Initially the OpenStreetMap project focused mainly on surveying and collecting basic transport infrastructure (roads, paths, …) and “points of interest” (shops, facilities, …). In many countries at least the road network is very complete and we have begun to expand our focus to include a new challenge: adding address data to OSM.
At the end of August 2015 the OSM dataset for Switzerland contained a bit over 520’000 addresses, which is likely something between 1/3 and 1/4 of all addresses in Switzerland. What actually an address is and what the criteria for inclusion in an overall count is are subjects of debate and difficult to nail down, so some fuzziness is to be expected.
A large portion of the addresses have been added by classic on the ground surveying, however in some regions there are open data address sets available that can be used for quality control and in some cases are even available on licence terms that allow direct inclusion in OSM (note all imports in to OSM are subject to the import guidelines).
Open data address datasets available on compatible licence terms:
- Canton Basel Stadt
- Canton Bern
- Canton Schaffhausen
- Canton Solothurn
- City of Zürich
Open data address datasets that are available but that have incompatible (the data cannot be directly used in OSM) usage terms:
- Canton Basel Land
- Canton Geneva
- Canton Glarus
- Canton Schwyz
- City of Winterthur
Definitely no open address data sets currently available from: Canton Aargau, the Cantons Appenzell Innerrohden and Appenzell Ausserrohden together with the Canton St. Gallen, Canton Fribourg, Canton Graubünden, Canton Jura, Canton Luzern, Canton Thurgau, Canton Valais, Canton Zürich, Canton Zug.
We are in the process of doing a complete survey of the available datasets and the above lists are not complete at this point in time.
