The image, taken by the German radar satellite TerraSAR-X, shows the mangrove-covered islands of the Bakassi peninsula, which are situated at the extreme eastern end of the Gulf of Guinea. Due to the outstanding accuracy of its calibration, TerraSAR-X is able to detect very small changes in the returned signal caused by changes in vegetation or deforestation. By monitoring endangered mangrove forests all over the world, TerraSAR-X can support biodiversity preservation activities. The image was taken on 2 June 2008. It was acquired in stripmap mode with a resolution of 3.3 metres. Compare with a similiar photo in visible range.
