Abstract: A calibration method has been applied on satellite data in the visible infrared spectral range from which spectral reflectance and emissivity may be retrieved. This dissertation describes the steps needed for multispectral/hyperspectral data calibration and a number of algorithms for reflectance and emissivity retrieval. The methodology is applied to retrieve reflectance and emissivity of volcano Teide and is validated through a comparison with “ground truth”. The “ground truth” spectra have been acquired during a field campaign carried on September 2007. As application of calibrated-validated data, the classification of the volcano Teide and the temperature map are discussed.
