Linear Deconvolution Results For Site DS-3 (3-component-model)

Published by U.S. Geological Survey | Department of the Interior | Metadata Last Checked: January 27, 2026 | Last Modified: 2020-08-21T00:00:00Z
These geotiffs represent the raster GIS outputs of Linear Deconvolution (Linear Spectral Unmixing) analysis of ASTER image pixels covering various sand dune and sand sheet fields throughout the Western United States and Alaska. This particular dune field (DS-3) represents Bruneau Dunes, Idaho and surrounding and adjacent barren areas along the Columbia River Basalts province. The accompanying zip file contains linear deconvolution-derived mineral fractional abundance maps for a three-component mixture model of Quartz, Potassic Feldspars and "Lithic Non-Vesicular Basalt", as well as RMS and residual errors. Each geotiff layer has an associated metadata file with further details.
