This map illustrates satellite-detected flood waters over the affected departments of Beni and Santa Cruz, Bolivia. Flood water analysis was conducted by change detection with MODIS satellite imagery recorded on 13 February 2008 and 27 September 2007. This is a preliminary analysis & has not yet been validated in the field.
Map scale for A3 1:2,400,000, Projection: UTM 20S.
NOTE: Because of incomplete satellite coverage, the estimated areas flooded in km2 may represent only partial values for the provinces listed, therefore it is possible that real values could be considerably higher. These flooded area estimates also may vary from earlier figures calculated from radar data collected on 3 Feb 2008, for a number of reasons, specifically: real changes in flood water extent, different areas of satellite coverage and differences in data resolution, sensor type and processing.
