The Missing Maps project, which launched in 2014, aims to literally and figuratively put more than 20-million at-risk people on the map using OpenStreetMap (OSM) as a platform. We need to fill in "missing maps" before the next disaster strikes, ensuring the maps have detail sufficient for emergency responders to hit the ground running.
OpenStreetMap is an open and free source of geographic data. Anyone with a username can add, edit, or update data, so the Missing Maps project is community driven and focuses on local knowledge. Remote volunteers around the world use satellite imagery to trace features, such as roads and buildings.
