VISOV used uMap to map alternative hotline numbers during the recent 7 hour emergency phone line breakdown in France caused by the telephone operator Orange.

Open Data

• Supaplex found out that there were no Wikidata items for several villages in Taiwan, resulting in 74 OpenStreetMap villages having no Wikidata link. Supaplex called on the Taiwanese OpenStreetMap and Wikidata communities to take action to establish the missing village items on Wikidata, and link the newly added Wikidata items to the corresponding OpenStreetMap relations.
• Christianlauer shared his experience working with OpenStreetMap data and using open data for business insights.

Licences

• Nuno Caldeira is opening old wounds about a ‘lovely OSMF corporate member’. He says that ‘it’s been years and nothing changed regarding OpenStreetMap attribution from this company, but still “maps are at the centre”. Thanks @Strava & @Mapbox for your constant lack of respect towards our community’.

Software

• HeiGIT presented another ‘evolution-animation’ dealing with the development of mapped buildings in Nairobi using the ohsome API, in their blog post series ‘ohsome Region of the Month’. The blog post series provides information on potential applications of the ohsome API.
• raphaelmirc is introducing a road mapping tool in OpenStreetMap where it makes mapping in OSM very easy. The tool detects unmapped roads in OSM through artificial intelligence and makes life easier for the mapper.

Programming

• HeiGIT and the GIScience group at Heidelberg University are releasing the R code underlying their intrinsic data quality analysis of the completeness of the road network and health sites in Jakarta. The analysis is based on OSM data.
• As part of the Summer of Code, four people showed what they are working on to improve OpenStreetMap software:
  • Vuong Ho – Opening hours tag evaluator
  • Yash Srivastava – Interface for reporting search bugs for Nominatim
  • Antonin Jolivat – QA Reports Extraction Tool
  • Zohaib Ansari – Element History Widget
• Rob Grant, an open data specialist, explained how to access OpenStreetMap in R, a free programming language that allows you to analyse and visualise large datasets.

Releases

• HeiGIT and MapAction have announced two updates to the ohsome quality analyst (OQT). The new version 0.3.0 includes new OSM layers and a brand new data quality report with indicators about completeness and last edits. With this release it is now much easier to use OQT from your command line to calculate the data completeness for regions you are interested in. Starting now, OQT will also be improved publicly via GitHub, thereby improving collaboration with other researchers.
• Angel Cervera has released osm4scala version 1.0.8. osm4scala is a high-performance library and a Spark Connector used to read osm pbf files using Scala or Spark in any of its languages (Python, Scala, R, etc.)Two main improvements in this new release:
  • Added an ‘Info’ field. With this step, all fields are supported, even if they are not usually used.
  • New site with detailed documentation and examples at osm4scala site and documentation.
• Merkaartor 0.19.0-rc1has been released.

Did you know …

• … there is an OpenStreetMap based site, with correct attribution, displaying all air traffic?
• … what to consider when inventing new tags? Have a look at Jochen Topf’s guide from 2010 and Christoph Hormann’s recent additional suggestions.
• … it’s the one year anniversary of TafLeVelo’s project ‘Temps-velo’? The tool creates a network map from multiple OpenStreetMap based services, in order to give an overview of how much time is needed to cover a custom location by bike.
• … Waymarked Trails > ? A map that shows you all mapped routes on foot, by bike/MTB, on horseback, on inline skates and for winter sports?

OSM in the media

• M.P. Praveen, from the The Hindu, reported on the collaborative mapping of the local body wards of Kerala.

Other “geo” things

• The site ‘Lyon in 1700‘ offers a 3D reconstruction of a part of the city as it was at the beginning of the 18th century. It is the result of 10 years of work using numerous municipal and departmental archives and the collections of the municipal library. You can explore the city street by street and icons allow you to access additional information on the visible monuments. This first version is only available in French but an English version is under development.
• Eric Rogers from The Daily Californian reported that after after analysing OSM data PeopleForBikes found Berkeley to be the best mid-sized city in the US for cycling.

Android users will be required to download a new app for capturing images. On the upside, Mapillary is going to offer photo filtering based on their age, 3D scenes will be available to browse for all, and a new API has been introduced. To see all the changes visit the Mapillary blog.

Did you know …

• .. the ‘Priceless Map’ shows > you places (a table, a shelf, or a store) to drop off things and take or borrow them for free or cheap, such as amenity=give_box, shop=charity, shop=second_hand, or amenity=toy_library?

Other “geo” things

• With ‘Routago Assist’, Gerd Güldenpfennig and Stefan Siebert have presented > a pedestrian navigation system for the visually impaired or blind.

Mapping campaigns

• The Peruvian Space Agency (CONIDA), in coordination with other institutions, are organising the Mapathon 2021 > : ‘United in observations for the community management of disaster risk’ to be held from 28 June to 2 July, The aim is that participants improve geospatial data related to disaster risk management. The mapathon is part of bicentennial celebrations of the independence of Peru,
• The ‘Project of the Month Switzerland’ for June 2021 is / > about recording schools in OSM. There are helpful hints and links for this. Four charts show the changes to amenity=school | kindergarten | college | university over time.

Mapping

• [1] Voting is underway for the following proposals:
  • survey_point:structure=beacon/block/..., survey_point:datum_aligned=yes/no and survey_point:purpose=horizontal/vertical/both=* to tag the structure, condition, and purpose of a survey marker (until Sunday 4 July).
  • leisure=bathing_place to tag a place used for bathing and swimming, either official or informal. Mostly with an adjacent area to relax (until Tuesday 6 July).
  • building=fire_lookout and emergency=fire_lookout to tag fire lookouts (until Wednesday 7 July).
• Deane Kensok of Esri shared that historical versions of Esri World Imagery, called Esri Wayback Imagery, can also be used for mapping.
• User Heinz V lamented > that his efforts to encourage mappers to leave meaningful changeset comments in Nepal, rather than a string of hashtags, have had little effect. A broader analysis reveals that this issue occurs in edits across the world.
• Christopher Beddow speculated about how the level of community participation in OSM compares with proprietary maps from Silicon Valley firms, which, like Apple recently, often focus on detailed mapping of major tech hubs such as San Francisco.
• Voting on the following proposals has closed:
  • tourism=giant_furniture to tag any giant furniture meant to be a viewpoint or a tourism attraction was rejected with 9 votes for and 19 votes against.
  • man_made=stupa to substitute man_made=tower with tower:type=stupa was approved unanimously with 18 votes.

Community

• LittleMaps explored in detail the sealed and unsealed Australian roads in OpenStreetMap and reflected on the effort it took to get to where the map is now.
• lhirlimann shared > three blogposts from three districts of French Southern and Antarctic Lands, and express their amazement at the detailed mapping of some of these locations, such as the research base Alfred Faure on Île de la Possession in the Crozet Islands.
• OSM Fukushima (Japanese prefecture where SotM 2017 was held) mappers have published videos that talk about weeklyOSM and mapping topics.

OpenStreetMap Foundation

• The OSM Foundation is calling for volunteers to serve on a special committee to examine takeover protection.
• Guillaume Rischard, the treasurer of the OSM Foundation, has announced the Foundation’s possible move to the EU in a long email that is well worth reading. As was to be expected, the number of comments on this issue is extremely high.
• Board director Rory McCann belatedly summarised his OSM-related activities in March.

Local chapter news

• The OSM UK articles of association stipulate that two directors step down each year, and as they need a minimum of five directors to operate, they will have to appoint at least two new directors. Gareth gave more information here.
• The association of shopkeepers and craftsmen for the French town of Pontarlier have opened their data to OpenStreetMap. Information on its 500-ish members businesses is now fully integrated and up to date thanks to local group efforts. Monthly updates are planned.

Events

• The State of the Map 2021 Working Group is pleased to announce that the Conference Programme (9 to 11 July) is now available.
• Christoph Hormann (Imagico) previewed his State of the Map Q&A session on ‘Understanding the Map’. To assist in this he has set up a wiki page to collect examples suitable for discussion. The same information is also available on an etherpad.

Education

• A workshop, held by the Erasmus+ project euYoutH_OSM, explains step-by-step how to use uMap to create a map that shows locations of schools along with pictures of the schools, links to the schools’ websites, their phone numbers and social media links. This is an excellent example for developing your own projects.

Maps

• Amazon talked with Thomas Rosen about QueerMap, an OSM based LGBTQ+ map.
• AnyGIS (as we reported earlier) provides links to bulk download raster tiles from online maps for various apps. Not only is bulk downloading prohibited by some map providers, the maps packages provided by AnyGIS allow Locus to do so by faking user-agent and referrer headers in the requests Locus sends to map providers.
• Nicolelaine wrote about the possibilities of displaying post offices and postboxes using uMap and the Overpass API.
• Tomas Straupis highlighted an open source version of the Wang–Müller algorithm developed by Motiejus Jakštys. The algorithm tries to generalise lines according to cartographic requirements, such as saving or even exaggerating characteristic features.

