The OpenStreetMap project has been described as “wikipedia for geospatial data”. The official description is
OpenStreetMap is a project aimed squarely at creating and providing free geographic data such as street maps to anyone who wants them. The project was started because most maps you think of as free actually have legal or technical restrictions on their use, holding back people from using them in creative, productive or unexpected ways.
OpenStreetMap project contributors have mapping parties - social GPS rambles on bike or foot. Some OpenStreetMappers take a camera along and geoblog. Sounds like fun
