Could flood-mapping be automated? Researchers in the US have devised a flood-mapping method based on comparison of satellite images to produce almost real-time monitoring and detection of flooding. The approach was tested on the Chobe floodplain in Namibia which experiences seasonal flooding, and the method worked even where the land area was covered by vegetation.
