DESCRIPTION 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 selects the raster map layers that are to reside in them. Imagery analysis programs like g.gui.gcp, i.rectify, and others ask the user for the name of an imagery group whose data are to be analyzed. 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.


The options are only available for imagery map layers in the current LOCATION_NAME.

Subgroup names may not contain more than 12 characters.


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: group=vis_bands subgroup=vis_bands input=lsat7_2000_10,lsat7_2000_20,lsat7_2000_30
