USGS Spectroscopy Lab
Researchers at the USGS Spectroscopy Lab are studying and applying methods for
identifying and mapping materials through spectroscopic remote sensing
(called imaging spectroscopy,
ultraspectral imaging, etc), on the
earth and throughout the solar system using
field, airborne and
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).
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
Also, you can view spectra online.
SPECTRAL LIBRARY, splib07a, is now online
(see dates below for additions).
Spectroscopy and Imaging Spectroscopy
Extensive tutorial on reflectance spectroscopy, the causes of absorption bands,
the absorption and scattering processes that occur when light
encounters a particulate surface, and principles of spectroscopy including continuum
analysis, grain size effects, mixtures, etc.
The detailed description of the imaging spectroscopy mapping system we for most maps
you see on speclab.
A tutorial on what imaging spectroscopy is, what it can be used for, and what
it takes to plan, request, calibrate, and analyze AVIRIS data.
Tutorials and papers with image examples of what can be done with imaging
spectroscopy. Maps of minerals, vegetation (including species),
environmental hazards, and more.
