Linear Deconvolution Mineral Maps of Compositionally Variable Dune Fields in the Western United States and Alaska

February 23, 2018

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. The accompanying sets of zip file contains linear deconvolution derived mineral fractional abundance maps for various 2-, 3-, 4,- and 5-component mixture models of various dune-forming minerals, as well as RMS and residual errors for each model. Each geotiff layer has an associated metadata file with further details on each dune field and linearly deconvoled mineral distribution.
