.SH DESCRIPTION
This module is based on \fBg.gui.gcp\fR, the GCP manager of GRASS GIS.
It is part of i.ortho.photo suite.
.PP
The aim of this module is to give absolute location values to the fiducial
points present (in number of 4 or 8) in a \fIscanned\fR aerial photo.
.PP
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.
.PP
This module requires you to have made a group with your aerial photo \fB(i.group)\fR, a camera
description file \fB(i.ortho.target)\fR 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 \(rs$filename_ip2i_out)