Software

• French group Linux Alpes is hosting an instance of OSM24 covering South Eastern France. The application aims to display opening hours of different POIs using current OpenStreetMap data.
• The ‘Plastic Tracker’ is a tool to illustrate the fate of floating plastic 20 years from now, should you lose it today from your location or anywhere else in the world. Where will it go? How probable is it that it will reach the ocean? This tool will give you a possible answer to these questions and shows how far plastic can travel from its starting point.

Did you know …

• … the 15-minute city map? It shows > at a glance where in a German city residents are able to meet most of their needs within a short walk or bicycle ride from their homes.
• … there is a map that shows the river > basins and watersheds of Central Europe?
• … Röntgen? Started in September 2020 by enzet, it aims to be a simple renderer for OpenStreetMap with custom icons intended to display as many tags as possible.
• … Cycle Travel? It helps find the best and safest cycling routes in Europe, the USA, Australia and New Zealand. The next update features routes which avoid busy roads in many of these countries.

OSM in the media

• Thierry Jean is co-founder and president of the AddressForAll Institute, a collaborative, open and free database that aims to collect addresses. In this interview with Geocracia, he explains > why the best way to do this is through platforms like AddressForAll and OpenStreetMap.
• Top Gear’s Philippines site informed us about the progress of the project to improve the mapping of Manila’s bicycle routes in OpenStreetMap.

Other “geo” things

• Nicolas Ottersbach described > the status of the creation of a digital 3-D twin of the city of Bonn.
• Allen Downey spotted a very unusual colour ramp on a map used to illustrate a Washington Post article. One of the comments in the thread provides some explanation of its purpose: apparently this is to pick out a range of different cloud-top weather phenomena.

Mapping campaigns

• CartONG hosted an online bilingual (FR/EN) mapathon on World Refugee Day on 21 June to map refugee locations. This event was organised jointly with MAMAPA, HuMap Trier and OSM Ghana.

Mapping

• Wille Marcel produced some statistics about the usage of different editors in each region of the world over the past 10 years. He also provided some insights based on the data.
• James Pain detailed what he has been mapping in the Riverside Estate, Colchester (England).
• User Mapman029 has been concentrating their mapping on features which are likely to represent ecological corridors. Whilst doing so they remarked >
  on how few hedges have been mapped in Brittany, and invited others to join in rectifying this omission on OSM.
• fanfouer’s proposal on substation=*, to improve power substations and transformers mixing on the same node for small substations, awaits comments.
• Pascal Neis introduced two quality assurance features to ‘How did you contribute to OpenStreetMap?‘ profiles. They now contain some information about the user’s reverted map edits and rollbacks carried out by the user. Pascal is asking for feedback.
• Veniamin Veselovsky wrote a blog post on ‘An Automated Approach to Identifying Corporate Editing Activity’.

Community

• As part of the Everywhere She Maps program, YouthMappers is launching an internship match program. This will help organisations match qualified YouthMappers students who identify as women and/or non-binary with internship opportunities. Details are contained in a Google Document.
• Jerry Clough (OSM user SK53) marked the 10th anniversary of the East Midlands local group (UK) with some remarks about the group and their meetings.
• Pedro Tharg described > his personal journey to becoming an OSM mapper.
• Rob Nickerson, from OSMUK, explained how 27 million addresses in the UK could be opened up using two existing open datasets and deriving address centroids, which can then be used for mapping (e.g., using MapComplete).
• Robhubi wrote > about why he is turning away from Mapillary and towards Kartaview (formerly OpenStreetCam).

OpenStreetMap Foundation

• Mikel Maron invited people who are part of a local chapter or a local community, putting together an organised project or developing software, to present it at an OSMF Board meeting.
• Christoph Hormann described, in great detail the ‘good and bad things’ in the OSMF’s draft of the new attribution guidelines. The phrase ‘a few words’ in the title is no doubt intended ironically, after all there are more than 3,600 of them ;-).
• One of the OSMF Board members has changed her name to Amanda McCann.

Local chapter news

• FOSS4G/SotM Oceania are having a logo contest for their joint 2021 conference.
• Jess Beutler, of OSM-US, provided advice on how OSM mapping can help emergency responders. Although the advice is pitched at US mappers, much is probably just as salient elsewhere. There are also a couple of examples of the direct benefits of using OSM in these situations.

Events

• State of the Map 2021 is taking place online from 9 to 11 July. Here are the programmes for:
  • Friday
  • Saturday
  • Sunday
  • Also check out the academic tracks.

  SotM 2021 is present on Twitter and Youtube.

• From 19 to 21 September, FOSS4G-IT 2021 > will be held online, organised by GFOSS.it and Wikimedia Italia.
• Charles Millet and Antoine Riche, from the French association Mieux se Déplacer à Bicyclette, organised > a bicycle parking themed two-day mapping party. Through the weekend, four hundred locations were added to OpenStreetMap and more than a hundred notes are still pending.
• Ilya Zveryev provided an overview > of State of the Map for Russian speakers.

OSM research

• The team at HeiGIT has written a walkthrough on how to train your own building detector using ohsome2label and the TensorFlow Object Detection API. You can find all the necessary scripts and detailed walkthrough tutorials in the GitHub repo.
• Users of the MeinGrün App in Dresden and Heidelberg are being asked one last time to take part in a survey and provide information for possible future development. On 28 June, HeiGIT and their research partners in Dresden, will present the results of the research > and the meinGrün web portal at the Dresden Land Use Symposium (DFNS). The app is based on OSM data.
• The team at HeiGIT has published a tutorial on how to analyse which country has the longest coastline, using OSM data. They used the ohsome platform, which makes OpenStreetMap’s full-history data more easily accessible for various kinds of OSM data analytics tasks.

Humanitarian OSM

• The research team at HeiGIT has analysed mapping collaborations between humanitarian organisations and corporations using Humanitarian OSM Stats, which combines data from the Tasking Manager, hosted by the Humanitarian OpenStreetMap Team, and ohsome OSM History Data Analytics Platform. The results show that Aviva mappers have added more than 297,800 buildings and 8,320 km of roads to OSM since 2015.

Maps

• Randall Munroe’s xkcd cartoon featured a map of US placenames easily confused with better known places.

switch2OSM

• Neuland21 is in the process of creating a ‘forest fire app‘ > to help Brandenburg fire departments fight forest fires.

Licences

• Peter Wells, formerly of the UK Open Data Institute, raised some interesting points on sui generis database rights and the EU Data Act. In the Twitter thread he points to a consultation response by Paul-Olivier Dehaye, which raises issues regarding copyleft licences such as ODbL. Dehaye notes that OpenStreetMap have not responded to the CEC consultation.

Software

• [1] NL Maps provides a natural language interface to search OSM. It’s already been tested by Jez Nicholson (director of OSMUK) and Allan Mustard (chair OSMF)
• Miroslav Suchý created a script, greeter-osm, that sends greeting messages to new users in your region or country. It utilises Pascal Neis’s Latest OSM Contributors feed. The script is fully configurable using a config file and made to be run as a cron job. An Ansible role for easier deployment is provided. greeter-osm is based on a similar non-public script from the Slovak OSM community.
• After a test run, user Escallic recommends mapping curved features by tracing with a mouse or a suitable touch gesture. To enable this they have released an open source patch for the iD editor. To avoid overloading drag operations this is enabled in-editor as a distinct mode.
• Tom MacWright promises that Placemark will be the fast and powerful way to edit geospatial data.

Programming

• The Regionalverband Ruhr has used the potential of HeiGIT’s openrouteservice (ORS) in a new QGIS extension. The tool, ‘Location and Route Optimisation of Addresses’, allows you to search and locate addresses and to find the optimal routes between them.
• Matija Nalis has recently implemented RSS feeds to announce when the weekly created BitTorrent files (in total 428 GB) of the complete OpenStreetMap data are available to download.
• CycleStreets have released an R package to interface with their routing API. Routes are returned with extensive metadata and, as with any client, access requires an API key.

Releases

• The current version of QGIS (QGIS 3.20.0 ‘Odense’) was released on 18 June and is named after the third largest city in Denmark. This version has a number of data management improvements including basic support for coordinate epochs of dynamic reference systems. For a description of the other changes made you can read the change log.

Did you know …

• … CyclOSM? This is one of two bicycle maps featured as layers on the main OSM site.
• … Anvaka has made a tool to render a map of all the streets of a city, in a free selectable two colour mode? The result can be saved for other purposes, such as printing on a mug.
• … Erick De Oliveira Leal has a tutorial on using the Strava high resolution layer for OpenStreetMap (JOSM or iD)?
• … the broad spectrum of services provided by the Heidelberg Institute for Geoinformation Technology (HeiGIT) in the form of technologies, projects and case studies?

