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.
Ftp binary and ascii data for splib05a from:

(For your information, libraries 01, 02, and 03 were experimental
excersizes on what to include in a spectral library.)
The mid-infrared 1.5-150 micron library (splib06) contains about 400 samples
of mid-infrared data as well as spectra from splib05a and additional visible
and near-infrared spectra will be released as soon as
complete. When ths library will be complete depends on manpower
assigned to work on this task. Target: end of 2004.

Splib05a contains 800+ spectra of minerals, mixtures, artificial, liquids and
volattiles and vegetation, each with documentation.

library, description, plots of spectra, and ascii data. Binary
files and instrument convolved spectral libraries will be posted
on the speclab site soon.
