    • Linear Deconvolution Results For Site DS-1 (2-component-model-1)

    Metadata Updated: July 6, 2024

    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-1) represents the Algodones Dunes near the Salton Sea of Southern California. The accompanying zip file contains linear deconvolution-derived mineral fractional abundance maps for a two-component mixture model of Quartz and Potassic Feldspars, as well as RMS and residual errors. Each geotiff layer has an associated metadata file with further details.
