Average STATSGO Soil Characteristics for the Western United States This data set depicts soil characteristics in western North America. The data set was created from NRCS STATSGO soil data. Calculations were made to reduce one to many relationships to one to one relationships in order to summarize average water capacity, depth to rock, salinity, and pH for each map unit (MUID). ArcMap 8.3 was used to import .dbf files and merge newly created attribute fields to the GIS soil coverage. Tags: Arizona, California, Colorado, Idaho, Montana, All tags...

This index was based on 90-m resolution digital elevation model grids (DEM; National Elevation Dataset, USGS EROS [Earth Resources Observation Systems],3), and a landform model of the western United States (Manis et al. 2001), which delineates valley flats and near level plateaus or terraces (cell values, 1 or 4). We reclassified the landform model (cell value, 1) and multiplied this layer by the DEM to derive valley floor elevation. Using... Tags: Arizona, California, Colorado, Idaho, Montana, All tags...

Following Knight et al. (1995), we used linear features such as roads, railroads, and power line spatial data sets, but also included irrigation canals, to build a linear features spatial data set. However, we lacked spatial data on telephone and feeder-power lines and therefore our linear feature spatial data set vastly underestimates the number of linear features in some areas.

This is a static dataset even though liquid energy development is a highly dynamic endeavor. Because these well location datasets are generally housed and managed by various state-based agencies (typically the state Oil and Gas Conservation Commissions) a uniform, spatially precise coverage for the western United States has not been available to date. This layer consolidates the best available well location data from ND, SD, MT, WY, CO, NM, UT, AZ, OR, and CA (ID and WA do not report any liquid energy development) and standardizes the attributes.

Additionally, it contains total acreages of land enrolled in the CRP distributed by county and the contract year (1987-2003). USDA Farm Service Agency's (FSA) Conservation Reserve Program (CRP) is a voluntary program available to agricultural producers to help them safeguard environmentally sensitive land. Producers enrolled in CRP plant long-term, resource-conserving covers to improve the quality of water, control soil erosion, and enhance wildlife habitat. In return, FSA...
