USGS Digital splib04 Spectral Library

Sample Descriptions and Plots

This page enables access to the sample description pages for the spectral library along with customized plots. The plots will include pointers to causes of absorption features (in blue) and any contaminant spectral features in red. It is a big job to edit all the plot images so this will be an ongoing project as we have time. The table will ultimately be expanded to the left with plots at longer wavelengths as we bring the mid-far infrared spectral libraries online. We intend to have 3 plots: 0.2-3.0 microns, 1.5 to 6 microns, and 5 to 150 microns (plot in wavenumbers).
