The image of Ukraine shows how a radar satellite perceives fields and forests. The satellite imaged a reservoir near the River Donets, a tributary of the Don. Forests and agricultural land surround the reservoir. These areas are worked differently, and thus exhibit differences in the way they reflect radar signals. This variable surface structure is revealed in the image by different brightness levels and colours. East of the smaller reservoirs near the centre of the image, a moving train is visible as a bright, curved line. From the offset of the train on the tracks, seen from space, it is even possible to calculate its speed.
