Description
Vegetation data along a rainfall gradient in Serengeti national
park.

Format
A list of logical matrices
Details
The data-set consists of a rectangular area of size 7.5 km x 90 km.
These data are represented as a list of matrices. Each matrix is a moving
window of 7.5 km x 7.5 km which moves my 2.5 km along the length of the
rectangular data-set.
Each entry in the matrix is vegetation data at a resolution of 30m as
classified into binary units with 0 (grass) and 1 (forest).
The rainfall data provided here is the average rainfall (mm/yr) of a
moving window of dimension 7.5km which moves my 2.5 km along the length
of the rectangular data-set.
