Flags:
- -a
- Set for 8 cell-neighbors. 4 cell-neighbors are default
- --help
- Print usage summary
- --verbose
- Verbose module output
- --quiet
- Quiet module output
- --ui
- Force launching GUI dialog
Parameters:
- input1=name
- Name of input raster map
- output=string [required]
- Name for output ASCII-file (use out=- for stdout)
- keyval=integer
- Value of a category from the input file to measure desired landcover
- nullval=integer[,integer,...]
- Values marking areas from the input file, which are to be NULL in the resulting map
- landcover=float
- Landcover in percent
- sharpness=float
- Small values produce smooth structures, great values produce sharp, edgy structures - Range [0-1]