OSM in the media

• Techtimes presented the best Google Maps alternatives from a privacy perspective. Of course, OSM is number one.

Other “geo” things

• The Guardian took a look at Cool Walks, which maps shady spots to guide Barcelona walkers along cooler routes. Cool Walks aims to help pedestrians avoid dangerous heat and find public drinking fountains. Last year we reported on a similar service for Heidelberg and Dresden.

Breaking news

• Kai, an active mapper with disaster management expertise, shares his urgent recommendations for mapping the impact of the flooding in western Germany which happened earlier this week on 15th and 16th July.

About us

• Erratum: The StreetCompleteness web interface that lists the completion percentage for some selected StreetComplete quests (we reported last week) was not created by Tobias Zwick, who created the StreetComplete app, but by Wieland Breitfeld > . We apologise for the error.
• Good news: Our Korean contributor and translator, Donga Hwang aka LuxuryCoop is back from his co-literary duty (doing military service with the Air Force) and therefore our Korean edition has been back since last week.

Mapping campaigns

• TomTom have created five MapRoulette challenges aimed at checking and improving OSM for vehicle navigation. Each challenge covers a different part of Africa, and TomTom indicates that they are based on both regular OSM quality control tools, such as Osmose, and data and validations internal to TomTom. No details have been provided about how to modify the tagging.
• Edoardo Neerhut announced on talk-au that OSGeo Oceania has allocated $2,500 AUD funding specifically for OpenStreetMap-related initiatives.
• The Swiss OSM Association’s July Project of the Month is targetted at data improvement of campsites and overnight sites for recreational vehicles (RVs or motorhomes). Detailed instructions are available on the wiki ( or ).
• [1] The third UK Quarterly Project of 2021 is focused on tourism: facilities and areas of interest for visitors, such as hotels, caravan parks, public transport hubs, public footpaths, and places with historic interest.

Mapping

• Naming the Schneeberg, an Austrian mountain, has turned out >
  to be controversial. It is a steep-sided undulating limestone plateau with several summits (see this old account of other aspects of mapping in the area). The problem is that there is apparently no good way to name the whole range on OSM, and therefore some have advocated either using the name for the highest peak or appending the name of the range to the peak ‘Klosterwappen (Schneeberg)’.
• AngocA outlined > his views on and experience with OSM notes in a detailed diary post.
• PkBuzios blogged about his mapping progress at the Seale-Hayne campus, located in Devon, UK. The campus was purpose-built as an agricultural college about 100 years ago, and was later a campus of the University of Plymouth until teaching stopped in the 2000s.
• [1] Requests have been made for comments on the following proposals:
  • defensive_structure=* for tagging defensive structures at all modern and historic fortifications.
  • man_made=video_wall for mapping large digital screens.
  • barrier=cycle_barrier to extend the tagging for cycle barriers in order to determine the passibility of these kind of barriers for different vehicle types, especially cargo bikes, bikes with trailers or wheelchairs.
• Voting on the following proposals has closed:
  • leisure=bathing_place, to tag a place used for bathing and swimming, was not successful with 8 votes for, 9 votes against and 3 abstentions.
  • building=fire_lookout and emergency=fire_lookout, to tag fire lookouts, was approved with 21 votes for, 2 votes against and 1 abstention.
  • The survey marker proposal to tag the structure, condition, and purpose of a survey marker, was approved with 13 votes for, 2 votes against and 5 abstentions.

Community

• Amanda McCann last week released her ‘activity reports’ for April, May and June.
• The OSM Iran community mourns [fa]
  a young contributor, Mohammed Reza Norouzi. (Translation is available on Twitter.)

OpenStreetMap Foundation

• The Engineering Working Group is restarting with a new charter. Mikel Maron distributed a draft of the proposed charter and the OSMF is seeking feedback.

Events

• Martijn van Exel reported about State of the Map 2021 from the perspective of task-based editors and MapRoulette.

OSM research

• Oliver Fritz noted that the 2021 AGIT symposium > has accepted a new paper by a HeiGIT research team. The paper discusses a different approach to the global analysis of OSM data completeness. This is accomplished by generating reference data from demographic and socio-economic indicators, as well as sporadically available open General Transport Feed Specification (GTFS) datasets via a regression model.
• Linda Sendlinger reported on a publication by Yeboah et al. concerning the analysis of OSM data quality for different stages of the mapping process in slums. The authors have developed four novel definitions of completeness based on the total number, length, and area of OSM objects. All definitions were formed at arbitrary timestamps, allowing for these objects to be assessed for completeness at any time during the mapping process, as well as the estimation of potential disparities.
• Michael Szell and colleagues used OpenStreetMap data to explore the limitations of different urban bicycle network models’ growth before rendering them.

Humanitarian OSM

• Spatial Collective, Humanitarian OpenStreetMap Team, and OpenMap Development Tanzania facilitated a final workshop with key government officials to share the methodology, collected data, and had discussions on how they can use the data for disaster management and risk reduction in Ilemela and Nyamagana. The aim was to ensure that they have the data collected, update and add more data according to their needs by using free and open-source software and other cost-effective tools used in data collection.
• Seven OSM communities in Tanzania have been selected to receive OpenMap Development Tanzania Community Impact Microgrants.
• OpenMap Development Tanzania recently held their first workshop for potential ‘Open Skies Fellows‘ candidates. Sixteen people from different regions of mainland Tanzania and Zanzibar attended. The candidates were exposed to different technologies including drones and 3D printing. They learned how to assemble 3D printers and design, assemble and fly drones, as well as plan drone missions.
• HeiGIT, TdLab Geography and the GIScience Research Group at Heidelberg University are collaborating on the transdisciplinary HEAL project which supports people, especially at-risk groups, during heat waves. This is accomplished by involving target groups and stakeholders, as well as by integrating public smart city data into a routing system.

Open Data

• Geoalert, a startup, published an Open Urban Mapping update using new Mapbox satellite imagery, which is aimed at contributing to OSM. The number of extracted building footprints increased by x2.5. They explain why why Chechnya is the most poorly mapped among all the regions of Russia.

Software

• AntoJvlt gave a few insights into his Google Summer of Code project ‘Nominatim QA Analyser Tool’, capable of analysing Nominatim’s database to extract suspicious data from it and presenting the results in a graphical interface so they can be corrected.
• Baato announced the beta release of a tool to compare OSM mapping of a particular area at two different times, thus facilitating before–after comparisons.
• The Android app GeoNotes creator, hauke-stieler, gets feedback from time to time and they have made some changes. Among other things, the export to GeoJSON, a list of all notes and a feedback option via email for non-GitHub users have been added.
• goodudetheboy gave an update on the progress of the OpeningHoursEvaluator and also an outlook for the next steps.

Mapping

• Mappers in the German OSM Forum > and on the Talk-de mailing list > discussed how to deal with the floods in Western Germany. Damaged roads which will stay impassible for a longer time should be tagged as under construction or demolished. Buildings should not be edited/deleted for the time being. Road closures for a relatively short time and closures of passable roads should not be mapped.
• Mark Altaweel took a look at map vandalism in OpenStreetMap. They describe what map vandalism is and what strategies are used to fix it or prevent it from happening.
• If you map in Washington state it would be worthwhile reading jake-low’s diary entry on how to use the Department of Natural Resources LiDAR in iD.
• MKnight questioned > some of the reasons given for voting against the leisure=bathing_place proposal (we reported earlier).
• Philippe Lacour noted that there are now more objects in OpenStreetMap than people on the planet.
• portalaventura asked > why Apple editors feel the need to bend streets.
• User syntex shared a progress update on his quest to replace all the mapped buildings in Warsaw with outlines from a government dataset, BDOT10k.
• Requests have been made for comments on the following proposals:
  • cultivated=no/semi/fully to add sub-tags to natural=scrub that could be used to further refine these bushy areas based on objective criteria.
  • tennis=wall to map tennis training walls, used to practise tennis shots without the need for an opponent.
  • headlight=* for tagging when vehicle headlights must be used.

Community

• How many hours a day do you map? Jennings Anderson investigated how much time mappers spend on the task and concluded that while some mappers might only ever make a single edit to a map, there are plenty of ardent, dedicated editors that map like it’s their job – and for some of these mappers it might be, but definitely not all.
• Nama wrote, as Regional Director of HOT, about the foundation and activities of the (Mobile) Open Mapping Hub Asia Pacifik.

OpenStreetMap Foundation

• To reduce mass downloads from tile.openstreetmap.org, in violation of the tile usage policy, the Operations Working Group has put an automatic block that filters the 0.001% users who cause 13% of the load.

Events

• DeBigC reviewed the format of this year’s State of the Map. They concluded that, on balance, the interesting talk content and speakers outshone the weaker points.

