DESCRIPTION
r.basins.fill generates a raster map layer depicting subbasins, based
on input raster map layers for the coded stream network (where each
channel segment has been "coded" with a unique category value) and for
the ridges within a given watershed. The raster map layer depicting
ridges should include the ridge which defines the perimeter of the wa-
tershed. The coded stream network can be generated as part of the
r.watershed program, but the map layer of ridges will need to be cre-
ated by hand (for example, through digitizing done in wxGUI vector dig-
itizer).
The resulting output raster map layer will code the subbasins with cat-
egory values matching those of the channel segments passing through
them. A user-supplied number of passes through the data is made in an
attempt to fill in these subbasins. If the resulting map layer from
this program appears to have holes within a subbasin, the program
should be rerun with a higher number of passes.
NOTES
The current geographic region setting is ignored. Instead, the geo-
graphic region for the entire input stream’s map layer is used.
