Hello,
I have created two video animations that illustrate the rapid
improvement of Haïti coverage in OSM following the earthquake. One shows
the Port au Prince region, overlaid on JAXA satellite imagery :

and the other the entire island of Hispanolia

I think these illustrate the rapid worldwide mobilization of volunteer
mappers to assist humanitarian workers on the ground.
The videos are based on the timestamps in GeoFabrik's 20100123 Haïti
extract (an element that has been touched several times will only appear
the last time it was modified). They are generated with a small Common
Lisp program available at
