This map illustrates a time series analysis of satellite-detected areas of flood waters and flood affected land around the Phnom Penh, Cambodia using Landsat-8 sata acquired 24 October 2013 andTerra-SAR data acquired 23 October 2013. Seasonal floods have caused heavy flooding in the region. The arrival of Typhoon Nari increased the heavy rains resulting in flashfloods. It is likely that flood waters have been systematically underestimated along highly vegetated areas along main river banks, and within built-up urban areas because of the special characteristics of the satellite data used. This analysis has not yet been validated in the field. Please send ground feedback to UNITAR /UNOSAT.
