NAME

r.pi.nlm.stats - Neutral Landscape Generator - index statistics

KEYWORDS

raster, landscape structure analysis, neutral landscapes

SYNOPSIS

r.pi.nlm.stats

r.pi.nlm.stats --help

r.pi.nlm.stats [-a] [input1=name] output=string [keyval=integer] [nullval=integer[,integer,...]] [landcover=float] [sharpness=float] n=integer method=string[,string,...] statmethod=string[,string,...] [seed=integer] [title="phrase"] [--help] [--verbose] [--quiet] [--ui]

Flags:

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

Parameters:

input1=name: Name of input raster map
output=string [required]: Name for output ASCII-file (use out=- for stdout)
keyval=integer: Value of a category from the input file to measure desired landcover
nullval=integer[,integer,...]: Values marking areas from the input file, which are to be NULL in the resulting map
landcover=float: Landcover in percent
sharpness=float: Small values produce smooth structures, great values produce sharp, edgy structures - Range [0-1]
n=integer [required]: Number of maps to generate
method=string[,string,...] [required]: Operation to perform on fragments; Options: distance, area, perimeter, shapeindex, fractal
statmethod=string[,string,...] [required]: Statistical method to perform on the values; Options: average, mode, median, variance, min, max
seed=integer: Seed for random number generator
title="phrase": Title for resultant raster map