Breaking news

• [1] Quick, get your act together! As we go to press the OSM 17th birthday global mapathon will be underway. The mapathon starts at 03:00 UTC (13:00 Australian Eastern Standard Time) on Sunday 8 August with the OSGeo Oceania community. A different OSM chapter takes the lead each hour until 19:00 UTC (12:00 PDT; 17:00 EDT) when OSM US concludes the mapathon. Most communities have chosen thematic mapping activities.

Mapping campaigns

• MoiraPrime pointed out, on the talk-us list, that the Amazon corporate mappers are now working on college and university campuses across the US. They appear to be making extensive use of existing campus maps, which may or may not be compatible with OSM.
• Eiim set out their ambitious plans for mapping Oxford, Ohio.
• OSM US are working to map playgrounds in Philadelphia. The project is a collaboration with KABOOM!, a not-for-profit devoted to improving access to playgrounds for poorer children.
• OSM Uganda is joining with Nairobi-based social enterprise Upande to collect map data related to agriculture and food security.

Mapping

• Frederik Ramm from the Data Working Group highlighted that automatic problem fixing can be considered to be an automated edit, and therefore subject to the automated edits policy. Andy Townsend, also from the DWG, provided an example of the type of issue that DWG is finding when contributors apply ‘tag fixes’ suggested by editors inappropriately.
• AngocA continued > his series of diary posts on OSM Notes with advice about how to post a note in various applications and websites. The advice focuses particularly on people wishing to have their business mapped on OSM.
• Another numeric milestone surpassed, user gpserror reported that the USA now contains over 1 billion nodes.
• The proposal foraging=* to indicate whether or not foraging for plants/fruit/fungi etc. is permissible for a given location or plant is open for comments.
• The following proposals are waiting for your vote:
  • cycle_barrier=*, cycle_barrier:installation=*, corners=*, deflection=*, spacing=*, opening=* and overlap=* to indicate type, design, size and width specifications for cycle barriers – i.e. barriers along a path that slow or prevent access for bicycle users. Voting is open until Monday 16 August.
  • maintained=no/yes/rarely/semi/intense to indicate how maintained a natural feature is. It is initially meant for mapping shrubbery as natural=scrub but can be used on any natural feature. Voting is open until Tuesday 17 August.
• User SK53 blogged about two unusual pavement (sidewalk) features: deterrent paving and perforated kerbs. The former is difficult to walk or drive over; the latter helps to improve surface water drainage.
• User SK53 also provided some detailed notes on tactile paving used in the United Kingdom, and recommends using them to estimate widths of crossings and pavements (sidewalks).
• Simon Poole reported > that orthophotos from the SwissTopo geoportal are now available directly in the iD editor. Previously these needed to entered as a custom layer.

Community

• Dongha Hwang has created > a Facebook page for the Korean OSM community.
• OpenStreetMap Belgium’s Mapper of the Month for August is Mishari Muqbil (Mishari) from Thailand.
• OSM US has published its latest monthly newsletter, for July 2021.

OpenStreetMap Foundation

• Allan Mustard, chair of OSM Foundation, requested for feedback to help flesh out the draft Strategic Plan for the foundation.
• User pnorman summarised his recent SotM 2021 presentation on the OpenStreetMap Standard Layer and who is using it.

Open Data

• Google Research Ghana has released the OpenBuilding dataset. The open dataset contains 516 million buildings, across an area of 19.4 million km² (64% of the African continent). The data are licensed with the Creative Commons Attribution 4.0 licence, which is not directly compatible with OSM.

Licences

• OpenStreetMap France tweeted that more than 10,000 websites have integrated maps that use OSM data. For domains using such maps without attribution, of which there are over 200, a special tile is served partially replacing some map tiles.

Software

• Mapswipe announced a new release including updated translations in various languages. Italian is newly supported.
• WhatOSM outlined > some developing issues with using WGS84 as a baseline for geodata, some of which we have reported earlier. These are most acute for objects located on the Australian tectonic plate which has moved 1.8 m relative to the original specification but applies elsewhere too. Most geosoftware, and data formats, including OSM, make inadequate provision for the best way to handle WGS84 coordinates, the use of epochs. For many uses, the best practice is to use a local coordinate system unaffected by plate tectonic shifts.

Programming

• User SomeoneElse shows you how to programme a watchdog for changes to long-distance paths on OpenStreetMap.

Did you know …

• … of the detailed map of roads throughout the Roman Empire? Known as the Tabula Peutingeriana, the existing source is a 13th century parchment map, but internal evidence, such as the presence of Pompeii, suggests the original source was compiled in the 1st century CE.

OSM in the media

• The New York Times analysed how governments and other organisations have used geospatial data to plan COVID-19 vaccination campaigns (paywall). The article mentions a range of other purposes in using geodata and GIS during the COVID-19 pandemic by US authorities. In less-developed nations, it also features the joint mapping initiative of, amongst others, Alcis, CartONG, HOT, iMMAP and MapAction, ‘Geographic Information Management Initiative for COVID-19 Vaccine Delivery’.
• Esquire Philippines dove deep to look at the activities of Mapbeks in providing mapping of LGBTQI+ spaces using OSM data. The article provides detailed background on three of these: the LGBT Safe Spaces Map, HIV Facilities and Support Map, and Mapbeks Stories Map.

Other “geo” things

• Twitter user RevK reported that an emergency service in England is only accepting postcodes or what3words locations.

About us

• Mariotomo, from Panama, explained some of the problems faced by our readers in countries with poor and/or expensive internet connections. He has a relatively simple solution: using a bash script to pull items from the RSS feed which may be of interest to others.The weeklyOSM team are interested to hear of similar issues or solutions. Our aim is to reach as many as possible in the broad OpenStreetMap community wherever they are.

Mapping

• TomTom has introduced a new QA tool. The announcement coincided with OSM’s 17th anniversary.
• Reddit user midforty asked, on the OSM subreddit, about mapping unofficial hiking trails. They had mapped one which someone else had then deleted. Various opinions are expressed about whether this is good practice or not in the comments.
• Requests have been made for comments on the following proposals:
  • catholic=* for a more precise tagging of the Catholic denomination.
  • transformer=* for refining power transformers classification.

Community

• You are invited to upload photos from various OSM 17th birthday parties to the wiki.

Imports

• Kirill Setdekov posted on the OSMF-talk mailing list hoping to make a request to import Google’s Open Buildings for Africa into OSM. The post met strong opposition by mappers in several African communities who deemed that the building footprints were of low quality and would only exacerbate poor quality edits in the region.

Events

• [1] Arnalie reflected on how State of the Map worked from the perspective of an organiser, and made some recommendations for future online only events.

OSM research

• Researchers from HeiGIT have studied the impact of large data imports on OpenStreetMap by comparing contributor activity both when imports are active and when they are paused.

Maps

• RobJN recently created an MVT (Mapbox Vector Tile) layer of property data (UPRNs) in Great Britain, but many labels were duplicated. In his latest post he describes how he overcame this issue by styling the layer in JOSM. The general principles are more widely applicable to other MVT layers.

switch2OSM

• Niceboard posted on Hackernoon explaining why they switched from Google Places to Mapbox for their Autocomplete API.

Software

• José Juan Montes showcased the DDD project’s capabilities in generating and showing 3D scenery built from OpenStreetMap data.
• Felix Delattre has announced a new version of mod_tile and renderd (to generate raster tile images and deliver them via a web server). At the same time the software packages have just became available in the official sources of the brand new stable Debian 11 (bullseye) and Ubuntu 21.04 (hirsute).

Releases

• The Android version of OsmAnd 4.0 has been released. This version offers cloud backup, the ability to colour tracks by altitude, speed or slope, and other interesting new features. Note that this release introduces new subscription models.

Did you know …

• … you can easily extract administrative boundaries such as country, state and regional borders or equivalents from OpenStreetMap using OSM-Boundaries?
• … of the South-pointing chariot (our historical map-related item of the week)? A Chinese invention which used a mechanism to take movement of the chariot’s wheels and ensure a pointing device was always oriented to the south.

OSM in the media

• Bloomberg CityLab reported on HOT’s various projects for mapping informal settlements (slums) in less-developed nations.

Other “geo” things

• This week OpenCage’s geo weirdness thread returns to Europe to take a look at Belgium.
• Whilst doing some mapping in the London suburb of Mill Hill, SK53 noticed roads named after famous scientists with one female (given) name amongst the (male) surnames.
• Bloomberg reported that the attempt to establish a union at Mapbox failed. Although more than half of the voting employees had become union members, Mapbox opted to exercise their legal option to force an additional ballot. A majority of those voting in this ballot did not support union recognition.
• Matt Parilla asked the rhetorical question ‘why does sunlight come from the north in shaded relief maps?’. He shows in the answering thread that it is related to how the human brain interprets light and shade to detect objects in three dimensions.

