Apply to questions about the use of openstreetmap.org the site for OpenStreetMap (OSM) a collaborative project that describes itself as “The Free Wiki World Map”.
OpenStreetMap is a free and collaboratively edited map of the world. It is designed to replace existing propriety mapping services on the Internet to support the creation of cheap GPS navigation devices and removing the restrictions placed by those propriety maps.
Users can directly edit maps on the site using a special map editor and add information about anything on the map.
