Evaluation of casi and SFSI Hyperspectral Data for Environmental and Geological Applications - Two Case Studies

RESUMELe potentiel de deux spectrometres imageurs, le Compact Airborne Spectrographic Imager (casi) et le SWIR (Short-Wave Infra-Red) Full Spectrum Imager (SFSI), a ete evalue dans le contexte d'applications en environnement et en geologie. On presente les resultats de deux etudes de cas, l'une visant l'identification des mineraux a Cuprite, au Nevada, et l'autre consistant en une caracterisation environnementale d'un site minier et de sa rehabilitation, pres de Sudbury, en Ontario. Des donnees SFSI SWIR II (2000 nm-2400 nm) ont ete utilisees dans le cas de la cartographie mineralogique alors que les donnees casi dans le visible et le proche infrarouge (VNIR) (450 nm-900 nm) ont ete appliquees dans le cas de l'etude environnementale. Le processus d'evaluation comprenait l'extraction des reflectances de surface prealablement a l'application du demixage spectral pour l'identification de materiaux specifiques, et la validation subsequente de l'information extraite. Les resultats ont demontre que l'on pouvait...
