The Missing Maps project maps the most vulnerable places in the developing world.  Building on the excellent work done by the Humanitarian OpenStreetMap Team (HOT) and others in mapping as emergency response, the Missing Maps Project aims to map the places in the world where the most vulnerable people live in a proactive way. Instead of responding to a natural disaster, conflict or epidemic, regions vulnerable to crises are identified and mapped in anticipation of crises, meaning that when one occurs, local people, NGOs and other responders can start using the maps and the data from the word go, saving valuable time, and potentially, lives.The Missing Maps Project is an open collaboration founded by the American Red Cross, the British Red Cross, Humanitarian OSM Team (HOT) and Medecins Sans Frontieres/Doctors Without Borders (MSF).
