Note: This document is for an older version of GRASS GIS that will be discontinued soon. You should upgrade, and read the current manual page.

NAME

r.pi.prox - 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.

KEYWORDS

raster, landscape structure analysis, proximity analysis

SYNOPSIS

r.pi.prox

r.pi.prox --help

r.pi.prox [-a] input=name output=name keyval=integer method=string [min=integer] [max=integer] [title="phrase"] [--overwrite] [--help] [--verbose] [--quiet] [--ui]

Flags:

-a: Set for 8 cell-neighbors. 4 cell-neighbors are default
--overwrite: Allow output files to overwrite existing files
--help: Print usage summary
--verbose: Verbose module output
--quiet: Quiet module output
--ui: Force launching GUI dialog

Parameters:

input=name [required]: Name of input raster map
output=name [required]: Name for output raster map
keyval=integer [required]: Key value
method=string [required]: Operation to perform on fragments; Options: proximity index, modified proximity index, neighborhood index
min=integer: Minimum range for the operation measured by pixels, default 0
max=integer: Maximum Range for the operation measured by pixels, default copmlete map
title="phrase": Title for resultant raster map
