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.
