A range of Astrium satellites has been closely monitoring the Australian State of Queensland. Affecting an area the size of France and Germany put together and killing more than 30 people since heavy rains began last November, the floods have been the worst the state has seen in decades.
This multi-temporal false colour image was acquired by Envisat’s onboard ASAR instrument, working in wide swath medium resolution mode, earlier this month. The inundated area, south of Rockhampton, is represented by the blue colour.
The above images are a comparison of pre- and post-event radar images from TerraSAR-X (left) and TanDEM-X showing the extent of the flooding of Australia’s Fitzroy River.
This image captured by the SMOS satellite shows soils containing more than 40% water (dark blue).
SIS, an Astrium subsidiary in Australia, re-tasked the Spot constellation to monitor the floods, in response to requests from Queensland’s civil defence services and Geoscience Australia.
