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 se‐
60 lects the raster map layers that are to reside in them. Imagery analy‐
61 sis 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
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.

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
