  • Russell Deffner starts a second RFC for the proposed shop=cannabis tag.
  • The voting phase on the proposal about aviation obstacle lights is currently open. This proposal involves the precise tagging of lights on tall obstacles (towers, buildings), that work as collision avoidance for aircraft in flight.
  • Another proposal on the subject of contractors, for example for the construction of an office building, was published by Christopher Baze as a tag contractor=. The voting is open until April.
  • Carlos Brys, from Argentina, reopens the discussion in the forum about the tags for various paving types, especially the “Brazilian” type (a variant of the Portuguese paving) which was previously mentioned on the Tagging mailing list.
  • Geochicas launched their project on Twitter called #LasCallesDeLasMujeres (the streets of women), in which they generated a map to analyse the gender balance in street nomenclature in Latin America and Spain, linked to the Wikipedia biographies of women who have a street named after them.
  • The proposal about pedestrian connections between ski lifts and pistes has been approved.
  • Strava has updated its heatmap imagery.
    Besides not displaying places with very little activity, the maximum zoom level is now limited to 12.
    It will be harder to trace or align ways in most cases due to the heavily pixelated heatmap.


  • OpenStreetMap has reached one million registered map contributors!
  • Geohipster interviewed someone behind the Twitter account Anonymaps.
  • Levente Juhász tweets about his new open-access publication about OSM contribution patterns and how to foster long-time mappers.
  • Maurizio Napolitano (user napo) published a proposal on the Wiki for “Mappers in Residence”. This suggests replicating in OSM the Wikipedian in Residence experience: a volunteering idea designed to help institutions or companies donate their information to the open knowledge world.
  • “OpenStreetMap, MapaNica and the Buses in Nicaragua” is the title of a presentation recently held in Esteli, Nicaragua, that explains the mapping process of bus routes in Managua and Estelí. More info is available on the event’s blog post.
  • OpenCageData interviewed with Andy Mabbett, who is active in both Wikidata and OpenStreetMap communities. He speaks about the connections between the two.
  • Valentina Carraro and Bart Wissink wrote a paper about minorities’ under-representation on OpenStreetMap, and the risk of real-world inequalities seeping into potentially democratic crowdsourced projects. The full article is behind a paywall.


  • In Portugal, massive data seems to have been imported for two months without prior agreement nor documentation.
  • Ilya Zverev got ahold of NavAds dataset of over 59K fuel stations worldwide. Data are currently being reviewed and prepared for the import – the progress can be followed on the Import mailing list and on the dedicated wiki page.

OpenStreetMap Foundation

Humanitarian OSM

  • The “Asia Foundation” shows in a photo blog how the Nepalese community celebrated Open Data Day. Kathmandu Living Labs organized a mapathon where many participants were introduced to the possibilities of OpenStreetMap.



  • A history analysis platform for OpenStreetMap is currently being developed at HeiGIT. It will make OSM data from the full history of edits more easily accessible. Check out the project‘s first ohsome Nepal Dashboard preview.
  • An OSM map as wallpaper on your smartphone? This web service operated by Alvar Carto makes it possible.
  • In a report (de) (automatic translation) the Potsdamer Neueste Nachrichten describes the start-up Calimoto. Their navigation app for motorcyclists is characterised by its preference for curvy routes.
  • In the OSM-Forum a new editor was introduced, which can primarily add new 3D buildings. It comes from the creators of PlaceMaker, a paid plug-in for SketchUp that imports 3D geodata into SketchUp and prepares it. The developers also uploaded a tutorial video.


  • Starting May 1st, the public Geofabrik downloads will no longer contain metadata about OSM users. Accessing the complete extracts will require logging in with an OSM account.

Did you know …

  • … a script to show the results of a database query in a map?
  • … the flosm OSM theme maps? There’s a new site to create your own individual map themes.
  • OpenMapTiles? Here you can create vector world maps with a set of tools, which you can use for hosting or offline use. The program is available as free software at OpenMapTiles.org.
  • … this video that illustrates our mapping activity in OpenStreetMap since 2006?

OSM in the media

  • An article by CityLab on the gender distribution among mappers is being discussed on the diversity mailing list and Reddit. While commenters extend a welcome to mappers of all genders and backgrounds, the statistics cited in the article are met with scepticism.

Other “geo” things

  • Google Maps is following OSM and now also offers data for wheelchair users. For the time being, however, only in selected cities and with a lot less information than OSM has available.
  • According to a World Bank estimate, half of the world’s urban population lives on unnamed streets. The “Plus-Codes” from Google are an alternative to the usual addresses (city, street, house number). But it is also an alternative to proprietary systems like “what3words”.
  • Google wants to make it easier for game developers to create games similar to Pokémon Go using the Google Maps API.
  • In an article on SciDev, the principles of humanitarian mapping are discussed.
