OpenStreetMap (OSM) is a citizen-generated mapping platform that allows individuals to contribute geographic information.
OSM contrasts with commercial mapping services like Google Maps, which restrict access to their raw data.
The platform emerged from the need for open-license map data, with volunteers mapping areas using GPS units.
OSM has significant detail in places like London, but global coverage can be uneven.
Humanitarian efforts have utilized OSM, especially during crises such as the Haiti earthquake, where volunteers mapped affected areas for relief efforts.
OSM mapping helped organizations correlate patient origins with specific neighborhoods to address medical needs.
The platform continues to be used in various humanitarian crises, promoting on-the-ground surveys and local community involvement.
Monthly mapathons in cities like London engage volunteers in tracking satellite imagery to enhance mapping efforts.
OSM provides a valuable resource for developers and businesses, fostering opportunities in organizing and presenting open data.
The platform encourages the sharing of open data rather than hindering access to information.
