A Humanitarian OpenStreetMap (HOT) Team was deployed to Port au Prince last night with all the equipment needed to train earthquake responders on OpenStreetMap. Essentially, OpenStreetMap is a free, editable map of the whole world. Why does this matter to Haiti? OpenStreetMap, being available to everyone without cost, provides a mechanism for humanitarian responders and development actors to rapidly share geographic information. The HOT team will spend the next several weeks in Port au Prince helping to bring this about.
