What is OpenStreetMap?

Answer

OpenStreetMap (OSM) is a free, open geographic database updated and maintained by a community of volunteers via open collaboration

.
It was created in 2004 by Steve Coast in the UK, initially in response to the Ordnance Survey's failure to release its data under free licenses

.
The project has since grown to include data about roads, buildings, addresses, shops and businesses, points of interest, railways, trails, transit, land use, and natural features

.
Key aspects of OpenStreetMap include:
  • Volunteer-driven: The map is created and maintained by nearly 5 million registered users and more than 1 million map contributors
    3
    .
  • Local knowledge: Contributors use aerial imagery, GPS devices, and low-tech field maps to verify that OSM is accurate and up to date
    5
    .
  • Open data: OSM is freely licensed under the Open Database License, allowing it to be used for various purposes, including turn-by-turn navigation, humanitarian aid, and data visualization

    .
  • Community-driven: The diverse and passionate OSM community includes enthusiast mappers, GIS professionals, engineers running the OSM servers, and humanitarians mapping disaster-affected areas

    .
OpenStreetMap is used by local people, volunteer groups, companies, governments, and software developers, and provides map data for thousands of websites, mobile apps, and hardware devices
