r.pi.grow

Size and suitability based region growing.

Command linePython (grass.script)

r.pi.grow [-a] input=name [costmap=string] output=name keyval=integer area=integer method=string [seed=integer] [--overwrite] [--verbose] [--quiet] [--qq] [--ui]

Example:

r.pi.grow input=name output=name keyval=integer area=integer method=string

grass.script.run_command("r.pi.grow", input, costmap=None, output, keyval, area, method, seed=None, flags=None, overwrite=False, verbose=False, quiet=False, superquiet=False)

Example:

gs.run_command("r.pi.grow", input="name", output="name", keyval=integer, area=integer, method="string")