10/08/2021-16/08/2021

Mapping

• A long thread on how to tag recreational routes designed for multiple transport modes led Kevin Kenny to suggest that striving for a Platonic ideal of tagging is not necessary.
• oh8mxl wrote a blog post about ‘how to check cycling mapping mistakes and fixme tags in your area’.
• Requests have been made for comments on the following proposals:
  • A new role ‘transfer’ for recreational route relations. There is no wiki page but you can find the mail list thread here.
  • cadet=military for mapping the meeting place of a local military cadet unit.
  • club=cadet for mapping the meeting place of a local youth cadet group.
• Voting is underway for the following proposal:
  • man_made=video_wall for mapping large digital screens (till Monday 23 August).
• Voting has ended for the following proposals:
  • cultivated=no/semi/fully to add sub-tags to natural=scrub was unsuccessful with 25 votes for, 18 votes against and 2 abstentions.
  • barrier=cycle_barrier to extend the tagging for cycle barriers was approved with 31 votes for, 2 votes against and 0 abstentions.

Community

• OSMF Board member Amanda is now up-to-date with their activity report for the month of July.
• Discussions about using Discourse to replace the OSM forum have been happening
  for some time. The French community has migrated their forum from phpBB to Discourse and also migrated > all the existing posts from the old system. On the German forum, the question is raised > how to deal with old posts (for example: NL > 60,000, RU > 260,000 and DE > 300,000) when migrating from https://forum.openstreetmap.org.
• User mariotomo took a detailed look at the projects hosted on the HOT Tasking Manager, gathering statistics on how many have been started, how many have finished, and how long they have been active.

Imports

• In an email from MSF, GIS officer Roxana Nazarie outlined a planned way to share non-sensitive data collected and approved by field teams with OSM. The context is that the import process is too long-winded when data needs to be shared for a rapid response. Most replies suggested that the proposed method was an import anyway, and a number of other approaches were suggested.
• Attila Kun and Brian Sperlongano are proposing an import of West Virginia State Forests.

OpenStreetMap Foundation

• The draft Etiquette Guidelines, proposed by the Local Chapters and Communities Working Group Moderation Subcommittee, are open for comments until Wednesday 8 September. They will apply to the talk and osmf-talk mailing lists. However, the authors recommend applying them to all OSMF-run platforms (forum, wiki, and national mailing lists) as well. Comments can be written and reviewed on the discussion page.

Maps

• In the streetscape map of Neukölln you can see how streets, sidewalks and street-side parking can be represented with OSM data. Tobias Jordans describes > in his blog post which data is visualised and where it comes from.
• Dirk Brockmann invited people who want a global view of the COVID-19 situation to check out this visualisation.
• Ashley Pinner and Harry Wood discussed, on Twitter, how various OSM maps show railway platforms.

Open Data

• Since 2018 the UK government has been lavishly funding the Geospatial Commission, or at least their contractors: predominantly, management consultancies. It is therefore somewhat of a surprise that their recently published list of geospatial data from trustworthy organisations seems to have lots of gaps. Peter Wells spotted, that the report not only fails to mention OSM at all, but deems that there is no authoritative source of addresses for most of the country.

Licences

• สุทธิสาร ปานสัสดี reflects > on a wide variety of licensing options in the context of OSM. He asks for feedback.

Software

• Yash Srivastava gave a final update, illustrated with screenshots, about his Google Summer of Code Project. The Nominatim Feedback Reporter will allow users to submit OpenStreetMap search (Nominatim) errors. These can then be added as test cases by the developers.
• [1] User mmd demonstrated how a query to count addr:housenumber nodes across all EU member states, broken down by country, will run in 30 seconds on an Overpass development branch version. ATTENTION: The same query will not run on current production versions.
• OrganicMaps (an OSM-based mobile app) has started a donation campaign to help pay for servers and fund development.

Programming

• User mahdi1234 published a short article on building a Matrix chatbot to report statistics from taginfo in the Czech community channel #osmcz:matrix.org.

Did you know …

• … about the Swiss cartographer Eduard Imhof? Our historical map-related item of the week. He was a pioneer of creating maps with shaded relief (as aspect of which we featured last week), and author of an influential text book. He also created, with skilled technical assistants, a number of large scale relief models, some of which can be seen in the Swiss Alpine Museum in Bern.
• … you can keep up to date with the happenings in the OSM software world with Walter Nordmann’s software watchlist?
• … about Pascal’s website Unmapped Places? This tool shows place tags that don’t have a road within 700 m of them, suggesting the presence of an unmapped settlement.

Mapping campaigns

• Congrats to Mapbeks and Youthmappers for their successful mapathon competition for a cause (map for sustainability), where they mapped 41,994 buildings in five days. To celebrate, 280 trees will soon be planted in the #OpenStreetMapPH Forest in Zamboanga del Norte.

Mapping

• Anim Mouse noticed a changeset that spans four continents and contains only a single change. Although it was pointed out in the discussion that a changeset should contain as small an area as possible, sometimes it is not possible when the element itself is very large, in this case France, including its overseas territories and départements.
• Bora Can wrote > about his efforts to clear up divergent district boundaries in Turkey.
• Russ Garrett summarised his thoughts on how various recently released government open datasets might be used to improve address mapping the UK.

Community

• State of the Map Africa 2021 is happening online on 19 to 21 November. Listen to the July episode of the Geospatially podcast, featuring Geoffrey Kateregga who discussed SotM Africa and how they will bring OSM communities in Africa together.
• Manoj, Ark, and Awantika took a look at the history of OSM Kerala and its continued efforts to strengthen the use of OSM in Kerala (India) for disaster response and community development.
• One has learnt that Christoph Hormann’s ‘couple of words’ tend to be a bit longer than the phrase implies. His theme discussed this time is the implications of the draft OSMF Etiquette Guidelines. Although a DeepL translation to English is provided, he emphasises that this will lack nuances of the original German text: an issue which he feels affects any contributor needing to use English when it is not their native language.

OpenStreetMap Foundation

• weeklyOSM strives to notify you, our readers, about upcoming OSMF board meetings. Unfortunately, at present announcements of upcoming meetings are being made within a week of the meeting, so it is not possible for us to announce them accordingly. If you are interested in the public board meetings, you should follow the OSMF mailing list, subscribe to the Board’s iCalendar feed, or keep an eye out for them in our Upcoming Events section.
• Former OSMF Board member Peter Barth expressed his concern about the attribution of OSM on maps provided through Mapbox services.

Events

• The Community Working Group (Humanitarian Open Mapping) organised by HOT invites local OSM community organisers, leaders and members (new and old) to come together and share their tips, tricks and challenges related to starting and sustaining local OSM communities. Two Zoom meetings will be held on Friday 3 September at 06:00 UTC and 16:00 UTC. Register if you wish to participate.

Humanitarian OSM

• HeiGIT is working on routing that incorporates current data from disaster areas, such as areas subject to flooding or destroyed streets. To help with the current flood disaster in Germany and neighbouring countries, HeiGIT has taken up-to-date flood data derived from satellite images by the European Copernicus Emergency Mapping Service (EMS) and integrated them into the routing services developed by HeiGIT.
• In mid-August HOT, in collaboration with local communities in the respective regions, activated two disaster response campaigns: Haiti Earthquake 2021 and Mediterranean Fires 2021. You can check the updates here and see other active responses.
• The Humanitarian OpenstreetMap Team (HOT) Summit 2021 Call for Proposals has been extended. The new deadline is Tuesday 31 August.
• The finals of the 2021 HOT Staff OSM FIGHT Heavyweight Championship were held at a recent HOT all staff meeting.

Maps

• [1] Ever wondered how old that building in Penza (Russia) is? Then this is the website for you. In addition to OSM, data from wikivoyage, wikidata and wikimapia, among others, have been used.
• Nicolelaine is still having trouble getting their uMap of world post boxes to work, due to Overpass timeouts. Any help would be appreciated.
• PlayzinhoAgro shared > the results of a survey of online map use and knowledge of OpenStreetMap in Brazil.

Software

• Recently we covered the KGeoTag application. There is a similar application called geotagging, a tool for manipulating the geographical information stored in JPEG images (Exif metadata). The geographical information could be obtained from GPX or manually by drag-and-drop. The application is packaged as an EXE or as a flatpak. Feel free to contribute translations or code.
• Trufi’s OSM-powered bike app will put bikes at the centre of multi-modal journeys like no other app. The app will launch in Hamburg at the ITS World Conference.

Programming

• The final reports for projects that were part of the 2021 Google Summer of Code are in:
  • Vuong Ho’s opening hours tag evaluator
  • Zohaib Ansari’s stand-alone library to display multiple versions of any selected OSM element and allow comparison between different versions
  • Antonin Jolivat’s Nominatim QA reports extraction tool.

