OpenStreetMap (OSM) is a collaborative project to create a free editable map of the world. It uses a wiki-style editing environment where volunteers can contribute geographic data that is licensed under an open database license. The document discusses how OSM data can be contributed and edited in a variety of ways, both online and offline. It also outlines how OSM has been used for humanitarian mapping efforts.
