The image shows the mudflats near the island of Sylt. It was compiled from two satellite images that were taken by the German radar satellite TerraSAR-X in April and May 2008. The individual pictures are coloured red and green respectively. The difference in the reflected radar signals is especially large over the areas of water, as it is here that there were the most changes between the first and second pictures where taken; the first in April and the second in May. The blue coloured strip has been used to highlight this. The resulting image can be used to extensively study the morphology, sediments and habitats in the Wadden Sea. Structures such as tidal creek courses (recognisable in the blue area) and mussel beds (light areas near the coast) are clearly shown.
