Breaking news

• Paul Norman announced the release of version 5.7.0 of the OpenStreetMap Carto Stylesheet, the default map stylesheet for the OSM website, on the mailing list and in his blog. All changes can be found there.The most obvious change, as the OSM Ops team tweeted, is the representation of unpaved roads. Unpaved roads will be rendered with a subtle stipple effect to show them as being not paved. The OSM Ops Team says: ‘Unpaved roads with a suitable tag will be styled differently. Change background: https://github.com/gravitystorm/openstreetmap-carto/pull/3399‘.The Ops team goes on to say ‘this unfortunately leaves a dilemma, many regions in OpenStreetMap unpaved is the presumed default in the absence of a surface= tag. But! We can fix this, let us map if roads are surface=paved or surface=unpaved (or more specific types)’.The OSM Ops Team then turned to three organisations with a friendly appeal for help: ‘Germany already has 46% of roads surfaces mapped. Zimbabwe it is only 14%. So let us get mapping road surfaces! How about it? @hotosm @osmafrica @youthmappers’.

  Ways with no surface tag can easily be found using overpass turbo.

Mapping

• -karlos- blogged ► about ‘area’ as a new object type in the OSM data model, why in his opinion it is a good improvement, and where he expects difficulties to arise.
• Bob Cameron (bob3bob3) described how he takes photos and audio commentaries on the road and processes them automatically to use them at home for improving OSM.

• Kai Johnson explained how he distinguishes between highway=service and highway=track.
• Lars Schwarz is experimenting ► with using the 3D Model generated by Polycam to collect infrastructure data for OSM.
• Quite Frankly is embarking on a project to ‘document and update cycle lanes on every street in Melbourne and eventually Victoria in as much detail as possible’ using tagging schemes that he says were developed specifically for the detailed documentation of cycling infrastructure ►. Other tools being used: StreetComplete, iD, JOSM, Vespucci and Hauke Stieler’s Simple Task Manager.
• steveman1123 blogged about his armchair mapping activities and what keeps him motivated while doing so.

The team proposed a novel few-shot transfer learning method (FSTL) to improve humanitarian organisations’ mapping workflows in the Global South. Further details on the approach, and its current limitations, is available on the HeiGIT site.

Licences

• Pieter Vander Vennet investigated, using Overpass, what licences MapComplete users are applying to their uploaded pictures. The vast majority are uploaded with the default licence, being CC0/public domain. Power users, though, often change the licence to CC-BY or CC-BY-SA. As a by-product of his investigation, a ranking of MapComplete’s most active users has been compiled, led by ‘legendary mapper’ Awo.

Software

• Anne-Karoline Distel spotted that Field Papers was not working (see also a Reddit thread). Ciarán (DeBigC) reported it on GitHub and, fortunately, Alan Maconchie restarted the server. However, as with other Stamen services, they are looking for others to take on support.

OSM in the media

• Carey Davies, writing in The Great Outdoors magazine, provided in-depth analysis of recent mountain rescue incidents in the English Lake District, which were occasioned by the use of outdoor hiking apps based on OpenStreetMap data. Earlier, The Guardian and online magazine Grough had also covered this topic. It is these reports that led to SK53’s path analysis, which we reported earlier.
• Alex Roddie, quoted in The Great Outdoors article above, published his own detailed analysis of the use of OpenStreetMap by a range of outdoor hiking applications. He received a lot of feedback from experienced UK-based mountain guides on both Twitter and Mastodon.
• Netzpolitik recommended ► installing StreetComplete and other FOSS tools to rid yourself of GAFAM.

Other “geo” things

• Google Maps has introduced a visual positioning system ‘to provide location and navigation services for users of its AR “Live View” feature’.
• Giorgia Tolfo blogged on how the Living with Machines project is digitising 19th century Ordnance Survey maps from the British Library.

Mapping

• Requests have been made for comments on the following proposals:
  • amenity=showground to describe open areas (typically grassy or gravel) which are maintained to be used for outdoor events.
  • landcover=* version 2 to formalise the usage of the key landcover=* and deprecate the tags landuse=grass and landuse=flowerbed.
• Voting is currently open until Friday 24 February for:
  • emergency=air_rescue_service, for tagging buildings and base areas of those groups that use aircraft for either aerial search and rescue or medical evacuation purposes.
  • emergency=water_rescue, for mapping the buildings and base areas, both on and off water, of those groups that are dedicated to the rescue of vessels and/or sailors in distress.
  • emergency=fire_water_inlet, for mapping an inlet to a building’s firefighting system.

Community

• Martijn van Exel has sent out the final OSM Tips email (we reported earlier). After a three month trial Martijn has decided to invest more time on MapRoulette in the future.
• MoiraPrime reflected on the current state of the map in Mississippi and concluded that the issues identified can be fixed with the help of the community. She listed a number of ways to get in touch with the Southern US community.

OpenStreetMap Foundation

• The OSMF Engineering Working Group has decided that the call for proposals to add the ability to mute users on the openstreetmap.org website (we reported earlier) will close on Monday 13 March.

Events

• About a year ago, Martin Raifer started working as the maintainer of the iD editor for the OSMF (we reported earlier). He has blogged a short recap and outlook of what’s lying ahead according to him. He wants to host regular online community sessions to chat about the iD editor. The first of these chats will take place on 20 February at 4 pm UTC with the topic ‘the state of the tagging presets – recent changes and development tips’.
• Ilya Zverev announced that SOTM Baltics 2023 will be held in Riga on 18 and 19 May, where OSM-Baltic will join with the BalticGIT organisation team, the same arrangement as three years ago. This will give everyone interested in open data and open tools an opportunity to gather together to present their work, meet other mappers and developers, and spend two days in a beautiful city on a super wide river.

Education

• While training in French for beginners has already started (‘OpenStreetMap and Humanitarian Mapping’, which we reported in #651 and #655), the UN Mappers announced that this free training will also be provided Portuguese starting Wednesday 22 March. All interested Portuguese speakers are invited to register.
• Christian Hollinger encouraged beginners to get a handle on QGIS, for everything from basic data to elevation data and inserting photos. There is a lot for newcomers.

Humanitarian OSM

• Heather Leson, Dinar Adiatma, and Can Unen shared links to help new and experienced mappers get started with HOT mapping in Turkey.
• pedrito1414 addressed the question ‘is what I am doing really helping anybody in a disaster situation?’ with some statistics. The answer is yes.

