Hello all, I am attempting to convert raw DN values of an IKONOS image from 2008 into radiance values (W m-2 sr-1 um-1). I'm assuming I can use spectral math with the conversion coefficients, but I'm just not sure which coefficients to use. There seem to be several values listed rather vaguely in the literature. Has anyone done this recently that could direct me on the right path? Thank-you in advance for your time, Jenn
