Value to be set for the correlation value 1.0 in order to receive more information of the decimal places, e.g. set it to 1000
title="phrase"
Title for resultant raster map
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