Maps

• Alan McConchie interviewed Tanya Ruka, a Māori indigenous multimedia artist and designer who is the new Executive Director of Native Land Digital, an organisation with the mission ‘to map Indigenous lands in a way that changes, challenges, and improves the way people see history and the present day’.

Software

• MapTiler now has an Ocean map style available on MapTiler Cloud. The 15 arc-second elevation dataset provided by GEBCO was processed into an optimised Ocean tile set.

Other “geo” things

• In the latest edition of OpenCage’s #geoweirdness, even a Brazil specialist is sure to find some more interesting facts.
• The MapScaping Podcast recently discussed how AI can be used to generate artificial satellite imagery using generative adversarial networks (GANs). They tweeted four lookalikes – are you able to tell which is fake?
• Five days after the Turkey–Syria earthquakes, researchers have produced a map of the ground movement along the East Anatolian Fault. They did this by using before and after data from the EU’s Copernicus Sentinel-1A satellite, which carries a synthetic-aperture radar instrument that is able to routinely sense changes in elevation of the Earth’s surface. Neither of the two most serious earthquakes here were limited to a single epicentre; the first was a 300 km long rupture in one fault and the second a 140 km long one in another.
• Matthew Beedham drew an analogy between Overture Maps Foundation’s aim to develop standards for interoperability and shipping containers.

Mapping

• Anne-Karoline Distel has spent a very interesting, challenging and turbulent four weeks mapping the National Monuments of Ireland.
• Bob Cameron has talked himself hoarse, having spent the past two months ‘intensely’ making observations around the lesser populated areas of southwest Western Australia, almost solely from his vehicle’s driver’s seat.
• Valerie Norton wondered how to handle a path dispute in the woods of California. The path was surveyed (as informal) but then removed as a ‘non-existing trail’ (presumably meaning non-existing on the USGS maps that were used as one of that changeset’s sources). Looking at the pictures it doesn’t look that informal – there are even signs!
• Voting on the proposal to replace *:signed with is_signed:* is open until Wednesday 1 March.

Community

• Geomob Podcast’s host Ed Freyfogle chatted with OSMF board member, and early mapper, Mikel Maron in episode 169.

Local chapter news

• Minh Nguyen reflected on four years of serving on the OpenStreetMap US board.
• OSMCha has been welcomed as an OSM US Charter Project. The Charter Project designation provides OSMCha with a sustainable home that allows the project to be governed by input and leadership from across the community, including corporate users and donors.

Events

• The FOSSGIS conference app has been updated for the 2023 conference schedule. If you don’t already have it installed, you can install it via Google Play.

Humanitarian OSM

• The Smart Mobility team of HeiGIT have set up an instance of the disaster openrouteservice in response to the earthquakes in Turkey and Syria. The disaster openrouteservice provides near real time updates from OSM. Currently, the underlying OSM data is being updated every 10 minutes. The availability of this type of accessibility analyses can be crucial for disaster management, especially taking into account roads that have recently been added or marked as damaged by participants of a mapping activity.
• Said Turksever published an overpass turbo map showing mobile pharmacies temporarily located in the areas affected by the Turkey and Syria earthquakes.
• MapRoulette has a mapping challenge to add pharmacies in the disaster areas of Turkey and Syria.
• Pete Masters has found a variety of maps that make use of the updated OpenStreetMap data mapped after the earthquakes in Turkey and Syria.
• Unen gave an update on OSM helping the Turkey and Syria earthquakes response. He summarised current activities and proposed priorities for future activities.

Maps

• [1] Using the Global Human Settlement Layer, Tom Forth has created a website which will estimate the population inside a circle of your choosing on a map. The population figure calculated by the software agrees quite closely with the official data published on the web.

switch2OSM

• The car sharing provider Stadtmobil has switched ► from Google Maps to OpenStreetMap. The switch has been made because ‘unlike Google Maps, OpenStreetMap is usually more up-to-date and detailed because it is a free wiki world map that is constantly updated by its users’.

Software

• Pieter Vander Vennet noted that Bing Map builder edits have stopped appearing in OSM. He is not sure if this was a result of his previous post on the subject (we reported earlier), something that they were already planning to do, or a little of both.
• ‘Quirqui Rutas’ is a new public transport app that was developed in two weeks and launched during the Carnival of Oruro (Bolivia). The app uses open source code from the Trufi Association and route data that was surveyed by locals Henry Flores and Jhonny Lazarte and entered into OSM by students from the Salesian College in Duitama, Columbia.

Programming

• Stadia Maps have created a developer’s tutorial on how to build an interactive map with React Leaflet, which can displays hundreds of markers using only a few lines of code.

Releases

• Martijn van Exel announced the availability of a beta version of RapiD 2.0. The thing he thinks you will appreciate most is how snappy RapiD feels, as the majority of the work on RapiD 2.0 has gone into performance improvements. The Maps@Meta team provided more details in a OpenStreetMap US blog post.

Did you know …

• … TracesMap? Select the appropriate layer and you can see the traffic situation, cycle paths, underground, bus or train lines, or GPS tracks displayed.

OSM in the media

• Because Mapbox has become expensive, the Washington Post has been moving to alternative mapping tools. Kevin Schaul outlined how the Post is replacing Mapbox with open source solutions.

Other “geo” things

• How #geoweird is Italy? OpenCage tooted some of the geographic peculiarities of Italy, including the disputed territory around Mont Blanc.
• Meta has been busy improving their map products. Their Daylight team has developed an ‘earth table’, a data schema that classifies OpenStreetMap-style tags into a three-level ontology: theme, class, and subclass, which helps them with their cartography.
• In a Pan-European effort ► a Ukrainian driver reversed a Polish semi-trailer (articulated lorry for British readers), carrying German goods, into a French retaining wall in Rue de Charrière. The accident was blamed on satnav but appears to be more related to the fact the street is a dead-end and there is nowhere for a truck to turn around.

Breaking news

• OSMTech announced, on March 2, that the long-planned import of the content from the old forum into the new OSM Community forum will take place in the coming week. There may be some associated downtime of the Community site.

