SYNOPSIS
v.stream.inbasin
v.stream.inbasin --help
v.stream.inbasin [-s] input_streams=name [input_basins=name] [draindir=name] [cat=string] [coordinates=east,north] [output_basin=name] [output_streams=name] [output_pour_point=name] [--overwrite] [--help] [--verbose] [--quiet] [--ui]
Flags:
- -s
- Snap provided coordinates to nearest segment endpoint
- --overwrite
- Allow output files to overwrite existing files
- --help
- Print usage summary
- --verbose
- Verbose module output
- --quiet
- Quiet module output
- --ui
- Force launching GUI dialog
Parameters:
- input_streams=name [required]
- Stream network
- Or data source for direct OGR access
- input_basins=name
- Subbasins built alongside stream network
- Or data source for direct OGR access
- draindir=name
- Drainage directions (needed if exact coordinates used)
- Name of input raster map
- cat=string
- Farthest downstream segment category
- coordinates=east,north
- Pour point coordinates
- The alogorithm will find the closest stream segment
- output_basin=name
- Vector output drainage basin
- Name for output vector map
- output_streams=name
- Streams within vector output drainage basin
- Name for output vector map
- output_pour_point=name
- Basin outlet
- Name for output vector map
v.stream.inbasin uses the output of
v.stream.network to
select only those streams (and sub-basins) that are upstream of (and inclusive
of) a selected link in the network. It is used as a step to develop GSFLOW
model inputs for a watershed, but need not be exclusively used for that
purpose.
v.stream.inbasin expects the stream network attributes created by
v.stream.network and named using the names
v.stream.network
uses by default. In other words,
v.stream.inbasin will work on the
output
v.stream.network with default attribute names.
