This map
illustrates satellite detected flood water over the affected district of Larkana, Sindh Province, Pakistan (depicted in blue). Village site locations within 500m of detected flood water are marked in
red, while those more than 500m are marked in green. This analysis was made using ALOS-PALSAR and Radarsat data recorded respectively on 26 June & 5 July 2007. Additional pre-disaster ENVISAT
radar data from 25 April 1999 was used in this analysis. This flood detection is a preliminary analysis and has not yet been validated in the field. This map was produced through a joint collaboration
among UNOSAT, WFP and ITHACA.
FLOOD ANALYSIS: (within map extent):