About us

• [1] Pieter Vander Vennet was interested to know how much of a transition has been made from Twitter to Mastodon by the OpenStreetMap community. His approach was to count links from weeklyOSM to the two sites, allowing a comparison over quite a long time, back to 2020. It appears that Mastodon has become more used over the past two months. November was an anomaly because of both the #30dayMapChallenge and the listing of OSM-relevant Mastodon accounts.

Mapping

• Martijn van Exel has written two blog articles on how to capture and upload 360° imagery with Mapillary. The first covers capturing images while walking and the second biking.
• Pete Masters passed on the thank you from Dr Bilgehan Çevik, an orthopaedic surgeon working in Ankara, Turkey, for the help they received through Organic Maps from OSM.
• Alex Seidel (Supaplex030) explained how streetside parking tags have been overhauled, mainly to make them easier to understand. He provides overpass turbo queries to detect older usage, a tool to assist in updating the tagging, and tips for use in JOSM, including a parking-specific style.
• Requests have been made for comments on the following proposals:
  • highway=trailhead for mapping a designated or customary place where a trip on a trail begins or ends.
  • Public transport auditory information, a tagging scheme for describing what kind of auditory information is available on public transport stations and platforms.
• Voting on emergency=fire_service_inlet, for mapping an inlet to a building’s firefighting system, has finished and the proposal was successful with 26 votes for, 1 vote against and 0 abstentions.

Community

• Grant Slater, from OSM Ops, asked users of the old forum to check their own posts in a test import of the forum to Discourse. The import is a snapshot from 2 February 2023.
• Alan McConchie has extended the entry deadline for the ‘OSM Oscars‘ until Tuesday 7 March. So if you still want to submit nominations, please hurry.
• Pete Masters and Rubén Martín have published HOT Community Weeknotes: 8 / 2023, discussing recent activities and what’s coming up for the humanitarian open mapping community.
• Said Turksever and the Turkish OSM community have been chosen as Mappers of the Month by UN Mappers for the invaluable coordination of the mapping work done in the aftermath of the earthquake that hit Syria and Turkey on 6 February.
• OpenStreetMap US provided an update on progress with the Trails Stewardship Initiative. Using selected areas in the Pacific Northwest, familiar to a range of stakeholders, tagging and mapping approaches have been trialled with both land managers and app developers.

OpenStreetMap Foundation

• The OSMF is looking for volunteers with skills in graphic design to help add visual storytelling to their blog, social media, and other channels in order to support OSM events, fundraising, developer projects, and more.

Local chapter news

• Congratulations to Diane Fritz, Matthew Whilden, and Priyanka Miller, who have been elected to the OpenStreetMap US Board.

Events

• Unique Mappers Network Nigeria are holding ‘Let’s DigitAll for Women’ starting on Wednesday 8 March, International Womens’ Day (IWD2023). The event incorporates a panel session (8 March), three training sessions (8 to 10 March), and a two week long mapathon and school outreach finishing on 22 March.
• A Trufi Association webinar, to be held on Tuesday 7 March, ‘Mobility as a Service (MaaS) in the Global South and Sustainable Mobility’ will include a discussion of how OSM democratises mobility data.

OSM research

• Moritz Schott, Sven Lautenbach, Leonie Großchen, and Alexander Zipf presented a new tool in their paper ‘OpenStreetMap Element Vectorisation: A Tool for High Resolution Data Insights and its Usability in the Land-use and Land-cover Domain’. The OpenStreetMap Element Vectorisation addresses the much-discussed issue of fitness for purpose. It currently provides access to 32 attributes at the level of single OSM objects.

Maps

• TrekkingTrails reviewed
  an extensive range of eleven OSM-based maps designed for hikers.
• Where would your balloon fly if you could launch it from a place of your choice? Using OSM and meteorological data from the past 91 days this map will display its trip around the world.
• Tracestrack has open sourced their bus route Carto-CSS map style. This style focuses on bus/tram routes and stops. With colour-coded routes, the style tries to explore a better way to present many bus routes.

Software

• Researchers from ETH Zurich presented Eduard, machine learning-based software for generating shaded relief maps, inspired by the work of Swiss cartographer Eduard Imhof.

Programming

• OrganicMaps are a participant in the 2023 Google Summer of Code, and have listed ideas for projects on GitHub.
• Martijn van Exel wrote a longish post about how he used osm2pgsql to set up and maintain the database that powers Resto-Bot, the bot that toots out the OSM database every day for restaurant features that have not been updated in more than five years.
• Jochen Topf described how he has extended the tile-expiry feature of osm2pgsql. Tiles containing changed data have always been written to a list in a file, allowing selective rendering of the affected tiles. In order to work with generalised features the approach needed to be enhanced: firstly, by storing the list in a database table, and secondly, by keeping multiple lists allowing features or layers to be expired independently.

Did you know …

• … there is a MapRoulette plugin for JOSM?
• … the Gefahrenstellen.de (danger point) project? Arno Wolter, one of the three founders and CEO of the Initiative for Safer Roads, talked about their new project Gefahrenstellen.de, which seeks to help parents and schoolchildren select the path to school with the least traffic and risk. The project uses HeiGIT’s openrouteservice as a routing service, which in turn uses OSM data.
• … the TreeTalk map can help you answer the question ‘What kind of tree is that?’ The map provides tree information for 26 boroughs in London.

Other “geo” things

• The rivers of Europe! Coloured according to their basins and scaled by the volumes of water flowing through them; data from hydrosheds.org.
• Christopher Beddow discussed the challenge of maps covering fractal levels of detail, and attempting to symmetrically represent the world, or at least how we perceive it.
• The Trufi Association’s volunteer of the month is Eva Asturizaga. If you would like to volunteer for the Trufi Association you can find out how on their website.

