Abstract
The Spatially Enhanced Broadband Array Spectrograph System (SEBASS) is one of the few systems that acquire hyperspectral data sets in the thermal infrared (TIR). Many rock forming minerals display distinct spectral features mainly (or exclusively) in the 8-12μm range (“Reststrahlen bands”). Hence, development of good TIR instruments and algorithms are of high importance for geologic remote sensing. With 128 contiguous bands each in the 2.5-5.2μm as well as in the 7.5-13.5μm wavelength range, SEBASS has great potential for geologic mapping and mineralogic mapping. We investigate SEBASS data acquired in September 1999 over an area near Yerington, Nevada (USA). Preprocessing of SEBASS involves an in-scene atmospheric correction, noise removal/data reduction, as well as an emissivity/temperature separation. However, band-to-band noise and residual atmospheric features still remain in the dataset and make interpretations difficult for wavelengths <8.5μm and >11μm.
