DESCRIPTION

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.
