change_4 Documentation

change_4 - Convert a qmatch list of Clem. pixel measurements to mm
change_4 creates a geodesy (RAND) measurement file from a qmatch
match point file and a list of cube files that contain all the match
points.  The MATFROM match point file contains the points from which
to generate a geodesy measurement file. The program is to be used
with Galileo measurements.

The format of the output file is as follows:

image_number fl point_id x  y

where image_number is the full frame image number,
fl is focal length in mm, point_id is an ascii point identifier,
x and y are the point positions in the full frame in mm.

ADDITIONAL NOTES:

Parm	Description
MATFROM	Input match file name. Contains the list of measured sample/line positions. It has fields containing a point id, image number, line and sample coordinate and point class, sub-pixel correlation and, diameter of measured feature. Only image number and pixel position are used in this application.
RANDTO	Output match file name. This file will be generated from the contents of the MATFROM file. The file will contain a list of the same points as the input file with the following required fields: full frame image number, focal length of the imaging instrument, point id, position of point in full frame in mm (x and y).
