DESCRIPTION

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

NOTES

65       The  current  geographic  region setting is ignored.  Instead, the geo‐
66       graphic region for the entire input stream’s map layer is used.
