Hi all, I'm having difficulties getting meaningful outputs from FLAASH for WorldView2 data. I have performed radiometric correction using the gain & offset values from the image header file and radiometric calibration to radiance (getting an output file with values in the order of 0.00X). When I run this image through FLAASH, specifying tropical atmospheric model and rural aerosol model, selecting NO for water and aerosol retrieval, I get an output image with negative values of several hundred when I would expect an output in the range 0-100. Any suggestions as to what is going wrong here?
