These data are a subset of categories and items from county-level data for the conterminous United States covering the census reporting years beginning with the 1950 Census of Agriculture and ending with the 2012 Census of Agriculture. Historical (1950-1997) data were extracted from digital files obtained through the Intra-university Consortium on Political and Social Research (ICPSR). More current (1997-2012) data were extracted from the National Agriculture Statistical Service(NASS) Census Query Tool for the census years of 1997, 2002, 2007, and 2012. Please refer to the Supplemental Information element of the metadata for information on the Census of Agriculture, the Inter-university Consortium for Political...

The National Hydrologic Geospatial Fabric (NHGF or the fabric) is a Water Mission Area (WMA) project focused on developing a web-accessible, middle-tier data system that will provide users access to the best-available geospatial data for hydrologic simulation modeling.

This data release consists of rasters representing the probability of exceeding multiple thresholds of nitrate in shallow groundwater for the Mid-Atlantic region of the United States. Each raster represents the results from multiple spatial-probability models that were developed using U.S. Geological Survey water-quality data in conjunction with geographic data such as land cover, geology, and soils. There are 10 rasters of predictions (PRED_1 through PRED_10) and 10 rasters of the highest possible probability (UPPER_1 through UPPER_10). The highest probability is the upper limit of the prediction confidence interval calculated as part of each model. Geospatial data provided are in the North American Albers equal-area...

This data release contains input data for hydrologic simulations of the Alaska Domain application of the U.S. Geological Survey (USGS) Precipitation Runoff Modelling System (PRMS) as implemented in the National Hydrologic Model (NHM) infrastructure (Regan and others, 2018). The NHM Alaska Domain parameter database consists of 114 parameter files in ASCII format (CSV), two files needed to run the Alaska Domain PRMS (control.fy19deliverable and fy19_deliv.param), two xml files (dimensions.xml and parameters.xml) containing descriptive information about the parameters, and a table that defines each parameter (AK_paramDB_datadictionary.csv). The Entity and Attribute element of this metadata record describe the data...

This polygon shapefile provides county or county-equivalent boundaries for the conterminous United States and was created specifically for use with the data tables published as Selected Items from the Census of Agriculture for the Conterminous United States, 1950-2012 (LaMotte, 2015). This data layer is a modified version of Historic Counties for the 2000 Census of Population and Housing produced by the National Historical Geographic Information System (NHGIS) project, which is identical to the U.S. Census Bureau TIGER/Line Census 2000 file, with the exception of added shorelines. Excluded from the CAO_STCOFIPS boundary layer are Broomfield County, Colorado, Menominee County, Wisconsin, and the independent cities...
