AbstractThe study presented in this paper investigated the influence of radiative transfer (RT) codes upon the surface reflectance retrieval and, ultimately, upon the spectral unmixing for mineral identification and mapping of mineral abundances. The effect of post-processing of the RT code retrieved surface reflectance was also studied. For this purpose, an AVIRIS radiance cube acquired over the Cuprite mining district area in Nevada on June 12, 1996 was used to generate the surface reflectance using the three RT codes ATREM (ATmospheric REMoval program), CAM5S (Canadian Advanced Modified 5S), and MODTRAN4 (MODerate atmospheric radiance and TRANsmittance model). The mineral abundance maps generated from MODTRAN4 reflectance data showed the best match with a classification carried out by the United States Geological Survey [USGS 98]. However, the resulting fraction maps produced based on ATREM and CAM5S reflectance data are quite similar for most minerals identified, with the exception of montmorillonite and chalcedony. In addition, differences occur in several cases between the RT code retrieved reflectance and post-processed data.
