On the Ground

Vassar's Mapathon workshops will train on remote mapping, but anybody can be a local editor for your current location or regions you know well.

Missing Maps: How We Work - Step 1. Remote volunteers trace satellite imagery into OpenStreetMap; Step 2. Community volunteers add local detail such as neighborhoods, street names, and evacuation centers; Step 3. Humanitarian organizations use mapped information to plan risk reduction and disaster response activities that save lives.
