OpenStreetMap Rallies for Nepal

As reports came in on Saturday that Nepal was hit with the biggest earthquake since 1934, the Humanitarian OpenStreetMap Team (HOT) immediately rallied the OpenStreetMap community. Since then, thousands of people have started mapping.

OpenStreetMap updates in real time. By using OpenStreetMap data, disaster response teams on the ground and organizations like the UN, the Red Cross and Katmandu Living Labs have maps to help the eight million people affected by the earthquake.

Unprecedented numbers

In only 48 hours after the quake, over 2,000 mappers quadrupled road mileage and added 30% more buildings. This is in addition to the great data created by the local community well before the quake.

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

Emergency activation

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.

Highlights

Here are some highlights of the progress the community has made mapping Nepal.

Our involvement

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.
