About us

  • We would like to thank everyone who sent a message on the occasion of issue 500 of weeklyOSM via blog post, e-mail, comment on the issue, Twitter or even personally. Please help to inform the community about YOUR OSM-activity by using our guest mode.


  • Joseph Eisenberg is asking for comments on his proposal of amenity=motorcycle_taxi, a specific tag for a place where motorcycle taxis wait for passengers. (Nabble)
  • Victor started a discussion asking if the presence or absence of signs for surveillance cameras should be tagged camera:signed=yes/no, as some countries require a notification if a public space is being filmed. (Nabble)
  • Long time OSM contributor Nick Whitlegg announced that he is shutting down his England and Wales footpath mapping site FreeMap. The site started out in the very early days of OSM (or even slightly beforehand) and the announcement caused Richard Fairhurst to point out a fascinating old blog post on his own mapping work antecedent to the creation of OpenStreetMap (geowiki.com) and other aspects of OSM prehistory.
  • dktue created the page autobahnkilometer.tirol on 17 February 2020 showing highway milestones in Tyrol (Austria) on a map. On the day of publication no milestones had been mapped in OSM; now most of them have been mapped.
  • Thejesh GN wrote an introduction to mapping surveillance cameras in OSM, and how to map them with OSMAnd.
  • HOT has shared about its collaboration with Microsoft on the issues of creating detailed maps of Tanzania and Uganda via satellite mapping, machine learning and community mappers.
  • Knotenpunktsystem (literally 'junction point system’) have been set up in a number of European countries to help people navigate their cycling networks by numbering the junctions and providing extensive signage between them. Robert Grübler reported (automatic translation) on the work undertaken to map the knotenpunktsystem of the cycle network in Murtal, Austria.


  • If you know a person or a project who deserves to be awarded for their contribution to OSM you can submit a nomination for the OSM-Awards 2020. Ilya Zverev asks that nominations be made before 10 May 2020.
  • Fabien Delolmo will be holding (automatic translation) a technical workshop on programming a mobile app that uses and updates OpenStreetMap data. The workshop will be held on 6 March in Grenoble, France.
  • Google announced the open source projects and organisations which have been accepted for this year’s Google Summer of Code (GSoC) program. OSM is amongst the 200 accepted open source projects. GSoC will accept student applications from 16 to 31 March 2020.
  • SomeoneElse is experimenting with adding information to established icons. Amongst other things he explains in his blog post how an icon could be enriched with wheelmap accessibility information.
  • The Tobler Society is an up-and-coming YouthMappers Chapter at the University of Chicago. They tweeted about their Mapathon, held last week. Several times a year, they host mapathons through YouthMappers’ humanitarian projects and last year students started the first chapter of YouthMappers in Chicago.

OpenStreetMap Foundation

  • Simon Poole announced a new version of the Attribution Guideline, which incorporates feedback from the public discussion in August last year. The draft will be forwarded to the OSMF board for formal approval.


  • Ilya Zverev reminds us that State of the Map Baltics 2020 will take place on 6 March 2020 at the University of Latvia.
  • Lars Linger invites you to another OSM Hackweekend on 28 and 29 March 2020 in Berlin. The event, which has been running for at least 7 years, will be hosted at Wikimedia’s offices and is supported by the FOSSGIS, the local chapter of the OSMF.
  • Ed Freyfogle, co-founder of OpenCage, and Steven Feldman, of KnowWhere Consulting, have started a podcast series about geo-related themes.

Humanitarian OSM

  • HOT has tweeted that all six HOT Microgrants candidates from Sierra Leone, Iraq, South Sudan, the Philippines, Bolivia and Peru have been fully funded by the community.


  • Do you like drawing on maps? Are you sick of having to do it on a paper map with a crayon like some sort of caveman? Then Gribrouillon (automatic translation) by Adrien Pavie is for you. Use it to draw on an OSM basemap and share with friends.
  • Andrei Kashcha announced the update of his 'obscure’ 2D WebGL renderer. In his tweet he shows a preview of the new 3D rendering feature.
  • The BBC dedicated an article to the misuse of a map to share misleading information on the global spread of coronavirus.
  • Some mappers expressed (de) (automatic translation), in the German OSM forum, their disappointment about the poor rendering performance of OSM’s main map.


  • Tempus is a transport company in the Südeifel region of Germany. With the community’s help, it has entered all of its bus lines (de) into OpenStreetMap, and built individual maps on the line pages of its website using Leaflet and Overpass.

Open Data

  • OpenDataFrance has launched (fr) (automatic translation) the GeoDataMine extraction tool. It allows local authorities to quickly extract data relating to their territory from the OpenStreetMap database.


  • OSMCha is switching its domain to https://osmcha.org. Users will be redirected from the previous domain to the new one, but developers that use the API need to change their applications to avoid problems. See more on https://www.openstreetmap.org/user/wille/diary/392289.
  • The source code for blender-osm, an add-on to render OSM data in 3D with the free and open 3D creation software Blender, is back on Github as vvoovv announced on his user diary.


  • The Open Geospatial Consortium (OGC) has announced the publication of reports documenting the work of the Open Routing API Pilot, including implementations developed and a prototype Routing API and Route Exchange Model to address location interoperability challenges with various tools available from many providers.
  • The Open Geospatial Consortium (OGC) is considering adopting CityJSON as an official OGC Community Standard. A new work item justification to begin the Community Standard endorsement process is available for public comment.


  • The JOSM team has released stable version 20.02 (release 15915) of their OSM editor. The new version brings access to Maxar’s imagery back, add links to Geofabrik’s regional/national Taginfo instances, improves JOSM’s Autofilters and has many many more new features and improvements.

Did you know …

  • … the traffic_sign tag? It allows the location and type of traffic signs to be tagged. This is especially helpful if you are unsure about how to tag the effect of the sign and helps other mappers to make corrections if necessary.

Other “geo” things

  • Omar Rizwan tweets the personalised public transport map of Auckland, New Zealand which he made for his parents.
  • Dāvis Viļums five years ago set out to ride every street in Central London. Dāvis explains the why and how and presents a time-lapse video of the record of all his rides as they reveal London’s street grid.
  • Tom Forth (ODI Leeds) has a long twitter thread (fr) about using open data to map income disparities in the UK and France.
  • Carlos Jurado Rivera was featured in an article (automatic translation) in La Voz de Almería. Carlos describes how he came to be interested in mapping the cycling infrastructure of Almería (Spain), why he chose OpenStreetMap, and his mapping style.
  • Cartographers have been known to occasionally sneak a personal joke into their work. Zoey Poll reports on how even Swisstopo has played host to a small cartographical joke or two.
  • Researchers from Heidelberg University’s GIScience Research Group have published a paper on the role of spatially structured scoring systems as a motivational element in location-based games. They found that players who are confronted with a spatially structured scoring system are more likely to have a longer playing time, walk longer distances, and be more willing to take detours than those facing a spatially random scoring system.
  • The kick-off meeting for LOKI (Airborne Observation of Critical Infrastructure) was hosted by Heidelberg University on 12 February. The aim of the LOKI project is to develop a system that enables fast and reliable airborne situation assessments following an earthquake.
  • The imagery provider Mapillary is now available in ArcGIS Urban, ESRI’s tool for smart city planning, providing imagery with street-level perspective.
