r.slopeunits.metrics

Create metrics for slope units

r.slopeunits.metrics basin=name demmap=name slumapclean=name cleansize=float areamin=float cvmin=float resolution=float [outfile=name] [--overwrite] [--verbose] [--quiet] [--qq] [--ui]

Example:

r.slopeunits.metrics basin=name demmap=name slumapclean=name cleansize=25000 areamin=float cvmin=float resolution=float

grass.script.run_command("r.slopeunits.metrics", basin, demmap, slumapclean, cleansize=25000, areamin, cvmin, resolution, outfile=None, overwrite=False, verbose=False, quiet=False, superquiet=False)

Example:

gs.run_command("r.slopeunits.metrics", basin="name", demmap="name", slumapclean="name", cleansize=25000, areamin=float, cvmin=float, resolution=float)

DESCRIPTION

r.slopeunits.metrics creates metrics for slope units. Returns output "areamin, cvmin, v_fin and i_fin" to stdout, optionally writes to a file.
