Hyperspectral Signatures (400 to 2500 nm) of Vegetation, Minerals, Soils, Rocks,and Cultural Features: Laboratory and Field Measurements

摘要

The objective of this catalog was to document the visible near-infraredreflectance spectra (400-2500nm) of vegetation, soils, rocks, and man-made materials, and to provide information about their unique physical and chemical properties. Spectra were taken of representative samples of a particular plant species or soil type and selected conditions so that a specific feature could be evaluated. Seasonal differences in vegetation spectra were measured for tree, shrub, herbaceous, and grass species. Soils having different textures and moisture potentials were measured. These spectra summarize results of ongoiung research in different environments, although many of the field spectra were taken in semiarid and arid environments.
