Color Mineral Map of Cuprite Nevada Researchers at the USGS Spectroscopy Lab are studying and applying methods for identifying and mapping materials through spectroscopic remote sensing (called imaging spectroscopy, hyperspectral imaging, imaging spectrometry, ultraspectral imaging, etc), on the earth and throughout the solar system using laboratory, field, airborne and spacecraft spectrometers.

The image shown here is a mineral map, where each color is the identification of specific minerals through imaging spectroscopy analysis. See Material Maps and Spectral Libraries (also accessed below).

Library Icon USGS Digital Spectral Libraries

Reflectance spectra of minerals, mineral mixtures, rock coatings, liquids, frozen volatiles, organic compounds, manmade materials, vegetation, and other biological materials.

You can download the main spectral library or versions convolved to various remote sensing spectrometers and broad band imagers.

Also, you can view spectra online.
SPECTRAL LIBRARY, splib07a, is now online . Real Hot
