OpenStreetMap: Hamburg almost complete

The Hamburg participants of the collaborative world map OpenStreetMap (OSM) have proved themselves as especially diligent at collecting geo-data.

On the go for about the last four years, this Web2.0 map project aims to establish a free, open database with map data covering the entire globe (see our post).  As announced by the Hamburg OSM-Community in a press release, nearly 8,000 streets of their city have been documented, thereby becoming the first large German city to have all of its streets registered in the freely available world-map.

For the purposes of checking the accuracy and completeness of the OSM listing, a comparison has been made with the Hamburg Street and Area Directory of the Hamburg Statistics Division, resulting in a 99,8% overlap in accuracy. Still, there’s a lot still to be achieved by the Hamburg OSM team to cover small foot and cycle paths.  And the surroundings are still showing many white patches of undocumented areas.
