Data Releases
The data collected and the techniques used by USGS scientists should conform to or reference national and international standards and protocols if they exist and when they are relevant and appropriate. For datasets of a given type, and if national or international metadata standards exist, the data are indexed with metadata that facilitates access and integration.

Survey monument positions for the Cleveland Corral landslide near U.S. Highway 50, El Dorado County, California (ver. 2.0, December 2024) Survey monument positions for the Cleveland Corral landslide near U.S. Highway 50, El Dorado County, California (ver. 2.0, December 2024)
Data in this document record the ground-surface positions from 1996 to 2018 of monuments located on different kinematic elements of the Cleveland Corral landslide, or on nearby more stable ground. Data were collected about once a year in campaign mode, at times when the landslide was dormant and not moving (typically late spring or fall). Survey timing was selected to identify wet-season...
Predictive soil property maps with prediction uncertainty at 30-meter resolution for the Colorado River Basin above Lake Mead Predictive soil property maps with prediction uncertainty at 30-meter resolution for the Colorado River Basin above Lake Mead
These data were compiled to demonstrate new predictive mapping approaches and provide comprehensive gridded 30 meter resolution soil property maps for the Colorado River Basin above Hoover Dam. Random forest models related environmental raster layers representing soil forming factors with field samples to render predictive maps that interpolate between sample locations. Maps represented...
Physical, Hydraulic, and Thermal Properties of Soils in the Noatak River Basin, Alaska, 2016 Physical, Hydraulic, and Thermal Properties of Soils in the Noatak River Basin, Alaska, 2016
This dataset includes physical, hydraulic, and thermal properties of soils collected in two sub-watersheds in the Noatak River Basin in northwestern Alaska. Physical properties include dry bulk density and porosity. Hydraulic properties include field- and lab-based hydraulic conductivity, soil-water retention data, and parameters used in a common soil-water retention model (van Genuchten...
Water Level, Temperature, and Discharge of Headwater Streams in the Yukon River Basin, Alaska, 2016 and 2017 Water Level, Temperature, and Discharge of Headwater Streams in the Yukon River Basin, Alaska, 2016 and 2017
This dataset includes 15-minute interval data on stream temperature, stage, and discharge from low-order streams in the Yukon River Basin in interior Alaska, collected during the summer months. The depth of the water and temperature were determined using a combined pressure transducer and temperature sensor that was deployed through the summer months. Different sensors were used in each...
National Land Cover Database (NLCD) 2016 Shrubland Fractional Components for the Western U.S. (ver. 3.0, July 2020) National Land Cover Database (NLCD) 2016 Shrubland Fractional Components for the Western U.S. (ver. 3.0, July 2020)
Quantifying Western U.S. shrublands as a series of fractional components with remote sensing provides a new way to understand these changing ecosystems. The USGS NLCD team in collaboration with the BLM has produced the most comprehensive remote sensing-based quantification of Western U.S. shrublands to date. Nine shrubland ecosystem components, including percent shrub, sagebrush...
Lanai habitat and ecological associations of two non-native ungulate species 2011 Lanai habitat and ecological associations of two non-native ungulate species 2011
This series of five raster datasets includes three input rasters developed to model habitat suitability for two ungulate species on the island of Lanai; the two habitat suitability model raster datasets are also part of this data release. Input datasets were derived from WorldView-2 data to create vegetation (hereafter, NDVI) and bare ground indices, and from a Digital Elevation Model...
