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 selects the raster map layers that are
       to reside in them. Imagery analysis programs like i.points, i.rectify, i.ortho.photo 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.

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.
