About us

  • Since issue #537 we have been publishing in the Polish language. We are very happy to welcome our new colleagues and hope that this service in Poland will inspire even more people to contribute to OpenStreetMap when they can read our news in their native language. Witamy, polska drużyno. 😉


  • Pascal Neis has just updated his ‘Unmapped Places‘ using OSM data from 30 October 2020.
  • Christina Ludwig, Sascha Fendrich and Alexander Zipf report about their study on ‘Regional variations of context‐based association rules in OpenStreetMap’. This study investigates the variability of association rules extracted from OSM across different geographic regions and their dependence on different context variables, such as the number of OSM mappers.
  • The Spanish Red Cross is organising an online Mapathon (es) on Thursday 19 November from 17:00 to 19:00, to help people in Burundi vulnerable to natural disasters, armed conflict and epidemics.
  • OSM Ireland now offers a Tasking Manager that organises the simultaneous mapping of buildings close to each other, by multiple mappers, by assigning the mappers different squares to work on. Another possibility is to start your own projects anywhere in the world.
  • PoliMappers report on their effort to introduce new and interested people to the world of geospatial collaborative projects in the Politecnico di Milano campus of Piacenza.
  • Brian M. Sperlongano (ZeLonewolf) announced that his proposal boundary=special_economic_zone, to tag an area in which the business and trade laws are different from the rest of the country or state, is now open for voting until 24 November.
  • With the outbreak of COVID-19 in March 2020 the German speaking Telegram group started voting on and publishing a weekly mapping focus. Along with the German version, they recently made available an English version of their wiki page to inspire more people to contribute to the weekly changing mapping challenges. amenity=car_sharing is the current ‘Weekly Focus’. Please enter your own ideas in the ‘Focus Idea Depot’ and vote on them in the Telegram group ‘OSM de‘.


  • YouthMappers has appointed a new cohort of regional ambassadors for 2020–2021.

OpenStreetMap Foundation

  • Jonathan Beliën, one of the OSMF Microgrant Program recipients, has submitted his final report for the Road Completion Project. The project focused on software for conflating open data road networks against OpenStreetMap roads in Belgium. The code is open and can be used to achieve similar results anywhere in the world.

Local chapter news

  • Due to the lockdown in place since late October, OSM Ireland has come up with a schedule for November to make focused progress on the osmIRL_buildings project. Each day, there is a different town or group of towns to be mapped using the HOT OSM task manager.

  • Code The City’s 21st hack event invites everyone to use mapping, software, open data, or programming tools on Saturday 28 November and Sunday 29 November to create, update, digitise and modernise maps of our locales. The event will take place online and coding is, despite the name, only a small part of what is planned – take a look at the agenda here.
  • The OSM Geography Awareness Week is taking place from 15 to 21 November. ‘OSMGeoWeek’ is a week when teachers, students, community groups, organisations, and map lovers around the world can join together to celebrate geography and OpenStreetMap. Consider planning a mapathon, a webinar to show off your latest project, a career panel to talk about how your organisation uses OSM, or a workshop to teach others what you know. Follow #osmgeoweek, and share your experiences using the #osmgeoweek hashtag. When editing in OpenStreetMap add the #osmgeoweek2020 hashtag to your changesets to be included in the metrics. Add your event, or find one, at osmgeoweek.org!

  • Crowd2Map, which was created in 2015 by Janet Chapman, has enabled volunteers to map almost five million buildings in Tanzania.
