47 r.basins.fill generates a raster map layer depicting subbasins, based
48 on input raster map layers for the coded stream network (where each
49 channel segment has been "coded" with a unique category value) and for
50 the ridges within a given watershed. The raster map layer depicting
51 ridges should include the ridge which defines the perimeter of the
52 watershed. The coded stream network can be generated as part of the
53 r.watershed program, but the map layer of ridges will need to be cre‐
54 ated by hand (for example, through digitizing done in wxGUI vector dig‐
55 itizer).
56
57 The resulting output raster map layer will code the subbasins with cat‐
58 egory values matching those of the channel segments passing through
59 them. A user-supplied number of passes through the data is made in an
60 attempt to fill in these subbasins. If the resulting map layer from
61 this program appears to have holes within a subbasin, the program
62 should be rerun with a higher number of passes.
63
65 The current geographic region setting is ignored. Instead, the geo‐
66 graphic region for the entire input stream’s map layer is used.
