I'm working with a push-broom style hyperspectral imager that outputs separate coordinate and aircraft yaw/pitch/roll information for each row (frame) of the generated image. That information is contained in a separate "Navigation" text file. The header file (below) which accompanies the image does not provide any coordinate information.
Can anyone give me any general tips on how to pass the row coordinates, and yaw/pitch/roll information to ENVI so I can get the image to display correctly? I have pasted the contents of an example header file, followed by a single frame from the accompanying Navigation data file below.
If it can't readily be done, I'd like to know. If it will require some advanced programming skills, that would be helpful too. I'm fairly new to ENVI still.
==============================
Header file contents:
ENVI

data type = 12
lines = 10000
samples = 680
bands = 60
interleave = bip
byte order = 0
wavelength units = Nanometers
wavelength = {401.67, ...}
