Abstract
Documentation of hyperspectral data of selected rocks and minerals and validation of the measured spectral values with ASTER data are presented in this chapter. Spectral data were generated by using the instrument SVC HR 1024 Spectroradiometer with a wavelength range of 350–2,500 nm. The spectra were compared with USGS and JHU spectral library. Advanced Space-borne Thermal Emission and Reflection Radiometer (ASTER) data acquired in the Visible Near Infra Red (VNIR) and Short Wave Infra Red (SWIR) regions were used to evaluate the spectral discrimination of rocks and minerals. The SAM technique was used to detect the presence of minerals (e.g. Magnesite and Bauxite) in the study area and then the spectral library was validated with the SAM results.
