The large-area material maps presented here were designed to aid in the identification of mineral groups in exposed rocks, soils, mine waste rock, and mill tailings on the Earth's surface. Data presented here come from two sources: ASTER, covering the northwestern and southwestern US; and Landsat 7, covering the entire conterminous US. Algorithms used to infer mineralogical composition of surficial materials from the source data were described in other reports, specifically USGS SIM 3190 for the ASTER data and USGS SIM 3252 for the Landsat 7 data.
