DESCRIPTION

56       i.group allows the user to collect raster  map  layers  in  an  imagery
57       group  by  assigning them to user-named subgroups or other groups. This
58       enables the user to run analyses on any combination of the  raster  map
59       layers  in  a  group.   The  user  creates the groups and subgroups and
60       selects the raster map layers that are to reside in them. Imagery anal‐
61       ysis  programs  like g.gui.gcp, i.rectify, i.ortho.photo and others ask
62       the user for the name of an imagery group whose data  are  to  be  ana‐
63       lyzed.  Imagery  analysis  programs like i.cluster and i.maxlik ask the
64       user for the imagery group and imagery subgroup whose data  are  to  be
65       analyzed.
66

NOTES

68       The  i.group  options  are only available for imagery map layers in the
69       current LOCATION_NAME.
70
71       Subgroup names may not contain more than 12 characters.
72
73   EXAMPLE
74       This example runs in the "landsat" mapset of the North Carolina  sample
75       dataset.  The following command creates a group and subgroup containing
76       only the visible light bands of Landsat-7:
77       i.group group=vis_bands subgroup=vis_bands input=lsat7_2000_10,lsat7_2000_20,lsat7_2000_30
