OpenStreetMap (OSM) is a free, open geographic database updated and maintained by a community of volunteers via open collaboration. Contributors collect data from surveys, trace from aerial imagery and also import from other freely licensed geodata sources. OpenStreetMap is freely licensed under the Open Database License and as a result commonly used to make electronic maps, inform turn-by-turn navigation, assist in humanitarian aid and data visualisation. OpenStreetMap uses its own topology to store geographical features which can then be exported into other GIS file formats. The OpenStreetMap website itself is an online map, geodata search engine and editor.
OpenStreetMap was created by Steve Coast in response to the Ordnance Survey, the United Kingdom's national mapping agency, failing to release its data to the public under free licences in 2004. Initially, maps were created only via GPS traces, but it was quickly populated by importing public domain geographical data such as the U.S. TIGER and by tracing permitted aerial photography or satellite imagery. OpenStreetMap's adoption was accelerated by Google Maps's introduction of pricing in 2012 and the development of supporting software and applications.
The database is hosted by the OpenStreetMap Foundation, a non-profit organisation registered in England and Wales and is funded mostly via donations. Meta (formerly Facebook) launched its distribution called Daylight, based on OSM in 2020. The Linux Foundation's Overture Maps Foundation released their first open map data based on OSM and other sources in July 2023.