The age of POIs on OpenStreetMap the USA [¹] | © Martijn van Exel | map data © OpenStreetMap contributors

Mapping

• [1] Martijn van Exel tooted some choropleth maps of the age of POIs on OpenStreetMap in the US. These used the same database, populated with osm2pgsql, as RestoBot (we reported earlier).
• Martijn van Exel found that his 360° imagery became sharper, and more readable for OSM tagging purposes, if he mounted the camera sideways.
• iboates noted everything you need to know about mapping electric vehicle charging stations. He put special focus on capacity tags and explained when it is unnecessary to specify the number of cars.
• ltog noticed that, in certain circumstances, the iD editor suggests extracting a POI node from a building outline, which, if no further action is taken by the user, results in a duplicate node in exactly the same location. In his view this suggestion may be inappropriate in many use cases.
• The MapWithAI Twitter account suggested deleting buildings which are already mapped to allow building outlines extracted from satellite imagery to appear in their place within the editor. As a reminder, good practice is instead to replace existing geometry, so as not to lose building history, as Tom Hughes explains in response to this tweet.
• Peter Elderson blogged about mapping embankments and all their details.
• SK53 posted two new instalments of his diary post series about unusual things seen whilst mapping solar power in Wales. The first discussed stone circles built in modern times and how to tag them. He believes this is one example of a more general issue when objects fall outside the original scope of the main tag usage.
• In his second post, SK53 described how he used open data derived from old maps from around 1900 to locate disused windmills on the island of Anglesey. He pointed out that the technique is applicable to a wide range of historical and archaeological features.

  When Richlv revealed on Mastodon that his mother is an expert on Latvia’s old windmills, SK53 pointed out the Windmill World site based on OpenStreetMap data.

• Matt Whilden has used GNIS data and MapRoulette to improve the mapping of mobile home parks in Arizona.
• Yivan000 has compiled a summary of the numerous standards and tagging practices being used to map subdivisions in the Philippines. He explained his tagging standard, which aims to be more fitting for subdivisions.
• The proposal ► for standardising the mapping of Parque Escolar in Portugal has entered the voting phase. For more information, consult the project’s wiki page or the group’s official channel on Telegram.
• Voting on emergency=water_rescue, for mapping water rescue bases, has finished. The proposal was successful with 20 votes for, 3 votes against and 0 abstentions.
• The proposal to replace *:signed with is_signed:* was rejected with 6 votes for, 10 votes against and 0 abstentions.

Mapping campaigns

• Since July 2022 Sahil Dhiman (sahilister) has done an exemplary job of mapping in OSM all schools in Chandigarh (we reported earlier). As he shared in his blog post, he is now turning his attention to the schools and colleges in the neighbouring town of Panchkula.

Community

• OSM old-timer Gregory Marler, aka LivingWithDragons, was interviewed as OSM Belgium’s Mapper of the Month.
• Ohene123 has written a brief outline of a project about women being under-represented in the OSM community. She is asking for people to fill out a survey on this matter.

Imports

• Pieter Vander Vennet has analysed the outcomes of the Visit Flanders mapping campaign after one year (we reported earlier). He summarised that using map notes for a guided import works well for small imports (<100 nodes). For bigger datasets (especially if >500 points), he recommends MapRoulette as an alternative.

Local chapter news

• The OSM Belgium chapter has sent out their latest quarterly newsletter. It includes a call to help with mapping their top tasks.
• USGS, the US national mapping service, published a guest blog about the OSM US Trails Stewardship initiative (we reported on the current status recently).

Events

• Geoffrey Kateregga provided a detailed breakdown of how State of the Map Tanzania 2023 went about choosing technology to enable the conference to be run in hybrid mode. He also includes learning points from their actual experience. This advice should be invaluable for others planning similar events.
• Volker Krause, well-known in the KDE world, described his activities adding to KDE Itinerary at the recent OSM Hack Weekend in Karlsruhe.
• OSM US tooted some important deadlines for the 2023 State of the Map US. The first, for scholarship applications, had already passed on 10 March before we went to press.

switch2OSM

• Owen Boswarva noted the irony of the UK Government using a map based on OpenStreetMap to locate events around the coronation of Charles III. Over the nect 10 years, according to Peter Wells, the same government will spend almost £1,000 million making official geospatial data available to national and local government bodies.

Software

• kwiatek_123 has written osm_easy_api, which is a Python package for parsing OSM diffs and communicating with the OSM API.

Programming

• rtnf has created an interactive map of public transport routes and explained how he did it.

Releases

• Julien Minet (juminet) has compiled some details of the latest version of OpenArdenneMap, a cartographic style for topographic maps.

Did you know …

• … Simon Poole has an improved version of the JOSM presets?

Other “geo” things

• The Overture Maps Foundation is seeking an executive director to be employed by The Linux Foundation.
• This week’s #Geoweirdness thread from OpenCage was about another French speaking nation, Canada.

Mapping

• Jake Coppinger shared details on how you can create your own aerial imagery and 3D models of streets with the built-in iPhone LiDAR sensor (iPhone Pro 12 or later, 2020+ iPad Pro) and open source tools in the OpenDroneMap package. All you need to do to capture the model is walk around with your iPhone at ground level.
• Valerie Norton elaborated on her tagging issues in a national park. While normally mappers should stick to what can be surveyed in the real world, she argued that existing rules must also be considered. Some examples are service roads inaccessible to the public, or no dogs, no matter what you see people actually doing.
• The proposed feature emergency=air_rescue_service has been approved with 20 votes for, 2 votes against and 0 abstentions.

Community

• Celebrating International Women’s Day, the OpenStreetMap Blog put Geoladies PH in the spotlight – the Philippine Geoladies group.
• Pieter Vander Vennet presented some statistics from the MapComplete user survey. They include demography, computer and OSM knowledge, used themes, and feature requests.
• The old OpenStreetMap forum has now been migrated to OSM Community. Old forum links are still valid and redirect to the imported content.
• Matt Whilden is using Google Alerts to learn when town councils, or other agencies, plan to rename particular features. He encourages users to monitor the news with filters like ‘road rename’ to detect items needing updates in OSM.

OpenStreetMap Foundation

• Steve Coast posits that the OpenStreetMap Foundation has critically failed and needs a ‘reboot’. There is a poll on Twitter asking if you agree or disagree.

Local chapter news

• Joost Schouppe announced the official launch of the OSM Belgium Traffic Sign Project. It uses a continually updated traffic sign dataset from Flanders, Belgium to automatically create MapRoulette tasks to map the effect of newly digitised (and usually newly placed) traffic signs. The project was brought from proof of concept to production with help from TomTom engineers. As with similar OSM Belgium projects, it should be easy to integrate other datasets into the workflow.
• Minh Nguyen, outgoing president of OSM US, guest blogged about how the National Transportation Safety Board (NTSB) recognised communities’ efforts to ensure that railway level crossings are accurately mapped. NTSB originally wrote to OSMF, and a number of other providers of data for satnav routing, after a serious accident at a level crossing in California in 2015 (we reported earlier in #341 and #486).
• OSMCha is almost eight years old now. Running without consistent maintenance since June 2021, OpenStreetMap US has just accepted it as a charter project along with MapRoulette. Wille Marcel noted that this partnership will provide the structure to raise funds for development and hosting, and will also open the possibility for the entire OSM community to influence the future of OSMCha (Wille is the creator of OSMCha).

