{{{
r.stream.extract elevation=elevation@PERMANENT threshold=100
stream_raster=rstream
Performs stream network extraction.
Usage:
r.stream.extract elevation=name [accumulation=name]
[depression=name]
threshold=value [d8cut=value] [mexp=value]
[stream_length=value]
[memory=value] [stream_raster=name] [stream_vector=name]
[direction=name] [--overwrite] [--help] [--verbose]
[--quiet] [--ui]
Flags:
Parameters:
elevation Name of input elevation raster map
accumulation Name of input accumulation raster map
depression Name of input raster map with real
depressions
threshold Minimum flow accumulation for streams
d8cut Use SFD above this threshold
default: infinity
mexp Montgomery exponent for slope, disabled
with 0
default: 0
stream_length Delete stream segments shorter than
stream_length cells
default: 0
memory Maximum memory to be used (in MB)
default: 300
stream_raster Name for output raster map with unique
stream ids
stream_vector Name for output vector map with unique
stream ids
direction Name for output raster map with flow
direction
ERROR: Missing value for parameter <d8cut>
