  • Stefan Tauner wonders (de) > whether seasonal businesses should be mapped with two nodes. This concerns, for example, bicycle shops that become ski shops, or ice cream shops that are rented out to other businesses in winter.
  • Martin Koppenhoefer has drafted a new wiki page for tree_lined, a tag for indicating that a feature is tree lined. The tag was discussed (de) > on the German forum.
  • As part of Ireland’s 2020 Heritage Week, Anne-Karoline Distel created a video showing how to make your own heritage map for historical and heritage societies.
  • The proposed tag leisure=drawing_surface would identify walls designated for graffiti.
  • Woodpeck writes in his blog about why he is now mapping trees in OpenStreetMap and how he is doing that.


  • Kwame Odame, a doctoral researcher at the University of Cape Coast, Ghana, shared his experience working as a YouthMappers Regional Ambassador in Ghana.

  • Geoffrey Kateregga wrote in his diary about ‘The State of OpenStreetMap in Africa’, analysing among other things buildings in OSM, buildings per 1000 people, and communication channels.
  • The Times of India reports that the OSM Kerala volunteer Manoj Karingamadathil has mapped Kochi Corporation wards at the request of the Ernakulam sub-district collector. News covered by media has raised the need for more open data in India.
  • [1] Adrien Pavie is working with a small team to develop ProjetDuMois (fr) > en (project of the month) in France, to encourage thematic contributions to OpenStreetMap during a month. The website will offer the community a dashboard with contribution statistics, a web map for efficient mapping, and badges for gamification. Adrien also wrote about his experiences working with full-history OSM files to share his journey with us, hoping to make it easier for others to work with these files.


  • n76 blogged on the issues he faced while carrying out an import of buildings and addresses in Orange County, California.

  • The OSM Geography Awareness Week is taking place from 15 to 21 November. A global coalition of partners are hosting mapping events at colleges, community centres and other institutions to map places around the globe. If you are organising an event, or even just thinking about it, get in touch.

Humanitarian OSM

Matthew Gibb was re-elected as chairperson.With the principle of rotating seat elections, two Board seats were up for election this year, while next year the election will cover the other five Board seats.
  • Openstreetmap India has been active in HOTOSM. A small team has formed to create and manage HOTOSM tasks.
  • Rebecca Firth, of the Humanitarian OpenStreetMap Team (HOT), gave a TED Talk about how HOT is going to work over the next five years to support the humanitarian mapping community, with the goal of mapping an area home to one billion people.


  • The International Journal of Geoinformation (ISPRS), published by MDPI, Switzerland, invites people to submit research papers for an ‘OpenStreetMap as a multi-disciplinary nexus: Perspectives, Practices and Procedures’ issue. The deadline for manuscript submissions is 30 November 2020.


  • Supaplex explained why there is a blank area located south-east of Taiwan’s Taoyuan International Airport on most of the commercial maps available in Taiwan. There is a former military base in this blank area, the former Taoyuan Airbase of ROC Air Force and ROC Navy. The former military airport was once the home base of the Black Cat Squadron, which flew U-2 surveillance planes to investigate nuclear weapon infrastructure and capacity in China, and is mapped in very high detail on OpenStreetMap.
  • Mapbox has partnered with Zenrin to provide indoor maps for major metro stations and underground buildings in Japan.
  • Visualisations of operational sites and tactical conditions are becoming increasingly important. The fire brigade of Gossau ZH decided (de) > en to use OpenStreetMap for the creation of an emergency map. The project started with hydrants, with the intention to able to show the nearest one to firefighters as soon as possible. However, the project was quickly expanded to include additional, mission-relevant data.
  • Tatsuo Mitsuchi has created (ja) a map in which the colours are painted according to the direction of the road. The distribution of colours seems to reflect (ja) > the topography and history of the city. You can try it out on your favourite city on a test server. This system is based on city-roads.


  • Microsoft’s new flight simulator uses OpenStreetMap data to procedurally generate cities (we covered earlier). A combination of an ill-conceived university assignment, a bored student, and a typo created a 212 storey house in the outer suburbs of Melbourne, Victoria. The ‘Melbourne Monolisk’ has been attracting attention, including those who have taken the opportunity to land on it before it disappears forever.


  • Nuno Caldeira alerted Mapbox, via Twitter, that their client NOAA is using OSM maps without correct attribution.


  • Recently openrouteservice has been updated to version 6.2 by HeiGIT, which has brought some pretty useful features to OSM-based routing. One of the ‘new’ features is the re-introduction of the maximum_speed parameter so users can set the maximum speed their vehicle can travel at.
  • Dirk Stöcker announced that the OpenStreetMap Subversion repository is now read-only (we covered earlier). The JOSM and JMapViewer parts have been moved to the JOSM SVN server. For more detail see the source code and developing plugins wiki pages.
