Discrimination of Geological End Members Using Hyperion Imagery: Preliminary Results, Big Bend National Park, Texas

Hyperion hyperspectral data are being tested as a means for generating databases of surface cover at Big Bend National Park, Texas. Preliminary unmixing results indicate a capacity for discrimination of general geological classes, but separation of several sedimentary end members has proven difficult due to shared weathering characteristics. Of special interest in this study is the utility of hyperspectral data in the mapping of fractional lithological compositions of widespread alluvial deposits.