Events

• This year OSM Hack Weekend Berlin is taking place on 15 and 16 April. More information can be found on the OSM wiki.

OSM research

• HeiGIT announced that its ohsome R package has finally landed on CRAN. This makes it easier to analyse the rich data source of OSM history using R. You can specify your own temporal, spatial and/or thematic filters and request aggregated statistics on the evolution of OSM elements. The package can now be installed directly from CRAN.

Maps

• Paul Norman has published a new map style called Street Spirit. Its aim is to be used as a locator map. The source code is available on GitHub and a demo can also be explored.
• Amazon Web Services has announced the Open Data Maps option for Amazon Location Service, which is based on OpenStreetMap data.
• Mark Stosberg has proposed metrics for measuring where pavements (sidewalks) are most needed, based on the idea of the 15 minute neighbourhood. The code is available on GitLab for perusal.

Software

• BuntingLabs has launched an API to get map data from OSM. In their blog, they explained why it is easier to use than other existing APIs, such as overpass turbo.
• OsmAnd blogged about different terrain themes and how they can be styled in their app.

Programming

• Daniele Santini released OSM-Wikidata Map Framework, which can be used to create interactive maps that display details about entities associated with geographic features from OpenStreetMap and/or Wikidata. The types of features and entities to show are chosen by editing a configuration file and are automatically handled by the framework. The first maps to use it are Open Burial Map (shows details about people at their burial place) and Open Etymology Map (from which the framework was derived).
• For those of you who develop software that interacts with the OSM API, Paul Norman reported that the Operations Working Group is considering deprecating HTTP Basic Auth and OAuth 1.0a in favour of OAuth 2.0 on the main API, in order to improve security and reduce code maintenance.

Releases

• Organic Maps has released a new version, which features UI fixes for iOS and Android. Maps have been updated to 27 February, medicine POIs are split into several types, and more.

Did you know …

• [1] … the Belgian road completion project? It uses open government datasets to verify and detect missing data in OSM. In return, it improves the government data as well.
• … WhatIsWhere helps you to create queries like overpass turbo without a complex query language?

OSM in the media

• Frédéric Rodrigo (Osmose-QA maintainer) explored the subject of synchronising a copy of OpenStreetMap data while trying to ensure the quality of the copy. The article studies existing tools and strategies.

Other “geo” things

• heise reported ► on a project in which researchers are counting (with AI support) every single tree in a wide area of northern Africa.
• Jens Wiesehahn has created a topographic map of Germany showing soil texture, which can be viewed on Twitter.

Breaking news

• The public meeting of the OSMFoundation on Thursday, 30 March 2023 at 13:00 UTC was, as usual, only announced last Friday. Severin Menard has already summarised his remarkable thoughts on the agenda in a blog post. There are also already some reactions in the comments.

Mapping

• Valerie Norton stumbled across a horse corral (a fenced area for holding horses and other stock) and wondered how to map it. She only found one other reference in the OSM help forum, which led her to choose tourism=trail_riding_station for this particular example.
• Valerie also asked how to tag areas where camping is prohibited.
• Requests have been made for comments on the following proposals:
  • a redrafted landcover=* version 2 to formalise the usage of the key landcover=* and deprecate a number of landuse tags.
  • crossing:horn a tag on railway=level_crossing and railway=crossing nodes to denote that the crossing is subject to non-standard train horn operations.
• The proposal ► for standardising the mapping of Parque Escolar in Portugal was approved unanimously, with 9 votes in favour.

Community

• The OpenStreetMap blog reviewed the major events held by the Local Chapters and Communities WG in 2022, and provided video links to online sessions of the Local Chapters Congress held in November (as we reported earlier).
• The Trufi Association is looking for a Technical Writer / Documentation Writer to create tutorials and guides on customising their app and setting up the backend. The Trufi Association supports OSM communities, and their applications use OSM data.
• YoViajo recommended ► the use of certain tags to label health infrastructure in Bolivia. Comments added by user 5m4u9 are worth considering.

OpenStreetMap Foundation

• The OSMF welcomed TomTom, their first Platinum Corporate Member. They are happy to announce that TomTom is joining them as their first platinum tier corporate member. TomTom’s contribution provides crucial direct financial support to OSM operations and infrastructure, which is essential to accompany the growth and ensure the long-term sustainability of the world’s largest crowdsourced geospatial project. Read more on TomTom’s announcement.

Events

• The FOSSGIS 2023 conference talks are now available online.
• In 2023, OpenStreetMap will participate once more as a mentoring organisation in the Google Summer of Code, a program to bring new contributors into open source software development. Originally targeted at students, the program now also accepts people new to open source in general. Applications are open until Tuesday 4 April. Visit the GSoC 2023 wiki page to learn what the OSMF is looking for and browse their project ideas.
• The team developing the RapiD editor at Meta are hosting three days of webinars for the RapiD 2.0 launch. Each day is a webinar that is time zone friendly for Europe/Africa/Middle East (4 April), Americas (5 April) and Asia-Pacific/Oceania (6 April). The new RapiD editor will be demonstrated and Q&A with the team will follow.
• OpenStreetMap France announced that their annual State of the Map France conference will take place from 9 to 11 June in Marseille.

Education

• UN Mappers have started their training course in Portuguese. Participants got an introduction to #UNMaps, #OpenStreetMap, and the Learning Hub. The UN Mappers were excited to see what they will be able to achieve after the nine planned sessions.

OSM research

• Inspired by the Nolli map, Ester Scheck is working on the use of OSM data for mapping urban public space. She has developed a script for automated geodata processing on this topic.
• HeiGIT presented its ohsome quality analyst (OQT) software at the FOSSGIS conference in Berlin. This tool is used to analyse OSM data and see how it changes over time.
• Helga Tauscher and Subhashini Krishnakumar presented on how simplified indoor data can be extracted from digital building models. The data can be converted into formats such as CityGML or IndoorGML and used to increase OpenStreetMap’s indoor data.

