I’m sure we have all heard of the ongoing humanitarian disaster in Darfur, in the west of Sudan.

One of the aid organizations, Respond, is using satellite imagery to produce accurate maps which help address the logistical challenges in getting supplies to where they are needed. These maps have been very useful during Sudan's rainy season, when normally dry riverbeds, or wadis, flood, rather like what happens in the southwest US.

The group uses satellites from NASA and the European Space Agency (ESA).
