    Hello Folks, Can we apply 'Zenith and Azimuth' angles for Landsat 8 OLI in 'Flaash Advanced Settings'? In landsat8 OLI .MTL file, following data are given: ROLL_ANGLE = -0.001 SUN_AZIMUTH = 103.56111968 SUN_ELEVATION = 69.25538672

    Those values are the Sun elevation and azimuth. They are used in calibration but FLAASH uses the sensor zenith and azimuth. I have not seen many off-nadir Landsat scenes. What does it show in the metadata for this setting? NADIR_OFFNADIR = "NADIR" If it is NADIR, you do not need to use these settings in FLAASH.
