|Flooding in Rome, Italy, mapped by RADARSAT-2|
Heavy rain occurred in the second week of December 2008 in the Rome area.
The river Aniene, a tributary of Tiber, flooded several flat areas around its riverbed.
RADARSAT-2 acquired a fully polarimetric image in the morning of 13 December, when water covered the surface. A comparison of the 13 December image with one previously acquired (in October 2008) allowed the flooded areas to be mapped in near-real time through a change detection technique.
The images, utilizing GoogleMap (©2008 Google) show the flooded areas (in blue) around the Aniene river as obtained by the RADARSAT-2 SAR images.
