Abstract
In this study, two MODTRAN-based software packages (FLAASH and ATCOR-4) were employed to conduct atmospheric correction on a hyperspectral dataset, collected by a Itres CASI-1500 in Southern Taiwan with a spectral range of 367 - 1047 nm and a spectral resolution of 9.6 nm. ATCOR-4 is capable of including topographic effect (such as slope and aspect) in atmospheric correction when a DEM or DSM is provided. The effect of topographic factor was demonstrated by comparing the results obtained from FLAASH and ATCOR-4 with in-situ measurements, using a PSR-1100 spectroradiometer, respectively. The preliminary results showed that ATCOR-4 produced the best result when a smoothed DSM is provided. However the processing time for obtaining such result in significantly longer than FLAASH.
