This video animation illustrates the rapid improvement of Haïti coverage in Openstreetmap following the January 2010 earthquake. It shows the Port au Prince region, overlaid on JAXA satellite imagery. This illustrates the rapid worldwide mobilization of volunteer mappers to assist humanitarian workers on the ground.
The video is based on a Haïti extract of Openstreetmap data, made available by GeoFabrik. The animation is based on timestamps in the data (an element that has been touched several times will only appear in the animation the last time it was modified). The video is generated with a small Common Lisp program available at http://eric.marsden.free.fr/tmp/osm-h...
