DESCRIPTION
r.corrwindow provides information concerning the correlation
of pixels inside a moving window between two raster files.
It calculates correlation of two raster maps by calculating correlation
function of two corresponding rectangular areas for each raster point and
writing the result into a new raster map.
NOTES
This module computes the correlation between two raster files but unlike
r.pi.lm for moving windows of a specific size.
EXAMPLE
An example for the North Carolina sample dataset:
