USGS Digital Spectral Library 06

Researchers at the Spectroscopy Lab have measured the spectral reflectance of hundreds of materials in the lab, and have compiled a spectral library. The library is used as a reference for material identification in remote sensing images. This web page provides links to the splib06* series of spectral library data and supporting information.

The following links to the Data Series 231 report and includes the description of how spectra were measured, sample purity, full sample descriptions, plots of the spectra, and ASCII listings of all data.

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 following URL links to the digital data, including native spectrometer data, interpolated spectra, and convolved instrument spectral libraries. These data are dynamic and new interpolations and convolutions are computed as flight instruments change. As new information on sample purity becomes available, the sample documentation will be dynamically updated.
