DESCRIPTION

This module computes the correlation between two raster files but unlike r.pi.lm within a moving window of a specific size. This module is partly based on r.neighbours and r.covar.

EXAMPLE

An example for the North Carolina sample dataset: Correlation of all pixels within a 7x7 sized window of two rasters (elevation and slope). The output is multiplied by 10000 for 
r.pi.corrwin input1=slope input2=elevation output=corrwin1 size=7 max=10000
r.colors corrwin1 col=bgyr

SEE ALSO

r.pi.index, r.pi.lm, r.pi
