These are unprecedented numbers. In comparison, the devastating 2010 Earthquake in Haiti attracted 500 volunteers. OpenStreetMap is showing again how an open collaboration platform outpaces closed systems in disaster response.

Within hours of the earthquake, HOT had already defined priority areas for mapping and how tasks would be distributed to volunteers worldwide using the HOT task manager. The OpenStreetMap community quickly came together in massive support, tracing out details like mountain roads, forest trails and the location of human settlements from available satellite imagery in one of the most isolated regions of the world.
Mapping Nepal with the HOT task manager.
Here are some highlights of the progress the community has made mapping Nepal.
Detailed mapping of an area of 10,000km2 in 4 days, including coverage of road networks, hiking trails, built-up areas, building footprints, river crossings and temporary relief camps
Over here at Mapbox, we’ve joined the relief effort. We’ve been helping to render imagery, map new tasks, validate contributed data, provide print maps, analyze map errors, and have kept our Bengaluru office open to the public for mapping.