Did you know …

• … The Panorama of the River Thames? This is a website which shows panoramic views of parts of the River Thames through Greater London both from watercolours of 1829 and photographs from the present day.
• … that you can use OSM Smart Menu in Google Chrome or Mozilla Firefox to open links related to OpenStreetMap, based on parameters from the current page? It helps OpenStreetMap contributors to easily switch between different maps and analysis tools.
• … that LearnOSM is dedicated to helping people learn how to map in OpenStreetMap? The guides start from the basics of what OSM is and how to get mapping, through to advanced topics such as osm2pgsql and manipulating data with Osmosis.
• … you can check out who is the busiest on MapRoulette by viewing the leaderboard?

OSM in the media

• Woxx carried a couple of articles on OpenStreetMap. The first > is an introduction to OpenStreetMap and features an interview with OSMF Board member Guillaume Rischard. The second > article describes to readers a number of ways that they can also participate in OpenStreetMap.

Other “geo” things

• Médecins Sans Frontières (MSF) is seeking a Geographical Information Systems Advisor. Based preferably in Amsterdam, Berlin, London, or Nairobi. Other locations where MSF has offices will also be considered.

• The OSM-US project to map playgrounds in Philadelphia (we reported earlier) was completed on 1 September.

Mapping

• Jeroen Hoek noticed a page on the wiki relating to a proposal to regularise the tag china_population. The tag seems to designed to change the way some larger cities in China are rendered.
• The authorities of the French commune of Torsac have recently completed a project to name streets and assign house numbers. Wilfried, a commune representative, asked , on the OSM-FR forum, why these addresses and street names do not yet appear in OSM. The answer turned out to be somewhat complex, as the long thread in the forum shows. However, the issue was resolved by Christian Quest.
• Andrés (User AngocA) from Bogotá explained > in a diary entry how to analyse Notes and how, if there are many Notes open in the area of interest, you can develop a strategy to close them.
• [1] User Lejun has written up some interesting tips for mapping individual parking spaces.
• Monika Tota asked members of the OpenStreetMap Polska group how they tag properties that are somewhat subjective, like smoothness=good vs intermediate or wheelchair=yes vs limited. People responded with many methodologies they use, pointing out that reality often resists clear-cut classification and that this question is related to the issue of cartographic generalisation.
• Voting is open until Sunday 19 September for the proposal club=cadet, intended to be used to map the locations where various Youth Cadet groups meet, together with details of each group.

Community

• User Assange expressed their dismay at mapping changes in China and Taiwan which they perceive to be politically driven. For example, is this a vacation school or concentration camp?

• Tif.hair used > data from the French national statistical institute, INSEE, in order to map 4,000 hairdressers in France with, mostly bad, puns in their names. While using OpenStreetMap as a baselayer, clicking on a shop marker links to Google Maps.
• The Ordnance Survey, Britain’s national mapping agency, withdrew support for OS Open Space on 31 August. OpenSpace was launched in 2008 using OpenLayers. OSM’s founder, Steve Coast, worked as a consultant to the OS on the initial project. Replacement services continue to be available via the new hub, but a number of existing applications and websites no longer work.

Open Data

• After a small pilot project in 2017, the Church of England announced their intention to map graves in all 19,000 churchyards in their care. The mapping, funded by Historic England, the National Lottery Heritage Fund and Caring for God’s Acre, uses LiDAR and is expected to take seven years. It is hoped that the resulting data will be open.

Mapping campaigns

• The Swiss OSM Project of the Month for September is the mapping of electrical vehicle charging stations > .

Mapping

• A long thread on the Swiss mailing list, split over several months, discussed how to map the border between Switzerland and Italy around Monte Generoso, where the precise line is uncertain. Earlier discussions occurred in July and August.
• John Stanworth wants to further improve his mapping of smoothness=* and mtb:scale=* and asked other cycling contributors for comments on his views.
• Hiddenhausen asked > , on the German forum, what the use of the tag landuse=street_green might mean. It appears to be an ad hoc attempt to refine the use of landuse=grass for grassy highway verges and medians.
• Voting is underway, until Saturday 25 September, for headlight=* to reflect the legal requirement on some roads to use your headlights.
• SK53 clarified with examples that, in his opinion, there is widespread misuse of the sac_scale=* tag for real alpine climbing routes, which the Swiss Alpine Club grades with a completely different scale.
• User Koreller asked for feedback on their contribution a guide to mapping North Korea available on the OSM wiki.

Community

• Amanda McCann shared with us what she did in OpenStreetMap during August 2021.
• Numerous OSM contributors have received ‘friend’ requests through the OSM website which appear to be phishing attacks. Not surprisingly this has received comments on the German forum >
  and OSM subreddit.

Imports

• Marius David (marius851000) intends > importing open data about restaurants in the Pays de la Loire (France), and he is seeking inputs on how to do it before starting.

OpenStreetMap Foundation

• Simon Poole justified his insistence that the OSMF register trademarks, whilst he served on the LWG, by referring to a recent trademark debacle involving PostgreSQL. A Spanish not-for-profit registered ‘PostgreSQL’ as a mark in Spain, and has recently applied for broader coverage in the European Union and USA. The latter application was recently abandoned, but the ‘PostgreSQL Community’ is still live.

• The UN Mappers team has announced the launch of an internship programme. Several open positions relate to OSM in mapping and feature extraction, social media and communication, geospatial analysis, and map visualisation and design. The internships are fully remote or in-person at the UN duty stations in Brindisi (Italy) and Valencia (Spain), and are open to all nationalities. These internships are an opportunity to work in an international environment, gaining experience and developing high skills in the humanitarian field. The deadline to apply is Saturday 9 October.

Humanitarian OSM

• The monthly HOT Tech Working Group meeting has been put on hold. The hot_tech team has convened a number of working groups specific to individual technologies or projects such as the OSM Galaxy Project. Anyone who wishes to participate in these is requested to fill out a form.
• HOT announced the appointment of Dr Ibrahima Cisse as Director of the Western and Northern Africa Open Mapping Hub.
• The Open Mapping Hub Eastern and Southern Africa (ESA), organised by HOT, announced a range of Open Mapping grants. Expressions of interest are invited immediately, with formal proposals expected during October.
• The HOT Quality Control and Assurance Working Group have developed and released the ‘Problem User Escalation Document’, which outlines the steps in escalating data quality problems encountered with users (mappers/validators).

Maps

• [1] The Institute for Software at the Technical University of East Switzerland (IFS OST) invites (Video ) us to check out their video regarding mapping technology for the Castle Dossier Map The video forms part of an entry for the Prix Carto of the Swiss Society of Cartographers.
• Jaisen Nedumpala reported on how he used OSM to help map a 3 km buffer zone during the recent Nipah virus outbreak in Kerala (India), with the personal support of Heinz_V from Germany and OSM contributors from Kerala.

switch2OSM

• Sustrans, the UK cycling infrastructure charity, asked for local input for improving a national cycle route in the city of Durham. Gregory Marler’s (user livingwithdragons) advice, given somewhat tongue-in-cheek, was to switch to OSM.

Programming

• The momepy Python library for analysing urban form is now at version 0.5.0. Of particular interest is the addition of the COINS algorithm for classifiying street hierarchies.

Did you know …

• … what the charging regime is for using the HOT Tasking Manager? Also known as the Tasking Manager Sustainability Model.
• … there is a page on the OSM Wiki for noting sites that use OSM but don’t provide correct attribution?
• … that OpenCage post geographical trivia via Twitter on the last Friday of each month (hashtag #fridaygeotrivia)?

Other “geo” things

• The Colorado Department of Transport falsely changed the status of an open road to closed, not only on their own site (albeit briefly), but directly on Google, Waze, TomTom and AppleMaps. A major highway Interstate-70 was actually closed due to mudslides, causing an increase in traffic on a minor road. The fictitious road closure was meant to discourage further traffic build-up.
• Using the example of the ‘Chinese Name of Lidl’ Yunus reflected on the challenge for western companies to select a Chinese name for their brand.

