This map illustrates satellite detected flood water over the flood affected area in Gambia (depicted 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. This flood detection is a preliminary analysis & has not yet been validated in the field. UNOSAT is collaborating with WFP and ITHACA in support to the humanitarian operation in West Africa.
