Linear Deconvolution Results For Site DS-5 (5-component-model)

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-5) represents the Great Sand Dunes of Colorado. The accompanying zip file contains linear deconvolution-derived mineral fractional abundance maps for a five-component mixture model of Quartz, Gypsum, Magnetite, Plagioclase and Potassic Feldspars, as well as RMS and residual errors. Each geotiff layer has an associated metadata file with further details.
