DESCRIPTION

33       i.group allows the user to collect raster  map  layers  in  an  imagery
34       group  by  assigning them to user-named subgroups or other groups. This
35       enables the user to run analyses on any combination of the  raster  map
36       layers  in  a  group.   The  user  creates the groups and subgroups and
37       selects the raster map layers that are to reside in them. Imagery anal‐
38       ysis  programs like i.points, i.rectify, i.ortho.rectify and others ask
39       the user for the name of an imagery group whose data  are  to  be  ana‐
40       lyzed.  Imagery  analysis  programs like i.cluster and i.maxlik ask the
41       user for the imagery group and imagery subgroup whose data  are  to  be
42       analyzed.
