Serengeti Vegetation Map: 4 Classes
A simplified polygon file from Reed's map that reclassifies the vegetation into only four classes: forest, closed woodland, open woodland, and grassland.

NDVI Data for 2001-2010
Four files that are created processing 16-day interval NDVI (MODIS13Q1) values into annual maxima.
(1) maxNDVI_2001_2006.tif: Mean of the annual NDVI maxima between 2001 and 2006 at a pixel basis.
(2) maxNDVI_2007_2010.tif: Mean of the annual NDVI maxima between 2007 and 2010 at a pixel basis.
(3) maxNDVI_2011_2016.tif: Mean of the annual NDVI maxima between 2011 and 2016 at a pixel basis.
(4) maxNDVI_change.tif: Represents the difference between file (1) and (3).
