r.li.mpa
(mean pixel attribute) calculates the average value of the attribute of all the non-null
cells in the sampling area as:
with:
i: attribute
m: number of non-null attributes in the sampling area
wi: number of cells of attribute i
size: size of sampling area (in cells)
EXAMPLES
To calculate mean pixel attribute index on map my_map, using
my_conf configuration file and saving results in
my_out file run:
r.li.mpa map=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 full of null values r.li.mpa consider to
have 0 patch.
If area is 0 r.li.mpa returns -1; it is possible only if the
raster is masked
If you want to have null values instead run
