Serengeti dataset
Description
Vegetation data along a rainfall gradient in Serengeti national park.
Usage
serengeti
serengeti.rain
Format
A list of logical matrices
The annual rainfall corresponding to the matrices in the serengeti dataset, in the corresponding order.
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.
