HOT Red Cross mapping project 2012
The ICRC (International Committee of the Red Cross) is looking for some support from the HOT community to digitize on top of a satellite image they have acquired over the city of Tierralta. Frédéric Bonifas is a key contact point. The ICRC will use the image and the OSM tracing to work on a Water and Sanitation project.
The following is information from his mailing list post

Once a large part of the imagery is digitized in OSM, the ICRC team in Tierralta will use Walking-Papers to enhance the map with POIs and street names.
