45 i.group allows the user to collect raster map layers in an imagery
46 group by assigning them to user-named subgroups or other groups. This
47 enables the user to run analyses on any combination of the raster map
48 layers in a group. The user creates the groups and subgroups and
49 selects the raster map layers that are to reside in them. Imagery anal‐
50 ysis programs like i.points, i.rectify, i.ortho.rectify and others ask
51 the user for the name of an imagery group whose data are to be ana‐
52 lyzed. Imagery analysis programs like i.cluster and i.maxlik ask the
53 user for the imagery group and imagery subgroup whose data are to be
54 analyzed.
55
57 The i.group options are only available for imagery map layers in the
58 current LOCATION_NAME.

60 Subgroup names may not contain more than 12 characters.
