I have a worldview 3 image (Level 1B product with 17 bands, 1 Pan, 8 MS, and 8 SWIR). I need to apply an atmospheric correction to the image. After I apply radiometric calibration with ENVI 5.4, SWIR bands result in no data pixels in some areas covered with water. This happens with both FLAASH settings and default settings in radiometric calibration. As I understand, only option I have with ENVI is I can apply QUAC for the original image. Then apply (B1 le 0)*0+(B1 ge 10000)*1+(B1 gt 0 and B1 lt 10000)*float (b1)/10000 equation to scale the data to 0 to 1 range.
Can anyone help me to find a better method to use radiometric calibration and FLAASH or QUAC to correct my image to BOA level?
Thank you in advance..!
Afjal, You can go to ENVI forum and there is a descriptive answer for this question.
