About

Free, up-to-date maps are a critical resource when relief organizations are responding to disasters or political crises. The Humanitarian OpenStreetMap Team (HOT) creates and provides those maps.


  • Collaborative Maps for Humanitarian Aid

    Reaching those in need through maps

    When major disaster strikes anywhere in the world, HOT rallies a huge network of volunteers to create, online, the maps that enable responders to reach those in need.

    Putting the world's vulnerable people and places on the map

    Many of the poorest and most vulnerable places in the world do not exist on any map. To data over 3,500 Missing Maps volunteers have collectively made 12 million edits to OpenStreetMap and put 7.5 million people on the map.


  • Community
