Description:

Researchers at the USGS Spectroscopy Lab are studying and applying methods for identifying and mapping materials through spectroscopic remote sensing (called imaging spectroscopy, hyperspectral imaging,imaging spectrometry, ultraspectral imaging, etc), on the earth and throughout the solar system using laboratory, field, airborne and spacecraft spectrometers.USGS Digital Spectral LibrariesReflectance 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 librarySpectral LibraryHyperspectral Imaging Spectrometer MapsMaps of hyperspectral imaging spectrometer data used to identify and characterize mineral deposits, vegetation, and other land surface features.Hyperspectral Maps The USGS Spectroscopy Laboratory hosted hyperspectral calibration and imaging from unmanned aircraft systems (UAS) training in June. U.S. Geological Survey scientists and partners have created an onsite, time-saving technique for building inspectors to ascertain whether vermiculite insulation contains amphibole asbestos. The findings are featured in the April 2 edition of American Mineralogist. Year Published: 2020 Quantifying uncertainty for remote spectroscopy of surface composition Remote surface measurements by imaging spectrometers play an important role in planetary and Earth science.To make these measurements, investigators calibrate instrument data to absolute units, invert physical models toestimate atmospheric effects, and then determine surface properties from the spectral reflectance. This studyquantifies the...

Identification of these particles and their effects are relevant to snow-radiation modeling and thus water-resource management. Laboratory-measured reflectance of DOS samples from the San Juan...

Satellite SAR has primarily been used to detect the presence/absence of oil, yet its ability to discriminate oil emulsions within a detected oil slick has not been fully exploited. Additionally, one of the challenges in the past has been...
