DESCRIPTION

54       This module is based on g.gui.gcp, the GCP manager of GRASS GIS.  It is
55       part of i.ortho.photo suite.
56
57       The aim of this module is to give absolute location values to the fidu‐
58       cial points present (in number of 4 or 8) in a scanned aerial photo.
59
60       This is necessary as (manual) scanning  introduces  distortions,  rota‐
61       tions  and  also  may  not be limited to scan the boundary of the photo
62       itself. It is thus necessary to give to each fiducial the exact coordi‐
63       nates  in  mm  as  given  by the aerial photographic instrument design,
64       which is unique per camera.
65
66       This module requires you to have made a group with  your  aerial  photo
67       (i.group),  a  camera description file (i.ortho.target) and use them to
68       launch the module. Additional requirements are the order of  rectifica‐
69       tion  (1  if  no  of  Fiducials is 4, 2 if no of Fiducials is 8) and an
70       extension file (if not given, defaults to \$filename_ip2i_out)
