The Normalized Difference Vegetation Index (NDVI) shows the distribution of vegetation across Central Africa. The most densely vegetated areas are dark green, and regions with little or no vegetation are gold. The NDVI image correlates well with the true-color image that accompanies it. The dark green area surrounding the Uele River, which forms the border between the Central African Republic on the north and the Democratic Republic of the Congo on the south is correspondingly green in the true-color image.

The two images also show Central Africa’s three biomes. On the top is the Sahara Desert with little vegetation. To its south are the grasslands of the Sahel. In the lower section of the images is the rainforest surrounding the Congo River. The Congo itself forms an upside-down “u” in the bottom center of the image.
