tiept - Correct camera pointing using image correlation
TIEPT will calculate and record in the label of the FROM file up to 9
tie point values for 2 overlapping images.  For each tie point the
following information will be stored in the label of the first image:
(1) a tie point number, (2) lat,lon position calculated from the
second image, and (3) the sample and line coordinates for the same point
on the first image.  The camera angles will also be updated on the first
image.

NOTE: The images being registered with TIEPT must also be geomed with
the same lat,lon range or the subpixel registration will be lost.

Programmer:  Kay Edwards, U.S.G.S., Flagstaff, AZ

ADDITIONAL NOTES:

ParmDescription
FROM
Input cube file name.  If the file extension is omitted,
then ".cub" will be assumed.
FROM2
Second input cube file name.  If blank, use a band from the
first input cube.  This image will be used as "truth" to
correct camera pointing on image 1.
BAND
Specifies the core band to be used to pick the tie points
for the first and second images.
TOL
Enter the tolerance factor for calculating the sample and
line locations of the tie points.
MINPT
The user may select the minimum number of valid points to be
used to update the camera angles.  If less than the minimum
number of points are found, the camera angles will not be
updated and the program will exit with a warning.
USERNOTE
Specifies a comment that will be entered into the output
log file and history entry in the output file.
