ОПИСАНИЕ

r.li.padrange (patch area distribution range) calculates as:

with:

ПРИМЕРЫ

To calculate range of patch area size, using my_conf configuration file and saving results in my_out file run:
r.li.padrange map=my_map conf=my_conf output=my_out

ПРИМЕЧАНИЯ

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.