Humanitarian OSM

• What’s going on in the Humanitarian Open Mapping Community? Have a look at Pete Masters’ diary.
• Pete Masters presented a really amazing video ( with subtitles) from Dr Uçum on the critical role that OpenStreetMap data has played in ensuring high quality public health programming in one of the tent cities for displaced people in Turkey as part of the earthquake response.

Maps

• Michal Paszkiewicz analysed spatial features of bus stops in London, using the TfL open data feed. He then visualised London and other places in the UK using OSM data.

switch2OSM

• AutoEvolution reported that GuruMaps now provide OSM-based offline maps for CarPlay.

Software

• The OPENER next project has set itself the goal of making public transport more accessible: especially for people who need specific adaptations related to mobility, sight or hearing. As part of this, the TU Chemnitz is developing the app OpenStop , which uses crowdsourcing to record how well developed current stops are. The idea is to ask users short and comprehensible questions about accessibility and thus improve the OpenStreetMap (OSM) dataset bit by bit, in a similar manner to StreetComplete.
• The mobile application QField is a simplified touch optimised interface for QGIS to use in the field. There is also synchronisation available, in case you are working in a team.
• Matt Whilden explained how to sort out font size problems with JOSM on Windows.

Programming

• Jochen Topf summarised his six month project to add various generalisation features to osm2pgsql. The work was supported by the Prototype Fund of the German federal government.
• Martijn van Exel experimented with asking ChatGPT to produce a Python program for extracting metadata from OSM changesets. He was pleasantly surprised by how little he had to correct and amend to get a functional program.
• Martijn was not the only person to experiment with using ChatGPT for processing OSM data. John Wiseman tried creating Overpass queries with the help of GPT-4.

Releases

• GraphHopper has released its Routing Engine 7.0. In their blog, Peter Karich presented some of the highlights: the handling of more complex turn restrictions, customisable routing, and visualising changes to areas.

Did you know …

• … FediPhoto-Lineage, the Android app to quickly post photos to the Fediverse? Here you’ll find the source code.
• … that there is a Mastodon bot that toots under-mapped small towns (fewer than 1,000 inhabitants) in the USA? The bot was created by Matt Whilden, and the code is available on GitHub.

OSM in the media

• t3n, a digital technology magazine, recommended ► two OSM-based apps (OSMAnd and Organic Maps) as alternatives to Google Maps.
• Chip reviewed ► alternatives to Google Maps for cycle touring, and liked OpenCycleMap. It is described as initially confusing, but practical and worth the download for planning purposes.

Other “geo” things

• The SwissTopo blog discussed ► the curious question of why hillshading on their national maps is lit from the Northwest. Intriguingly, the default setting for hillshade direction in QGIS is also Northwest.
• AtlasObscura showed a satellite photo of Mont Saint-Michel taken during the Autumn. The colour profile used creates an effect similar to an Impressionist painting.
• Viders Haslum, a professor of Nordic Studies, has been collecting place names in the commune of Birkenes since he was a young man. Now he has published a book based on his research, containing over 7,000 names, many in danger of being forgotten. (OSM has about 350 names associated with the ‘place’ tag, but may have more linked to woods, streams, etc.).

Mapping

• Anne-Karoline Distel (b-unicycling) has discovered milk churn stands and mapped quite a few of them.
• chris_debian blogged his thoughts about assessing road surface quality using a smartphone. He favours automated ratings by applications using smartphone sensors and lists some, for example Roadroid and SmartRoadSense.
• Risturiz explained ► how using the Fediphoto-Lineage app, a fork of Fediphoto, it is possible to preserve photos taken with StreetComplete and linked to OSM Notes.

Community

• Geoffrey Kateregga (Kateregga1) asked ChatGPT to create an OpenStreetMap Community building playbook. What it came up with is really impressive.
• The new OSM Community forum has been going for a while now, so Andy Townsend decided to summarise the pros and cons of the new software. He is happy with the functionality, but not so happy with the user experience.

Events

• Denrazir blogged about Open Data Day 2023, which was celebrated by YouthMappers from the University of Science and Technology of Southern Philippines. The theme was ‘Empowering AI and Mapping with Open Data: A training-workshop on RapID’. Denrazir was particularly pleased with the high number of women who participated in the event.
• The team at GIScience and HeiGIT looked back and commented on the many contributions made at last year’s conferences. For example, HeiGIT’s Big Spatial Data Analytics team led the Saturday workshop with ‘Analysing changes in OSM over time – full history access to OSM data through the ohsome framework’. Moritz Schott held a talk at FOSS4G presenting OSM element vectorisation and much more.

Education

• After French and Portuguese, the UN Mappers team is proposing a new free online training workshop on OpenStreetMap and humanitarian mapping in English. It is open to any English-speaking person who is new to OpenStreetMap. Registration is open until Sunday 30 April 2023, at 23:59 UTC. The workshop will be held every Thursday starting 4 May, two hours a week for 9 weeks, a total of 18 hours.

OSM research

• A team lead by Nikola Milojevic-Dupont and Felix Wagner have released EUBUCCO, a scientific database of individual building footprints for 200+ million buildings across the 27 European Union countries and Switzerland, together with three main attributes – building type, height, and construction year. OSM data are used alongside a range of national datasets.
• HeiGIT announced that osmlanduse has received a functionality update. Thanks to the cooperation of GIScience and HeiGIT under the IDEAL-VGI, HeiGIT researchers were able to add a number of new features to the interactive map. The two different data layers that make up this unique tool are now available separately for selection using the layer switcher in the top right corner.

Humanitarian OSM

• HeiGIT has set up an instance of the Disaster Portal for the earthquake affected region in Turkey/Syria in cooperation with the GIS Middle East team of Médecins Sans Frontières (Doctors Without Borders). The Disaster Portal is a service designed to support disaster relief efforts by providing up-to-date information for route planning, taking into account inaccessible parts of the road network. The underlying OSM data is updated every 10 minutes.

Maps

• Young Hahn introduced Mapbox’s 3D Live Navigation with 3D lane-level road models, live vehicle detection, landmark buildings and realistic vegetation, adding detail and clarity to the navigation experience.

