This Envisat composite image shows the French island of Corsica, one of the largest islands in the Mediterranean Sea. Corsica is located just 90 km west of Italy, and 170 km south of France. Sardinia is just to the south across the Strait of Bonifacio, and we can see a couple of Sardinian islands along the bottom of the image. In the top right corner we can see the Italian island of Capraia.
This image was created by combining three Envisat radar acquisitions (3 January, 2 February and 2 April 2012) over the same area. The colours result from changes in the surface between acquisitions.
