USGS Digital Spectral Library
Researchers at the Spectroscopy Lab have measured the spectral
reflectance of hundreds of materials in the lab, and have compiled a
spectral library. The libraries are used as references for
material identification in remote sensing images.
Older Spectral Libraries
Spectral library splib04a is:
Spectral Library splib04a Sample Descriptions
along with detailed plots.
January 8, 2000.
(For your information, libraries 01, 02, and 03 were experimental
exercises on what to include in a spectral library.)
The splib07a spectral library is currently being prepared. Included
in the new library will be an extensive grain size series for many minerals,
more organic and volatile compounds, more minerals and other
materials. Publication date depends on funding.

Our Current Spectral Library, splib06a (September, 2007):
Clark, R.N., Swayze, G.A., Wise, R., Livo, E., Hoefen, T., Kokaly, R., Sutley, S.J.,
2007, USGS digital spectral library splib06a: U.S. Geological Survey, Digital Data
Series 231.
The UV to mid-infrared 0.2-150 micron library (splib06) contains
over 1300 spectra including mid-infrared data as well as spectra from
splib05a and additional visible and near-infrared spectra. The library
includes many more minerals, organic and volatile compounds, vegetation,
and man-made materials than our previous libraries.
The database is over 6,000 web pages, figures, sample images and data listings.

library, description, plots of spectra, and ascii data. Binary
