Yesterday I finally filled in the last holes in building outlines and addresses. Each building has got its very own outline. There are no big blocks except for the obvious candidates: Franz-Josef-Bahnhof / WU and AKH. The latter could still be improved, but I am not sure about layering just now.
Together with all addresses (mostly as points within the building area) this is a nice step towards a complete OpenStreetMap that can be used for e.g. geocoding. I guess I achieved my 1000 addresses :)
Greetings to the other heavy building-mappers in the neighbouring districts and helping out in some areas: Dima M, ckschwoedi. Awesome work of wolfbert in the 2nd and 20th district!