Mapping

• Andres Gomez Casanova reviewed ► the different services and websites that are available to capture and store geo-referenced street-level photos in the world. Some of them, such as Mapillary, KartaView and Mapilio, allow the use of the images for OSM mapping.
• CactiStaccingCrane has started mapping the forest in the Mường Tè district of the Lai Châu province. The reason is that most of Vietnam is covered with forest and there is practically no good data in Vietnam that is suitable for import. However, he also doesn’t want to spend many more months negotiating data access with the government or organisations to improve forest mapping coverage.
• chris_debian noted 14 requirements in his ‘Thoughts on collecting road surface information’, especially for cyclists. He classified the requirements into: M=’Must Have’, S=’Should Have’, C=’Could Have=’, W=’Won’t Have’ (usually known as the MoSCoW method).
• chris66 presented ► three new 3D buildings in his blog post.
• EdoBoo demonstrated skillful micro-mapping using the example of Petronas International near Turin.
• Rabi Shrestha described how he performs field data collection and thereby ensures data quality in OSM.
• Voting on the proposal for a guide to classifying roads in Louisiana has started and will end on Wednesday 12 April.

Events

• The 2023 FOSSGIS conference in Berlin was a huge hit. The organisation has posted ► a retrospective with pictures and quick statistics on their website.
• HeiGIT has co-organised the upcoming GIScience colloquium ‘Advancing urban modelling with emerging geospatial datasets and crowdsourcing’ to be given by Dr. Filip Biljecki of the National University of Singapore. The colloquium will take place in Heidelberg in the Hörsaalzentrum Chemie, Hörsaal West, INF 252 on Monday, 24 April 2023, at 10 a.m. Much of the work is focused on OpenStreetMap and other VGI (Volunteered Geographical Information). The talk will cover recent investigations on data quality, data gaps, and understanding contributors.

Humanitarian OSM

• Samson Ngumenawe blogged about a tool under development to improve data quality for the HOT Open Mapping Hub – Asia-Pacific.
• Delphine Montagne (user Anaximandre) looked ► back at the different stages of HOT OSM data validation in order to guarantee its quality (with wonderful illustrations).

Maps

• Geofabrik, which offers daily updates of OSM data by country, has started making experimental vector tile packages available on their download server.
• Amanda McCann tooted, on Mastodon, a river basin map that uses OSM data. The source is available on GitHub.
• Walter Nordmann (Wambacher) has created a postcode map for Germany. It is intended to be used for quality analysis and troubleshooting.
• Clay Smalley posted an April Fool’s joke on the OSM Community forum.
• Supaplex found blurred but still recognisable examples of the OpenStreetMap Carto style in a discussion thread by Taiwan Infantry Command officers on the Taiwan BBS PTT military board.
• timethy96, from TheMoMStudio, has published the web app swzpln.de / opencityplans.com . It offers free access to map material. In addition to figure-ground diagrams, thematic layers such as forests or bodies of water can also be added.

Software

• Are you looking for an OSM-based vector map for cycling with turn-by-turn directions, quiet road/trail guidance, and many more details for your iPhone? Richard Fairhurst has delivered it to you. An Android version should also be available soon.

Programming

• Kai Johnson described in detail the hardware and software requirements for building a personal Overpass server on a tiny budget. mmd commented on some of Kai’s discoveries and reminded people that Overpass questions can be asked on the OSM Community forum using an ‘overpass’ tag, or on the OSM US Slack.

Releases

• OsmAnd 4.4 for Android and iOS was released on 1 April. For Android users tracks can be customised, localised POI names are available, and routes can be shared by link. For iOS CarPlay has been enhanced, hiking routes can be selected on the map, and tracks can be uploaded to OSM.
• Richard Fairhurst announced the release of Tilemaker v2.4. Tilemaker is a command-line utility that takes OpenStreetMap data in PBF format and makes vector tiles out of it. The release mainly optimises the speed of the tool.

Did you know …

• … that osm2pgsql is gradually transitioning from the use of hstore to json for storing tags?

OSM in the media

• The Polish computer portal Pure PC recommended ► alternatives to Google Maps. Many of them are based on OpenStreetMap.
• An expert policy discussion was held jointly by the Jeju Island authority and South Korea Ministry of Land, Infrastructure, and Transport to introduce the concept of ’15-minute cities’ across the island. During the discussion Kim Seonghun, team leader of the Jeju Island Urban Regeneration Support Centre, emphasised the importance of OpenStreetMap as a participatory open-source mapping platform for the foundation of pedestrian-oriented cities.

Other “geo” things

• The Canada Bay Council in Sydney, Australia plans to remove the Heath Street cycleway due to a misleading traffic report.
• HeiGIT participated in the second UN Maps Conference. Using their practical experience in working with open data, Professor Alexander Zipf and Benjamin Herfort joined in vital discussions around how to ‘build greater UN Maps’ based on open source software and open data. The conference made clear that most mapping and geospatial analysis carried out by UN organisations such as UNICEF, FAO, WHO and WFP would not be possible if OSM data didn’t exist.
• The Economist looked at the future of city grids, making extensive use of the work of Geoff Boeing (on which we have reported previously).
• Most cities do not map their own pedestrian networks. Now researchers have developed the first open-source tool to let planners do just that. MIT researchers have developed TILE2NET, an open-source tool that uses aerial imagery and image recognition to create complete maps of pavements (sidewalks) and pedestrian crossings.

Mapping

• Do you want to add improvements to OSM while out in the field? AngocA’s blog post suggests > some apps that make this possible.
• A thread on the German subforum discussed > how to map paths in boundary=protected_area that should be avoided by visitors in the winter.

Community

• [1] Daniel Capilla has added > a few more layers to his interactive map of monuments with the locations of ornamental fountains and public works of art in Málaga.
• Trufi Association is looking for a German-speaking Product Owner volunteer in the Hamburg area to promote their award-winning cycling app.

Events

• Because there is no global “State of the Map” event this year, OpenStreetMap Belgium has decided to set up a “State of the Map Europe” instead. The event will be in Antwerp, Belgium from Friday November 10th till Sunday November 12th. There will be space for 500 participants, with two main tracks, and the usual unconference part of the event. Online participation will be possible. Watch the website for further updates.
• Pete Masters is looking for suggestions for a new name for the HOT unSummit programme (there is too much confusion with the United Nations!). Token of appreciation is available, if your suggestion is chosen! Deadline 16 April.
• The key dates for SotM 2024 have been published. Venues can apply.