Mapping

• Requests have been made for comments on the following proposals:
  • natural=fumarole to map an opening in a planet’s crust, which emits steam and gases.
  • outlet=* to map culvert or pipeline outlets with more details.
  • historic=creamery for tagging an industrial building where butter, cheese or ice cream was made from milk.
• The proposal club=cadet, intended to be used to map the locations where various Youth Cadet groups meet, together with details of each group, has been approved with 15 votes for, 0 votes against and 1 abstention.
• [1] Anne-Karoline Distel aka b-unicycling, an Irish craftmapper, showed in a video how to capture details of vacant properties in OSM. When walking on site, she uses StreetComplete to leave notes in OSM, which she then edits in iD.
• Carl Myhill complained to Komoot that it was routing cyclists in Richmond Park (London) on paths where cycling is forbidden, and subject to a £60 fine. Komoot requires formal notification of such issues and this was provided by the Royal Parks. In the UK ways mapped as track, service, or path cannot be assumed to allow any access mode other than private without other explicit tagging. Komoot, however, does not follow these defaults.
• Over a period of five days, participants of University Battle Mapping 2021 mapped over 93,000 buildings in Indonesia.
• Barry McGuire suggested a large scale revision of how the highway=trunk and highway=primary tags are used in the UK, including an associated proposal on the wiki. Unfortunately, instead of assessing feedback on the mailing list, and the wiki, he made a number of edits following his new scheme. Judging by changeset comments these were not popular and have now been reverted.
• On the forum NicoHood asked about using the class:bicycle key for the left and right sides of highways. Most responses suggest using alternative, more objective, tags.
• LysSioS reported >
  that they have finished mapping addresses in the commune of Alès. Mapping rural addresses proved to be much more time consuming than urban ones.
• mariotomo described in detail how to capture missing road sections using Strava’s low-res heatmap. However, he notes slightly ironically: ‘The mapping practice described here is completely manual, and its speed is obviously inversely proportional to the desired precision’.
• mdroad has come up with a decision matrix for classifying roads. For beginners, the wiki pages Highways and Highway_tagging_samples/out_of_town with their pictures are also very helpful.
• Reddit user sporesofdoubt has now completed micro-mapping the 183 city parks in Phoenix, Arizona over the summer (we reported them reaching the 100 park milestone earlier).

Community

• The recordings of HOT’s webinar Local OSM Community Building: Tips, Tricks and Challenges are now available.
• cmoffroad outlined their experience of being a new OSM mapper in Thailand. AlaskaDave, nitinatsangsit and Bernhard Hiller tried to ease the frustrations of the beginner with their local knowledge.
• Free Local Mappers from Guinea, in its drive to promote GIS and openness of spatial data, recently conducted ​ > a series of GIS and remote sensing training sessions for employees of an international firm based in Conakry.
• The State of the Map conference has begun uploading videos from July to YouTube and media.ccc.de. The talks that had audio translations into other languages will be uploaded when they have been finalised by the volunteer translators.
• Trufi Association has hired a staff of five professionals, graduating from the public transport mapping organisation’s two-year run as an all-volunteer NGO.
• User Tirkon complained > , on the German forum, about OSM tiles not refreshing. The ensuing discussion covers a lot of ground regarding how map updates get to users’ screens.

OpenStreetMap Foundation

• The Engineering Working Group of OSMF is looking for people with knowledge of the technologies used in OSM’s key systems: Rails port, Ruby on Rails in general, and the cgimap implementation of the OSM API. Knowledge of user interface design would be also welcome.

Humanitarian OSM

• OSGeo and HOT signed a memorandum of understanding with the goal of fostering the use of open-source geospatial software, to enable participatory community-driven development.

Maps

• The French air quality observatory ATMO’s Atmo Data released a map showing measured data nationwide which uses OpenStreetMap as a baselayer.
• Tracestrack is inviting people to trial its tile service. Users can do this for free until March 2022. The map is based on the OSM-Carto style, with some unique characteristics: support for several extra tags, such as highway=busway,embankment=yes, and landuse=aquaculture, semi-transparent highway areas, separated language labels and 3D buildings. Unfortunately the appropriate attribution is hidden.

switch2OSM

• SomeoneElse has provided additional documentation for building a tile server on Ubuntu 21.04. This is not a long-term support release so Ubuntu 20.04 LTS is still the preferred platform for production. He also notes a couple of issues which may occur whilst following these instructions.

Open Data

• The website datos.gob.es, a platform where the Spanish government promotes open data, has included the Organic Maps > app in its catalogue, highlighting that it is an open source app and is based on OpenStreetMap data.

Licences

• Owen Boswarva reported that open data on power infrastructure in the UK are scheduled for release in October. Jo Walsh (ultrazool) asked about which licence would be used, resulting in a short discussion about the suitability of various open licences for non-government open data.

Software

• Just in time for the beginning of autumn in the northern hemisphere, the OpenSnowMap for mobile devices has been comprehensively revised.

Programming

• The Overpass API Python Wrapper project is looking for a new maintainer. Martijn van Exel started this project 7 years ago, but he has indicated that he does not have the time to maintain it any more. The project has been starred on GitHub more than 260 times.

Did you know …

• … the English county of Devon has adopted special notation on road signs? The goal is to indicate that specific roads or routes are not suitable for various types of vehicles, including those towing caravans.
• … the wiki page on homonymous keys? The page is largely maintained by Minh Nyugen, and it identifies keys that mean different things according to how they are used.
• … the complete tools collection for OpenStreetMap built by Pascal Neis?

Other “geo” things

• GeoHipster is planning to publish a calendar again for 2022 and is asking for submissions of your maps.
• Ars Technica reported on new technical analyses of the Vinland Map (of the North American Atlantic coast), long suspected of being a fake. The new data remove any residue of doubt that it is, indeed, a fake. X-ray fluorescence spectroscopy was used to analyse the elemental composition of the entire map. This confirmed the presence of titanium dioxide, a pigment which only started being used in the 1920s, throughout the lines and text of the map. A true medieval gall ink would have had considerable quantities of iron instead.
• Jdanni’s diary is less about whether smartphone track logs pollute the OSM map, but much more about GNSS position accuracy in various scenarios reported in the links.
• The Thermal Energy Company of Gdynia has published >
  a map showing thermal energy losses across the city and adjacent communities.
• Yarik32 has written > a tutorial on how to create OSM-based memes using Overpass Turbo and QGIS.

• Mirek se pouští do mapování ZBOxů od Zásilkovny.
• Jak je to s aktualizací polygonů administrativních celků jako jsou obce, kraje nebo okresy, dělá se automaticky nebo vůbec?

OSM SK

• Jak ideálně použít živé sledování polohy přes Locus, aby to nezatěžovalo server aneb 4 dny a 5500km s elektroautem.
• Co a jak je potřeba udělat, pokud chce tvůrce na nové cyklotrase použít mapy freemap.sk?

Mapovací kampaně

• Tým OrganicMaps žádá své uživatele, aby pomohli s pomocí validátorů opravit chyby v mapování metra. Brandon navrhuje, že by bylo dobré zkusit spolupracovat s nedávno vydanou novou aplikací pro Jungle Bus.

Mapování

• MapSpot vytvořil několik map ukazující postup projektu modernizace řek, který nahrazujewaterway=riverbank za natural=water a water=river.

Komunita

• Belgická komunita OpenStreetMap zvolila Mappera měsíce pro září – je jím Donat Robaux (gendy54) z Francie.

Importy

• foxandpotatoes vysvětluje, jak přesně používat oficiální zdroje se vztahem k belgickému katastru pro dokončení nebo opravu dat OpenStreetMap co se týká administrativních hranic.

Nadace OpenStreetMap

• Roland Olbricht vysvětluje cíle a úkoly nové Engineering Working Group (EWG), které se stal předsedou.

Novinky lokálních zastoupení

• Šťastné narozeniny OSM-FR! Francouzské lokální zastoupení bude slavit své 10. narozeniny v pondělí 10. října na několika místech Francie.
• Universita v americké Arizoně bude pořádat 1. – 3. dubna 2022 příští konferenci State of the Map US. Sejdeme se v Tucsonu!
• Zářijové číslo měsíčního zpravodaje amerického lokálního zastoupení je online.

Události

• Topi Tjukanov oznámil kategorie pro 30 denní mapovou výzvu, která se bude konat během listopadu 2021. Jedna z výzev jsou přímo prvky OpenStreetMap.
• Žádost o nominace míst pro pořádání mezinárodní konference State of the Map 2022 (informovali jsme dříve) zůstala bez reakce. Andrew Hain se ptá, zda je potřeba lépe promyslet, jak se potkáme? Nebo je problém, že psané i nepsané podmínky na místo konání jsou příliš svazující?

Mapy

• Chetan Gowda si žádá zpětnou vazbu pro své tištěné mapy v indickém jazyce Kannada.
• Marcos Dione bloguje o tom, jak vyřešil vykreslování osamocených bodů zájmu v nízkých přiblíženích v porovnání s stejným typem bodů v hustých oblastech.

Software

• Bryce Cogswell oznámil vydání aplikace Go Map!! v3.0 pro iOS. Ve svém deníku vzpomíná Bryce také na to, jak vlastně Go Map!! vzniklo.
• Byla vydána verze 4.0 routovacího systému GraphHopper. “Prostorová pravidla” byla nahrazena a rozšířena s pomocí uživatelských oblastí. Ty lze použít k vytvoření oblastí, které upravují pravidla silniční sítě. Typické použití je úprava pravidel dle země, například pro rychlostní limity.
• NLnet je nadace, která “financuje ty, kteří mají nápad, jak opravit internet”. Výzva k předkládání otevřených návrhů pro financování projektů, které pomohou tvořit “otevřený, důvěryhodný a spolehlivý internet pro všechny”, může pokrývat i projekty s tématem OpenStreetMap, takže je možná dobrý nápad se přihlásit.

