A satellite image of Namibia with a color gradient overlay corresponding to vegetation coverage. Vegetation coverage ranges from dark brown to dark green with white being the average between them. The Etosha Pan, bottom right, and the Natukanaoaka Pan, center left, are the two biggest areas in the brown shade. The image is primarily a shade of green to white with scattered brown spots. The Ekuma river enters the image at the top center, and does also carry some brown coloration where the water covers the land.
