Greetings,
I imported an EO-1 Hyperion L1T MTL image cube into ENVI using Hyperion Tools and checked all three options (Output ENVI Mask Image, Convert BSQ to BIP Interleave, Output FLAASH Scale Factors). I then attempted atmospheric correction using FLAASH while trying to follow the EO-1 User Guide (Beck, 2003,
http://edcsns17.cr.usgs.g...v2pt320030715UC.pdf) using the directions for FLAASH.
The only deviation from manual is that I did not input the IFOV as I could not find this in the Advanced Settings or anywhere else (I am guessing this was avaiable only on an earlier version of ENVI/FLAASH).
Upon clicking "Apply" I soon received the following ENVI error message:
Problem: The FLAASH Program exited with the following errors:
ACC Error: avrd: No nonblank pixels found
IDL error:
