Hi All,

I have been working on 16 band Worldview-3 image for alteration mapping of my project area.
I am using ENVI 5.5.2 and the workflow that I follow for the preprocessing s:

>File>Open As>Optical Sensors>WOrldview-3 (Multispectral and SWIR bands are imported and saved seperately)
>Wavelengths of SWR bands are corrected manually from "Edit Metadata" since they are they are imported as micrometer.
>Layer stacking for MS and SWR bands
>Radiometric Calibration
>FLAASH Atmospheric correction.

After applying these steps I checked the spectral profiles of some random points and alteration area and realised that there is an absorption in 950 nm in most of the pxels. Since this point is the transition wavelength between MS and SWR bands, I am a bit worried about if I did something wrong with the calibration of the bands.
I also checked the spectral library of worldview-3 and didn't see that there is a common absorption in this wavelength.

Does anybody realised this kind of problem in processing of Worldview-3 images?

Kind Regards
