DESCRIPTION
i.group allows the user to collect raster map layers in an imagery
group by assigning them to user-named subgroups or other groups. This
enables the user to run analyses on any combination of the raster map
layers in a group. The user creates the groups and subgroups and se-
lects the raster map layers that are to reside in them. Imagery analy-
sis programs like g.gui.gcp, i.rectify, i.ortho.photo and others ask
the user for the name of an imagery group whose data are to be ana-
lyzed. Imagery analysis programs like i.cluster and i.maxlik ask the
user for the imagery group and imagery subgroup whose data are to be
analyzed.
NOTES
The i.group options are only available for imagery map layers in the
current LOCATION_NAME.
Subgroup names may not contain more than 12 characters.
EXAMPLE
This example runs in the "landsat" mapset of the North Carolina sample
dataset. The following command creates a group and subgroup containing
only the visible light bands of Landsat-7:
i.group group=vis_bands subgroup=vis_bands input=lsat7_2000_10,lsat7_2000_20,lsat7_2000_30
