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.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.
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.
