Title: Geological classification of Volcano Teide by hyperspectral and multispectral satellite data
Issue Date: 2013

Abstract: Tenerife is the central island of the Canary Archipelago (Spain), which consists of seven islands that represent different stages of geological evolution. The Teide-Pico Viejo (28◦ 16 30 N, 16◦ 38 42 W) stratocones formed during the last eruptive phase of the isle of Tenerife. It is an active, though currently quiescent, shield volcano that last erupted in 1909 and is located on the Tenerife Island. In the framework of the European Project FP6 Prevention, Information and EarlyWarning (PREVIEW)-EURORISK (http://www., a field campaign was performed on Tenerife Island on September 2007. This campaign focused on the acquisition of in situ reflectance and emissivity spectra relative to Pico de Teide and Las Cañadas Caldera. The collected spectra represented the ‘ground truth’ and have been used for the supervised classification on multispectral (Advanced Spaceborne Thermal Emission and Reflection Radiometer (ASTER)) and hyperspectral (Earth Observing 1 (EO1)-Hyperion) data. The first ever classification mapping carried out on the Teide Volcano by utilizing the remote-sensing method is reported in this article. The methods used to process and to classify the data are discussed, and a comparison with the existing geological maps is presented
