Like Simon has already noted in a previous blog entry, we may use the Building Addresses of the Canton of Bern (GEBADR) for OSM.
In the last months the data was prepared to be suitable for OSM and a tasking manager was set up. Further information can be found in the documentation on the OSM wiki about this project.
Some are already mapping the addresses and are drawing the missing building outlines. But the task is rather large with a total of 400’000 addresses and it will take a long time. Further mappers supporting this project would therefore be really welcome. So please spread the word!
A special thank to Michael Spreng for his support and setting up the tasking manager. The tasking manager was set up on the servers of SOSM and is now available for other projects as well.
