NAME
r.li.patchnum - Calculates patch number index on a raster map, using a 4 neighbour algorithm.
KEYWORDS
raster, landscape structure analysis, patch index
SYNOPSIS
r.li.patchnum r.li.patchnum help r.li.patchnum map=name conf=string output=name [--overwrite] [--verbose] [--quiet] Flags: --overwrite Allow output files to overwrite existing files --verbose Verbose module output --quiet Quiet module output Parameters: map=name Name of input raster map conf=string Configuration file output=name Name for output raster map
DESCRIPTION
r.li.patchnum is a patch index for r.li program. It calculates the function f(sample_area)= Patch_Number This index is calculated using a 4 neighbour algorithm
EXAMPLES
To calculate patch number index on map my_map, using my_conf configuration file and saving results in my_out file run: r.li.patchnumber map=my_map conf=my_conf out=my_out
NOTES
An that is full of null values is considered to have zero patch. If you want to have null values instead run r.null setnull=0 map=my_map after index calculation.
