NAME¶
r.li.dominance - Calculates dominance's diversity index on a
raster map
KEYWORDS¶
raster, landscape structure analysis, diversity index
SYNOPSIS¶
r.li.dominance
r.li.dominance help
r.li.dominance 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.dominance calculates the "dominance's diversity index" as:
with:
- m: number of different patch type
- i: patch type
- pi: proportion of the landscape occupied by patch
type i
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 full of null values r.li.dominance returns -1.
If you want to have null values instead run
r.null setnull=-1 map=my_map
after index calculation.
EXAMPLES¶
To calculate dominance's diversity index on map my_map, using my_conf
configuration file and saving results in my_out file run:
r.li.dominance map=my_map conf=my_conf output=my_out
