Okavango Delta. Vegetation cover in the Okavango delta in mid-October 1996 (NASA photograph NM22-723-083) and early July 1997 (NASA photograph NASA5-707-089). The left-hand view is a synoptic photograph of the Okavango, taken with the 100-mm lens in mid October 1996. Note that the distal ends of many of the delta fingers are dry, especially on the western side of the river. The white box on the photo depicts the area analyzed in the detailed sections on the right for change in vegetation cover between October 1996 (1840 kmē of vegetation) and July 1997 (2750 kmē of vegetation). Although many distributaries are still dry in July 1997, more vegetation filled the center part of the delta and extended farther out the distributaries, compared with the October 1996 view.