OSM research

• Members of HeiGIT are using gamification tools with the crowdsourcing MapSwipe mobile application to assess building completeness. OSM offers great potential to assess risk at a detailed building-by-building level, however, the completeness of OSM building footprints is still heterogeneous. This approach with MapSwipe is presented in a paper now.

Maps

• LaoshuBaby tweeted a video about how Facebook Segment Anything works on satellite imagery. The model was published on GitHub.

Software

• OpenStreetMap BaWü names (via Mastodon) the OSM apps that are already available on HarmonyOS (the OS from Huawei): OsmAnd, MapFactor, MAPS.ME, Naviki, Navmii, and Komoot.
• Achim Domma has pointed out a tweet by Katharina Nocum. In this tweet, the publicist and net activist complains that pedestrian routing wants to route her through an unlit park at 3 am. Manfred Reiter takes up the problem (in Mastodon) and refers to possibilities of improving the data through Mapathons, organised mapping like the UK quarterly project, or MapRoulette. He directly addresses the publishers of OsmAnd and Graphhopper. It will be interesting to see which app tackles this problem first, or whether Organic Maps will come out on top.
• Organic Maps reports on many new features in its 2023-04-06 release.
• News from Organic Maps reported on Mastodon. Android users can test the experimental lanes suggestion while driving. Navigation directions should display correctly on iPads now.

Programming

• Sarah Hoffmann reports on her progress with using Python for reverse geocoding on Nominatim instead of PHP.

OSM in the media

• Regional Belarusian website S13 reprints > an interview given to the corporate newsletter of the local energy grid operator by Siarhiej Dudzinski, a mapper from Hrodna, Belarus.

Other “geo” things

• Ukrainian cartographer and OpenStreetMap contributor Fedir Gontsa created detailed 3D plans of colonies on Mars. He used real data of the Martian terrain obtained by the Mars Global Surveyor unmanned research spacecraft. Open source software was used for the project.
• Ulrich et al. proposed an approach of high-resolution estimation of traffic emissions in their paper. It is based entirely on open data, such as, the road network obtained from OSM, and can be applied to other research areas within Germany with a little additional effort.

Mapping

• SherbetS documented the HIFLD dataset with a walkthrough on how to adjust this kind of file to match OSM tagging guidelines. HIFLD is a large corpus of public domain licensed geospatial information about infrastructure around the United States. Matt Whilden used this and the JOSM Conflation plugin to detect unmapped items.
• [1] Matt Whilden showed how to add 1500 addresses to OSM in 10 minutes using the JOSM Conflation plugin.
• Anton Khorev was happily surprised to find out that iD also worked on his mobile phone. In order to optimise the experience, he advises directly opening the respective frame (https://www.openstreetmap.org/id instead of the usual https://www.openstreetmap.org/edit?editor=id) which spares you losing space to the navigation bar.
• User publicerination wrote about replacing quantity=* tags on pitches in the San Francisco Bay area.
• The ‘Markers subject refinement’ proposal is open for comments. It proposes the introduction of a subset of marker=* with subject=* to allow a clearer indication of what a utility marker is referring to.
• The ‘Public Transport: Auditory Information’ proposal is open for voting until Tuesday 2 May. The proposal aims to establish multiple tags to gather different types of auditory information that may be provided at a public transport stop and/or platform.

Community

• Anne-Karoline Distel wrote about how the OpenStreetMap community actively responded to the idea of mapping milk churn stands (we reported earlier). In particular, the number of these objects mapped in Finland significantly increased after the collaboration of users houtari and Jyrki Kokko – Finnish milk churn stands are very much a thing [fi]►. Discussion is ongoing about creating a dedicated preset for the iD editor, to make it easier for beginners to map milk churn stands.
• In episode 177 of the Geomob Podcast we hear from the maker of ‘The Melbourne Map’. Steven Feldman interviewed self-proclaimed ‘accidental map maker’ Melinda Clarke.
• Growebis is looking for help in mapping buildings in Montreal.

Maps

• Knooppuntnet is an OSM-based website that documents the node networks that are common in the Netherlands and Belgium (routes for walking, cycling, horse riding and more). Check out the homepage or have a look at the demo.

Open Data

• OpenStreetMap US shared its insights on the way ahead to benefit from Public Domain and OSM data, taking into account the different licences that apply to them.

Software

• Starting with version 3.7, GDAL’s OpenStreetMap XML and PBF formats driver has a new setting to format ‘all_tags’ and ‘other_tags’ as JSON instead of hstore. In particular, users of ogr2ogr that redistribute OpenStreetMap can enable the feature, so that the recipients of the data do not need to depend on PostgreSQL or GDAL to parse the column.
• Stefan Keller [recommended>>>, a kind of ‘Street View’ for cyclists! It is open source and uses OSM data.

Programming

• Recently darkonus decided to experiment with GPT-4, a state-of-the-art language model by OpenAI, to see if it is possible to come up with a fresh approach to visualising the history of OSM data. They shared their initial attempts, examples of the traditional OSM Deep History table, and the new visualisation created with GPT-4’s assistance.
• taginfo is a long-standing OSM project that analyses OpenStreetMap tags. The developer Jochen Topf has modernised the website’s JavaScript and CSS to improve its performance and compatibility with modern web technologies. While the site’s appearance and functionality remain largely unchanged, the update paves the way for better support on smaller screens, such as mobile phones. Despite some minor issues introduced during the update, Jochen is satisfied with the current state of the website and plans to focus on content improvements in future iterations.

Did you know …

• … Notes Map ? It tries to guess what an OSM map note is about by using keywords and hashtags. To load notes, zoom in, click on Notes dazu Laden.
• … the OSM Wikidata matcher, which was recently presented by developer Edward Betts at the FOSS-North 2023 conference?
• … there is a modified version of StreetComplete called SCEE? It is aimed at experienced OSM contributors who desire advanced editing capabilities in StreetComplete and is available on F-Droid.

Other “geo” things

• Swisstopo announced ► that they will be producing a series of SoundCloud podcasts ( only). The first episode covers the development of the cartography of glaciers, lakes, and other water and wetland features. The second episode deals with the stages of the digitalisation of the main topographic maps series.