Věděli jste …

• … že Richard Fairhurst sepsal ilustrovaného průvodce Poskytování dat do OpenStreetMap, který je určen lokálním úřadům a jiným vlastníkům dat?
• … že Anne-Karoline Distel (uživatel OSM b-unicycling) spravuje kanál YouTube se spoustou nápadů a rad pro milovníky historie?
• … že na wiki najdete seznam externích zdrojů dat, které byla importovány do OSM?
• … že barevné schéma vrstvy OSM Mapnik, kterou nahradilo upravené schéma CartoCSS bylo v roce 2013 cílem výzkumu vědců z univerzity v Hamburku? Richard Fairhurst, který originální schéma vytvořil, spekuluje, že úsilí věnované výzkumu bylo výrazně větší, než to, které stálo za výběrem barev.

Ostatní geo záležitosti

• Poslední a nedávné vlákno OpenCage na téma zvláštností v geografii #geoweirdness je zaměřené na Španělsko. Vlákno začíná obrázkem multipolygonu natural=lava, který zadal do OSM přispěvatel sergionaranja při příležitosti aktuální erupce sopky Cumbre Vieja na ostrově La Palma.
• Užíváte si letecké snímkování s dronem? Pozor, abyste se nedostali příliš blízko divokým zvířatům. Jeden krokodýl v Austrálii tahle ulovil nízko letícího drona, který zachytil své poslední okamžiky na video.

OSM SK

• bez nového vlákna

Mapování

• Daniel Capilla píše > ve svém deníku, že realita dnešní Malagy již nemá nic společného s tradičním klišé Malagy, jako města tisíce barů a jediného knihkupectví. Podkladem budiž zmapovaná knihkupectví a knihovny tohoto města v OSM.
• Probíhá hlasování o návrhu boundary=border_zone určeného pro tagování hraničních oblastí se speciálním omezením pohybu osob (do pátku 22. října).

Komunita

• Tým dobrovolnických mapperů OSN se rozhodl zorganizovat své první online školení v Portugalsku. Na akci se také podílela výzkumná skupina Munzuá z UNILAB > . Během šesti lekcí po třech hodinách se cílilo jak na školení nových mapperů, tak i na vhled do celého ekosystému OSM. Celkovým zaměřením programu je podpora rozvoje komunit OSM v portugalsky mluvících zemích Afriky. Kromě jiného byla tak do portugalštiny přeložena i wiki stránka Highway tag Africa.
• Organizace NOAH (Nationwide Operational Assessment of Hazards) při Filipínské univerzitě formálně spustila svou upravenou webovou stránku, která používá data OpenStreetMap pro identifikaci rizik pro celou zemi.
• Po jediném týdnu v kůži mappera ve světě OSM se Sebastian Helm podělil ve svém deníku o první dojmy a zkušenosti z mapování a poukázal na některé aspekty, které pro něj jako nováčka byly složité.
• Simon Poole sdílí informaci, že 5. října poslal v pořadí již 10000. uvítací zprávu novému mapperovi. První byla poslána v listopadu 2015.

Nadace OpenStreetMap

• Dorothea Kazazi zveřejnila tři zprávy zdůrazňující nedávné aktuality se vztahem k Nadaci OSM, včetně zpráv o lokálních zastoupeních a statistiky členství.
• Amanda McCann na osmf-talk mail listu navrhuje, že označení State of the Map by nemělo být používáno pro akce v místech, kde je zakázána nebo postihována homosexualita.
• Byl zveřejněn zápis z jednání rady Nadace OSM z pátku 24. září.

Novinky lokálních zastoupení

• Christian Quest píše > při příležitosti jejích 10. narozenin o vzniku OpenStreetMap France.

Události

• Pista ng Mapa (Festival of Maps) je otevřená konference pořádaná na Filipínách. Registrace je otevřená do neděle 31. října.

Vzdělávání

• Ve svém průvodci Amanda McCann demonstruje využití různých pozicí GPS pro mapování, vytváření zakřivených a neobvykle tvarovaných budov a teras.
• Amelia Hunt a Doug Specht z londýnské University ve Westminsteru publikovali ve sborníku Journal of International Humanitarian Action článek “Dobrovolnické mapování v krizových zónách: spolupráce, organizace a dopad”. Ten ukazuje případové studie zaměřené na dobrovolnické komunity jako jsou Standby Task Force (SBTF), které se aktivují v případě potřeby na základě žádosti mezinárodních organizací nebo lokálních aktérů. Tyto komunity analyzují v reálném čase během konfliktů nebo neštěstí informace ze sociálních médií a vytvářejí mapy bodů zájmu.

Humanitární OSM

• HOT Open Mapping Hub – Asia Pacific oznámil svůj program Booster Grant – investice do komunity a ekosystému OpenStreetMap v oblastech Bangladéše, Nepálu a Filipín.
• Valná hromada HOT konaná 7. října zvolila pět členů správní rady. Chad Blevins nahradil Matta Gibba jako nově zvolený předseda. Byly také schváleny čtyři dodatky stanov organizace.
• Pokračující prezident rady HOT Miriam Mapanauta sdílela svoji zprávu pro období 2019–2021.

Mapy

• Open Etymology Map ukazuje etymologii jmen na základě OSM a Wikidat.

Licence

• LySioS přemýšlí, zda by deklarace práv a majitele OSM nebyla lépe prezentována pomocí obrázku, respektive loga než pomocí textu. Několik lidí v diskuzi odkázalo na předchozí komunikace na toto téma.

Software

• Geofabrik tweetuje, že jejich nástroj pro kontrolu kvality OSM Inspector je nyní aktualizován dvakrát denně.
• Pieter Vander Vennet vydal novou verzi MapComplete. Jak popisuje ve svém deníku, obsahuje hromadu nových témat (například nabíjecí stanice, hospody a kavárny nebo restaurace), dále zlepšení výkonu a také nové vlastnosti. Příspěvek v deníku končí žádostí o pomoc s rozvojem MapComplete, například s překladem.
• Boa Percivala zajímá názor komunity na budoucnost nástroje Tasking Manager. HOT_tech hledají také zástupce komunity jako správce Tasking Manageru, takže pokud by vás to bavilo, rozhodně se ozvěte.
• Sarah Hoffmann zkoumá některé problémy, zjištěné při pokusu o práci se jmény v různých jazycích. Další verze nástroje Nominatim bude podporovat jazykově specifickou práci se jmény a to i co se týká jmen bez suffixu klíče pro určení jazyka.
• Validátor pro metra (o kterém jsme informovali dříve), původně vytvořený Ilyou Zverevem, je nyní hostován na Mail.ru. Další detaily o tomto nástroji jsou dostupné na wiki a zdrojový kód je na GitHubu.

Věděli jste …

• … že klíč floor:material je určen pro tagování stropů (technicky nejnižší část budovy s nenulovou hodnotou minlevel). Taginfo ukazuje, že je spíše v místech jako je Nepál používáno pro pro tagování podlah. Jedná se o jeden z tagů s matoucím názvem, které jsou zdokumentovány na wiki.
• … že tvary nekruhových točen lze popsat pomocí klíče turning_circle? Nedávná dokumentace jeho použití pochází o uživatele Jdcarls2.
• … o JOSM vykreslovacím stylu Coloured Streets pro lepší mapování adres? nickjohnston vysvětluje, jak tento styl pomáhá mapování adres zlepšit.
• … o projektu vroom na GitHubu od Juliena Coupeye? Jedná se o open source aplikaci pro řešení problému obchodního cestujícího. Vroom je dostupný pod licencí BSD a spoléhá se na data OpenStreetMap, speciálně lze využít OSRM, Openrouteservice nebo Valhalla.
• … o Krizové mapě OSM?

Ostatní geo záležitosti

• Mezinárodní tým vědců přinesl studii, podle které byly Azorské ostrovy zřejmě obydleny > o 700 let dříve, než se doposud myslelo. Předpokládalo se, že ostrovy byly objeveny portugalskými námořníky během 15. století, speciálně ostrov Santa Maria v roce 1427 a ostrovy Corvo a Flores v roce 1452.
• Válka map: Čína diktuje > (placeno) světu své hranice s pomocí map.
• The Billion Dollar Code je seriál německého Netflixu, který se mimo jiné zabývá právní bitvou ohledně tvrzení, že Google Earth je plagiát systému Terravision vytvořeného firmou ART+COM.
