Paper Abstract

Using remote sensing data for geological applications requires specific spatial and spectral resolution combinations for the different geological problems. We evaluate the most adequate combinations for (1) lithological analysis and (2) delineation of depositional bodies. Responses of various hyperspectral and multispectral sensors were simulated using 2000 - 2500 nm laboratory reflectance spectra of metamorphic rocks. MIVIS data (40 bands in the 2000 - 2500 nm region) of a littoral were resampled and used to produce images with various band width and centers and with different ground resolutions. All the images were classified using Spectral Angle Mapper. Heat capacity images of a recent delta plain were obtained using spatially resampled MIVIS data and checking various combinations of resolutions for coalbedo and temperature increment.
