Dear all, I tried to make the atmospheric correction with FLAASH but I had some problems with "input radiance image". I used SeaDAS to get the L2 product (calibrated TOA radiance) of MERIS, saved 14 bands of calibrated TOA radiance as ENVI standard format and converted it to BIL format. When I clicked "input radiance image" and selected the converted image, it said error: "READF: input conversion error. Unit 100, File: F:\image\stack_radiance_erie_bil" The result may be invalid. If someone knows how to solve it? Thanks, Jie
