- 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

- 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.
