About us

  • Attention Telegram-Group admins: Matthias, from the weeklyOSM team, has created a Telegram-Bot. The bot does nothing more and nothing less than announce the publication of new issues of weeklyOSM – usually on Sundays.If you are interested in using this service for your Telegram group, an admin must add this bot as a member of the group. After that, a message to info @ weeklyosm dot eu is necessary so that Matthias can make your Telegram group known to the bot. The following Telegram groups have already joined OpenStreetMap, OpenStreetMap India, OpenStreetMap Korea, and OpenStreetMap Taiwan.


  • French OSM mappers are having a discussion about mapping advanced stop lines (cycleway=asl), especially the elements’ order where traffic lights are separately mapped. LeJun asked about it on the wiki but received only two opinions. If you have one, feel free to share it. A proper proposal for this tag might be necessary in the future.
  • Kai Johnson has been using the US Bureau of Land Management’s transportation dataset to fill in backcountry routes in Southern California. Their diary post explores some of the difficulties encountered.
  • Martijn van Exel gave us an update on his October OSM-related activities.
  • The following proposals are waiting for your comments:
  • Voting is underway for the following proposals:
    • highway=scramble, for indicating that a path needs use of hands to travel over, until Tuesday 22 November.
    • Standardising the tagging of manufacturer:*=* and model:*=* of artificial elements, until Sunday 27 November.
    • archaeological_site=*, to replace the site_type=* key for tagging the type of archaeological site.


  • OSM user fititnt has proposed an idea on how to improve the quality of OpenStreetMap data access by using semantic web technology.

OpenStreetMap Foundation

  • The Foundation members will vote in December to elect four new board members from 11 candidates. The Candidates’ answers to official questions and manifestos are now available. More information about the Board election is available on the OSM wiki.The election will be followed by the Annual General Meeting of the OpenStreetMap Foundation (OSMF) that will be held online in the IRC chat room on Saturday 10 December 2022 at 16:00 UTC.



  • Dongha Hwang (LuxuryCoop) has made a map showing all the names that include either of the two Korean words (‘sageori’ in blue dot, ‘negeori’ in red dot) that mean ‘crossroad’ using overpass turbo and MapCSS. 카토그램 has made a set of maps showing n-way intersections (n from 3 to 10) in South Korea.
  • The OpenIndoor map will help you see the insides of buildings if they are described in the OSM database. Of course, it does not tell (yet…) how many cabinets and TVs, or other interior elements, are inside, but it can provide information about the number of floors and where the stairs and doors are located. More details about this project are available on GitHub.
  • Peter Karich, co-founder of GraphHopper, announced the release of GraphHopper Maps, a web-based route planner powered by the GraphHopper routing engine.


  • The GeoDesk team announced their release of a new spatial database engine, designed specifically for OpenStreetMap data. Key strengths include cross-platform support, a compact file format, fast imports, queries that are 50 times faster than SQL, full support of OSM features (including relations), and modest hardware requirements. You can build geospatial applications based on the GeoDesk Java toolkit, or use the standalone utility to query OSM features and export them in a variety of other formats. GeoDesk is free and open source.
  • For users that are experiencing problems updating the official Java release from Oracle, rtnf has described how he updated Java on his computer to use the ‘Azul Platform Core’ package instead of Oracle’s and thus get rid of the deprecation message at JOSM startup.


  • The French government recently voted for the systematic use of photovoltaic panels on parking lots with a capacity greater than 80 places. Christan Quest has run a quick fetch of the OpenStreetMap data in Île-de-France and found 1806 parking lots totalling 5,000,000 m². Further calculations lead to an estimated possible energy production of 1 TWh / year, enough for about 1% of the region’s population.


  • The November release of Organic Maps (OSM based) is available for iOS and Android. Some important changes are fixes for handling KML files, detection of current position, and showing speed cameras on tap. As always map updates, bugfixes in search and routing and improvements in translations are included.
  • [1] Pascal Neis’ ‘Unmapped Places of OpenStreetMap‘ has just been updated with the latest OSM data. The map shows village nodes (place=village) that don’t have any streets (residential, unclassified or services) within a 700 m radius. As noted in the comments, it’s also useful as a place to discover poor-quality imports that should be reverted.

Did you know …

  • … the two articles about osm2pgsql / postgis programming from Jakob Miksch How to replicate an OSM database (the easy way) and How to convert polygons to points (suggested by bufferclip) ?
  • … there is a web application that shows charging stations for electric cars in Germany? You can switch between the data bases [B]undesnetzagentur (Federal German Net Agency) and [O]SM.
  • … that the right and left banks of rivers match the perspective of a vessel drifting with the flow of the river? This perspective sometimes leads to the right bank of a river being on the left side of a map of that river, usually when the river flows north to south, such as the Dnipro does.
  • … the daily word puzzle ‘Wordle’? You can test your geographical knowledge with Worldle, which also offers you six chances to guess correctly. There’s now an FAQ on the site, including details of how to access previous puzzles.

Other “geo” things

  • Climate TRACE has released a interactive map of greenhouse gas emissions worldwide. The data shown comes from multiple sources including satellites, sensors, public and commercial datasets.
  • Great Britain’s Ordnance Survey (formerly a government department, now a government-owned company) has commented about how the direction of Magnetic North (as viewed from Great Britain) is moving, East across the UK. Magnetic, Grid, and True North will align along a line running from Langton Matravers to Berwick-Upon-Tweed over the 12 months from August 2023.
  • You can watch The Map, a 10 minute documentary about the redesign of New York City’s iconic subway map.
