NAME
r.li.padrange - Calculates range of patch area size on a raster map
KEYWORDS
raster, landscape structure analysis, patch index
SYNOPSIS
r.li.padrange
r.li.padrange help
r.li.padrange input=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:
- input=name
- Name of input raster map
- conf=string
- Configuration file
- output=name
- Name for output raster map
DESCRIPTION
r.li.padrange
(patch area distribution range) calculates
as:
with:
- amax: max patch area size
- amin: min patch area size
EXAMPLES
To calculate range of patch area size, using
my_conf configuration file and saving results in
my_out file run:
r.li.padrange input=my_map conf=my_conf output=my_out
NOTES
Do not use absolute path names for output files. They are raster if
moving window disposition was selected, otherwise they are in
~/.r.li/output folder.
If input raster is not full of null values r.li.padrange returns a
value >=0 that is PADcv.
If input raster is full of null values r.li.padrange returns -1.
If you want to have null values instead run
r.null setnull=-1 map=my_map
after index calculation.
