Join us virtually with UCLA and SC mappers in our 4th annual humanitarian mapathon challenge to make entries on the OpenStreetMap platform in support of priority humanitarian relief efforts around the world!

Last year’s mapathon was one of the world’s largest single-day events with 150 mappers collectively mapping 17,126 buildings. Help us break our record by mapping more than 20,000 buildings this year over 3 days. See the mapathon schedule below.

No GIS skills are required! We will quickly train you to use OpenStreetMap (OSM) to assist in humanitarian projects around the world.
