The image is a composite of spectral bands 2, 4, and 7 in RGB (Red-Green-Blue) space. Individual bands were processed to display their full dynamic range. The image was further processed in hue-saturation space to emphasize specific geologic features. The image was a base reference for field reconnaissance work and for developing of the DVRFS transient ground-water flow model. The DVRFS flow model is one of the most recent in a number of regional-scale models developed by the U.S. Geological Survey (USGS) for the U.S. Department of Energy (DOE) to support investigations at the Nevada Test Site (NTS) and at Yucca Mountain, Nevada (see "Larger Work Citation", Chapter A, page 8). The Landsat 5 false-color composite image of the DVRFS was used as a reference map for planning and conducting field reconnaissance work within the DVRS study area. The image was also shown as a reference layer in maps developed for the DVRFS project. The false-color composite image is one of many layers in a geospatial data base supporting the USGS DVRFS project. During this 5-year (1998-2004) project the USGS, in cooperation with DOE and other Federal, State, and local agencies, developed this geospatial data base for a regional-scale, 3D hydrogeologic framework model (HFM) and a ground-water flow model. The models are intended to address water-resource issues and the potential movement of radioactive material from the Nevada Test Site and the proposed high-level nuclear waste repository at Yucca Mountain, Nevada. Data from two previous ground-water flow models of the greater Death Valley region (see "Larger Work Citation", Chapter A, p. 7) were the foundation of the DVRFS geospatial database. These and other data were reexamined through a series of regional-scale hydrologic investigations to provide updated and spatially consistent interpretations for the DVRFS study. In some cases, new data were collected to augment the existing information. Data compiled from the studies include natural ground-water discharge occurring through evapotranspiration and spring flow; ground-water pumping for the period 1913-98; ground-water recharge simulated as net infiltration; ground-water inflow and outflow at lateral model boundaries; hydraulic conductivity and its relation to depth and other rock properties; and the estimation of water levels representative of prepumped and pumped conditions in the region. Digital elevation models, geologic maps, borehole information, cross sections, and other 3D models were used to develop the HFM which represents the geometry of 27 hydrogeologic units and structural features. The resulting geospatial data base supports characterization and conceptualization of the DVRFS, construction of 3D hydrogeologic framework and ground-water flow models, and visualization of analysis and model results. 1996 ground condition Complete None planned -118.091443 -114.860392 38.551827 34.929890 USGS Water Basics Glossary.

The raster-based, false-color composite of the DVRFS region was derived from Landsat 5 Thematic Mapper (TM) data collected April 5, 14, and 28, 1996. The image is a composite of spectral bands 2, 4, and 7 in RGB (Red-Green-Blue) space. The image was further variably processed in hue-saturation-intensity space to emphasize specific features useful for identifying and mapping surficial deposits, such as desert varnish, pavement development, and various compositional components in surficial deposits (e.g., carbonate, sodium salts, feldspar), in order to produce pseudo-color images that approximate and locally enhance the appearance of natural-color aerial photographs. Individual Landsat scenes were hand-registered and clipped or mosaiced to match the 21 U.S. Geological Survey 1:100,000-scale topographic quadrangle boundaries covered by the DVRFS. The quadrangle images were subsequently compiled into one image and compressed using LizardTech MrSID software to reduce the file size. Data are available from USGS/EROS, Sioux Falls, SD.
