The U.S. Geological Survey (USGS) and the Department of Energy (DOE) have collaborated to acquire high-resolution airborne magnetic and radiometric data, over northern and western Nevada and eastern California, to support geologic and geophysical mapping and modeling that will assist geothermal and critical mineral studies. The surveys, referred to as GeoDAWN (Geoscience Data Acquisition for Western Nevada), span areas of major resource potential associated with the Walker Lane and western Great Basin. They were conducted under the USGS’s Earth Mapping Resource Initiative (EarthMRI), with support from the DOE’s Geothermal Technologies Office (GTO), and involved acquisition of aeroradiometric and aeromagnetic data...

The raster-based classification of evapotranspiration (ET) units is for nine major discharge areas in the Death Valley regional flow system. The ET units delineate general areas of similar vegetation and soil-moisture conditions. Classifications were derived from Landsat Thematic Mapper imagery data acquired June 13, 1992; Sept. 1, 1992; and June 21, 1989.
These data were released prior to the October 1, 2016 effective date for the USGS’s policy dictating the review, approval, and release of scientific data as referenced in USGS Survey Manual Chapter 502.8 Fundamental Science Practices: Review and Approval of Scientific Data for Release. The raster-based Modified Soil Adjusted Vegetation Index was derived from Landsat Thematic Mapper imagery data acquired during June 1992 for the Death Valley regional flow system. The index has been shown to increase the dynamic range of the vegetation signal while further minimizing the soil background influences, resulting in greater vegetation sensitivity as defined by a "vegetation signal" to "soil noise" ratio. The data set...
