About us

  • weeklyOSM collects relevant OSM news from all over the world and informs the community every week. We announce each new issue via Twitter, Mastodon, mailing lists, Telegram, and we also want to announce it at community.openstreetmap.org.However, some mailing lists are relatively low volume, and list admins may wish to limit how many ‘weekly’ announcement messages appear there. If that is the case, could list admins please let us know via ‘lists at weeklyosm.eu’?

Mapping campaigns

  • User sahilister reported, in his blog, about his systematic mapping of schools in Chandigarh, North India.


  • LuxuryCoop presented (ko) > en use cases for the place tag in Korea and suggestions for improvement.


  • Hayden Clarkin discovered that using overpass turbo makes it easy to analyse parking space land use, and asked how to find other cool OSM tools.

OpenStreetMap Foundation


  • European deputy Anna Deparnay-Grunenberg, made official (de) / (fr) > en the Bio.Vélo.Route., a cycle route from Stuttgart to Strasbourg celebrating the 60th anniversary of their town twinning. As shown on the website, the route made full use of OpenStreetMap data through Komoot and uMap. A route relation stub has been created and may benefit from contributions along it.
  • Tracestrack has released an Osm-Carto/OpenTopoMap hybrid map style. With a demo page using Mapbox Globe, it shows the OSM-Carto style enriched with colour relief, hill shades and contour lines from OpenTopoMap. As a background layer, various existing label layers can be overlaid.


  • Sarah Hoffmann described how type annotations have been added to Nominatim’s Python code in order to improve software maintainability, and also explained some lessons she learned in the process.
  • korobkov outlined a five-step workflow which allows you to quickly complete a series of similar MapRoulette tasks for OpenStreetMap using the keyboard only, with little to no manual intervention, in a matter of seconds per task via browser automation plug-ins using regular expressions.
  • PhysicsArmature suggested a design for a JOSM extension to map a large area of something that has distinct colour.
