About
OpenStreetMap is a community-driven, open-source world map built and maintained by volunteers who contribute geographic data such as roads, trails, and points of interest. The map data is freely available under an open license and powers thousands of websites, mobile apps, and hardware devices. It is operated by the OpenStreetMap Foundation on behalf of its global contributor community.
Problem
Proprietary map data is expensive and restrictive, limiting access to geographic information for individuals and organizations.
For
developers, GIS professionals, and anyone needing free map data
How it works
Volunteers contribute and maintain geographic data using aerial imagery, GPS devices, and field maps, which is then made freely available under an open license.
