At
Geofabrik – German for "geo factory" –, we extract, select, and process free geodata for you. We create shape files, maps, map tiles and full-blown web mapping solutions. We provide advice and training to our customers dealing with OpenStreetMap and keep them up to date.
They have several free
OSM-based tools for use - see
OSM tools, and a
download server with excerpts and derived data from the OpenStreetMap dataset available for free download. They also produced
Best of OpenStreetMap which shows places particularly well mapped on
OSM.
Interestingly they have also done
a Separate Data project to enable standard
OSM mapping while saving privacy-relevant data to a separate data base in parallel.
