The rush for Wallonia
There is a lot going on in Wallonia! Of course the community around Arlon has a lot of activities, but now we are building contacts with the geo devision at the Service Publique Wallonie (SPW) as well.
One of the tracks is related to buildings and addresses. A few years ago, Glenn Plas built a tool to help importing the buildings and addresses in Flanders. Over the last year, he also integrated Brussels’ and Wallonian data. For the occasion, we migrated the tool to https://buildings.osm.be/ and started centralizing the documentation on the wiki. Read the wiki before trying the tool though!
