Imaging spectrometers or {open_quotes}Hyperspectral Sensors{close_quotes} simultaneously collect spectral data as both images and as individual spectra. A broad range of techniques have been examined, refined, and put into operational practice for analysis of geologic problems. This paper describes a successful geologic case history using an end-to-end approach on Airborne Visible/Infrared Imaging Spectrometer (AVIRIS) data, including data calibration to reflectance, use of a linear transformation to minimize noise and determine data dimensionality, location of the most spectrally pure pixels, extraction of end member spectra, and spatial mapping of specific end members. Several supporting case studies using AVIRIS data of near-shore marine environments demonstrate the viability of these methods for studying the coastal zone. The methods described provide a starting point for image segmentation, material identification, and mapping of marine processes in the near-shore environment.
