28 Mar 2008 description

This map illustrates satellite-detected flood waters as of 25 March 2008 over the affected areas of southern Angola. Detected flood waters are shown in red. Flood analysis was made using DMC data recorded 25 March 2008 at a spatial resolution of 30 meters. Note: Differences in the flood extent between earlier flood maps do not necessarily indicate significant changes in water levels but may be due to differences in the spatial and spectral resolution of satellite sensors. This flood detection is a preliminary analysis & has not yet been validated in the field.

26 Mar 2008 description

This map illustrates satellite-detected flood waters as of 20 March 2008 over the affected areas of southern Angola. Detected flood waters are shown in red. Flood analysis was made using Radarsat data recorded 20 March 2008 at a spatial resolution of 25 meters. Note: the flood water extent shown in this map is significantly greater than the extent shown in the previous flood detection map (version 1.0) published 20 March 2008. This difference thus does not indicate an absolute increase in water levels but is due to differences in the spatial and spectral resolution of satellite sensors.

20 Mar 2008 description

This map illustrates satellite-detected flood waters as of 19 March 2008 over the affected areas of southern Angola. Flooded areas have been sorted into 2 classes: Red areas represent standing flood waters identified with a high degree of confidence; and Blue areas represent pre-flood water levels in July-November 2007. Flood analysis was made using ENVISAT-ASAR data (WSM) recorded on 19 March 2008 at a spatial resolution of 150m, and MODIS recorded in November 2007 and March 2008.This flood detection is a preliminary analysis & has not yet been validated in the field.
