Torrential rains and floodwaters from rivers that burst their banks, have destroyed homes and left over 70% of Mexico's southern State of Tabasco under water. Villahermosa, the capital city of Tabasco has seen flood waters as high as 18 feet. Over 1 million people in the region have been affected.

Using pre-flood data and current RADARSAT-1 data, an image showing flooded areas in the region around Villahermosa was created (below). In this image, areas of change (flood) are shown in blue. The flood extents were derived by performing a change detection analysis using RADARSAT-1 archive data (Jan. 7, 2007, Wide beam mode) and a newly collected scene (Nov. 6, 2007, Standard beam, mode).
