    • Linear Deconvolution Results For Site DS-8 (2-component-model-2)

    Metadata Updated: November 12, 2025

    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-8) represents crescentic and parabolic dune fields and portions of Alkali Flats playa of the White Sands National Monument, New Mexico. The accompanying zip file contains linear deconvolution-derived mineral fractional abundance maps for a two-component mixture model of Gypsum and Quartz, as well as RMS and residual errors. Each geotiff layer has an associated metadata file with further details.
