Title: Geological classification of volcano Teide by hyperspectral and multispectral satellite data, Recent Advances in Quantitative Remote Sensing
Issue Date: 27-Sep-2001
Keywords: Classification

Abstract: The Canarian Arcipelago is made up of seven islands that represent different stages of geologic evolution. Tenerife is the central island of archipelago and has developed within the complex formed by the rifts associated with the Teide-Pico Viejo (T-PV-Lat 28° 16’ 30” Lon 16°38’ 42”) stratovolcanoes that reach a height of 3718m, 7500 above the ocean floor. It is an active, though currently quiescent shield volcano, which last erupted in 1909. In this study we have geologically characterized Volcano Teide by using multispectral and hyperspectral satellite imaging data. Radiance data were preprocessed and calibrated into reflectance, following which unsupervised and supervised classification methods were applied. The supervised classification primarily utilized in situ ground truth obtained during 2007 field campaign (EC project PREVIEW FP6). In this work we compare results obtained by using several methods.
