We have assembled a digital reflectance spectral library of over 800 spectra that covers the ultraviolet to near-infrared region of the electromagnetic spectrum along with sample documentation. The library includes samples of minerals, rocks, soils, physically constructed as well as mathematically computed mixtures, vegetation, microorganisms, and man-made materials. The samples and spectra collected were assembled for the purpose of using spectral features for the remote detection of these and similar materials.
Analysis of spectroscopic data from the laboratory, aircraft, and spacecraft requires a knowledge base. The spectral library discussed here forms a knowledge base for the spectroscopic identification of minerals and related materials important to a variety of research programs being conducted on the Earth and other planets. Imaging spectrometers, such as the Airborne Visible/Infra-Red Imaging Spectrometer (AVIRIS), or the Cassini Visual and Infrared Mapping Spectrometer (VIMS) on its way to orbit Saturn in 2004, have narrow band widths in many contiguous spectral channels that permit accurate definition of absorption features from a variety of materials. Identification of materials requires a comprehensive spectral library of minerals, vegetation, man-made materials, and other subjects in the scene. This new database includes minerals found in hydrothermal alteration zones and weathering products that may be important in the exploration of Mars. This library includes all spectra used in the Clark et al, (JGR in Press 2003) Tetracorder imaging spectroscopy mapping system. Chapters of the library are:
Chapter 1: M = Minerals, Chapter 2: S = Soils, Rocks, Mixtures, Chapter 3: C = Coatings, Chapter 4: L = Liquids, Liquid Mixtures, Water and Other Volatiles Including Frozen Volatiles, Chapter 5: A = Artificial (Man-Made) Including Manufactured Chemicals, Chapter 6: V = Vegetation, Mixtures with Vegetation, and Micro-Organisms.
