wxGUI GCP Manager for photo to image registration


       This  module  is  based  on  g.gui.gcp,  the  GCP  manager  of  GRASS  GIS.  It is part of 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 (,  a  camera
       description   file  (  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 Location imagery60:
       g.gui.photo2image group=aerial@PERMANENT raster=gs13.1@PERMANENT camera=gscamera order=2 extension=try --o
