       This module is based on g.gui.gcp, the GCP manager of GRASS GIS.  It is part of i.ortho.photo suite.

       The aim of this module is to give absolute location values to the fiducial points present (in number of 4
       or 8) in a scanned aerial photo.

       This  is  necessary as (manual) scanning introduces distortions, rotations and also may not be limited to
       scan the boundary of the photo itself.  It  is  thus  necessary  to  give  to  each  fiducial  the  exact
       coordinates in mm as given by the aerial photographic instrument design, which is unique per camera.

       This module requires you to have made a group with your aerial photo (i.group), a camera description file
       (i.ortho.target)  and  use  them  to  launch  the  module.  Additional  requirements  are  the  order  of
       rectification (1 if no of Fiducials is 4, 2 if no of Fiducials is 8) and an extension file (if not given,
       defaults to \$filename_ip2i_out)

       An example for project imagery60:
       g.gui.photo2image group=aerial@PERMANENT raster=gs13.1@PERMANENT camera=gscamera order=2 extension=try --o
