       group=name
           Name of imagery group

       subgroup=string

       input=name[,name,...]
           Name of raster map(s) to include in group

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.
