In January, 2011, Australia's northeastern state of Queensland was subjected to historic flooding along many coastal rivers. This was a result of a wet spring followed by extreme rain events over Christmas and in early January. September to November was the wettest spring since records began 111 years ago, according to the U.S. National Oceanic and Atmospheric Administration's (NOAA) National Climate Data Center. The floods have affected over 200,000 people and an area roughly the size of France and Germany, according to the Australian Bureau of Meteorology.
RADARSAT-2 change detection
A change detection procedure was performed on an image from January 7, 2011 (the 'after' image) and an image from April 9, 2010 (the 'before' image). Flooded areas are highlighted in yellow. This product was developed by Dendron Resources with the support of the CSA Earth Observation Applications and Utilizations Division.
