Open-source project treads on Google Maps turf

The U.K.-based OpenStreetMap (OSM) mapping data is collected by volunteers using GPS devices to record their movements as they drive, cycle or walk along all the roads in a particular area.

OSM's Web site has the same layout and background as Wikipedia pages because it uses MediaWiki, free wiki software wiki originally written for Wikipedia. OSM, however, is not a project of the Wikimedia Foundation, which is the parent organization of Wikipedia.
