Acquired: 07/03/2006 and 18/09/2007
Satellite-detected flood water over the flood-affected area near Kaolack, Senegal (in red). Flood water analysis was made using a multitemporal composition of ASAR radar data recorded on 18 September 2007 and 7 March 2006. The multitemporal composition was produced by ESA on behalf of the Space Charter. Additional MODIS terra data from September 2007 was used in this analysis. Preliminary analysis not yet validated in the field.
