This digital data release consists of an ARC/INFO grid and associated INFO tables. The grid is called MUID and has STATSGO (U.S. Department of Agriculture, 1994) soil mapping unit identifiers gridded on a 1-kilometer resolution for the conterminous United States. The INFO tables have soil characteristics data in them. The ITEMS in the tables are weighted average values for several soil characteristics in the STATSGO data base. The weighted average values were computed by aggregating the soil layers and components in the data base. The INFO tables are called MUID.LAYER, MUID.COMP, MUID.KFACT, MUID.TFACT, and MUID.WEG. The INFO tables can be related or joined to the MUID grid or to individual State coverages (grids or polygons) of MUIDs. Joining or relating the tables to the MUID grid creates 1-kilometer resolution grids of the soil characteristics for the conterminous United States. The soil characteristics in MUID.LAYER are permeability (PERML and PERMH in the STATSGO data base), available water capacity (AWCL and AWCH), bulk density (BDL and BDH), and organic matter (OML and OMH). The soil characteristics in MUID.COMP are slope (SLOPEL and SLOPEH), depth to seasonally high water table (WTDEPL and WTDEPH), and depth to bedrock (ROCKDEPL and ROCKDEPH). The soil characteristic in MUID.KFACT is the soil erodibility factor (KFACT), the soil characteristic in MUID.TFACT is the soil loss tolerance factor (TFACT), and the soil characteristic in MUID.WEG is the wind erosion group (WEG). The MUID grid and INFO tables were created with a set of arc macro language (aml) and Fortran programs. Send electronic mail to dwolock@usgs.gov to obtain copies of the computer code.

description: This digital spatial data set provides information on the magnitude and spatial pattern of depth-weighted, mean soil permeability throughout the State of Kansas. The data set was assembled using 1:24,000-scale cartographic and attribute information on the spatial distribution and characteristics of Kansas soils from the U.S. Department of Agriculture, Natural Resources Conservation Service (NRCS). The data set is in grid (raster) format with a grid-cell size of 10,000 square meters.; abstract: This digital spatial data set provides information on the magnitude and spatial pattern of depth-weighted, mean soil permeability throughout the State of Kansas.

A grid surface delineating soil permeability classes (Very slow, Slow, Moderate, High) for land areas across Tasmania at a spatial resolution of 30m. A grid surface delineating soil permeability classes (Very slow, Slow, Moderate, High) for land areas across Tasmania at a spatial resolution of 30m.

A collection of high-resolution soil attribute grid surfaces for land areas in Tasmania. There are 17 soil attribute products available that delineate specific soil properties at standardized soil depths (0-5cm, 0-15cm, 5-15cm, 15-30cm, 30-60cm, 60-100cm & 100-200cm) and grid resolutions (30m and 80m grid resolutions). Soil attributes available include Available Water Capacity (AWC, %), Bulk Density (BD, Mg/m3), Soil Texture (Clay; Sand; Silt, %), Coarse Fragments (CF, %), Soil Depth (cm), Soil Drainage, Electrical Conductivity (EC/ECse, dS/m), Field Capacity (FC), Soil Organic Carbon (SOC, %), Soil Permeability, pH, Exchangeable Calcium (ExCa, ppm), Exchangeable Magnesium (ExMg, ppm) and Depth to Sodic layer (Sodic Depth, cm).

Note that these products were developed using datasets held by the Tasmanian Department of Primary Industries Parks Water & Environment (DPIPWE) Soils Database, hosted on the Tasmanian Natural Values Atlas (https://www.naturalvaluesatlas.tas.gov.au/). The mapping was made by using spatial modelling and digital soil mapping (DSM) techniques with the outputs available via a Web Map Service (WMS):

This digital spatial data set provides information on the spatial distribution of potential runoff-contributing areas in Kansas. Potential runoff-contributing areas were estimated collectively for the processes of infiltration-excess overland flow and saturation-excess overland flow. For infiltration-excess overland flow, various rainfall-intensity and soil-permeability values were used. For saturation-excess overland flow, antecedent soil-moisture conditions and a topographic wetness index were used. The digital data sets used in the analysis included 1:24,000-scale soils data (U.S. Department of Agriculture, Natural Resources Conservation Service, 1996) and the U.S. Geological Survey (USGS) 100-meter-resolution digital elevation model (DEM) (U.S. Geological Survey, 1993). The data set of potential runoff-contributing areas is in grid (raster) format with a grid-cell size of 10,000 square meters.

Geographical grid dataset showing the soil cover in Flanders, condition 2021.This map has a focus on soil permeability, more specifically the ‘Water impermeability’. It has a hydrological context in which the loss of water permeability is important. Water impermeability is related to the surface where the soil surface has lost its infiltrability to water due to the application of an artificial water impermeable surface and thus where water flows through this surface. The map is displayed in percentage of water impermeability per pixel (5m resolution).

This dataset was produced by the U.S. Geological Survey (USGS) in cooperation with the Wyoming Water Development Office for the purpose of calculating basin characteristics in preparation for the Wyoming StreamStats application. These datasets are raster representations of various environmental, geological, and land use attributes with the Wyoming StreamStats study area and will be served in the Wyoming StreamStats application to describe delineated watersheds. The StreamStats application provides access to spatial analytical tools that are useful for water-resources planning and management, and for engineering and design purposes. The map-based user interface can be used to delineate drainage areas, get basin characteristics and estimates of flow statistics. To aid in parameterization of mechanistic, statistical, and machine learning models of hydrologic systems in the Wyoming StreamStats study area, flow-conditioned parameter grids (FCPGs) have been generated describing upstream basin elevation, slope, level III and IV ecoregion codes, hydrologic regions, land cover classification, waterbodies, first of the month snow water equivalent (Jan-Jun), soil type, average soil permeability, evapotranspiration Spring and Summer, and modeled 30-year normal climatologies of average annual total precipitation, average monthly total precipitation, average annual daily mean temperature, and average monthly daily mean temperature values within the Wyoming StreamStats study area.
