Included are: \n(1) polygon extents; datasets that represent the aquifer system extent, the entire \nextent subdivided into subareas or subunits, and any polygon extents of special \ninterest (outcrop areas, no data available, areas underlying other aquifers, anomalies, \nfor example), \n(2) raster datasets for the altitude of each aquifer subarea or subunit, \n(3) altitude, and/or if applicable, thickness contours used to generate the surface rasters, \n(4) georeferenced images of the figures that were digitized to create the altitude and \nthickness contours. The images and digitized contours are supplied for reference.\n\t\t\t\nThe extent of the Southeastern Coastal Plain aquifer system is derived the linework in the \nSoutheastern Coastal Plain aquifer system extent maps in a digital version of the aquifer \nextent presented in the Groundwater Atlas of the United States (the U.S. Geological \nSurvey Hydrologic Atlas HA-730-F, -730-G, and -730-K. The Southeastern Coastal \nPlain aquifer system has 4 aquifer subunits, in order from the most surficial to the \ndeepest: A1: Chickasawhay River aquifer, A2: Pearl River Aquifer, A3: Chattahoochee \nRiver Aquifer, and A4: Black Warrior River Aquifer. \n\t\t\nThe altitude and thickness contours for each available subunit were digitized from \ngeoreferenced figures of altitude contours in U.S. Geological Survey Profession \nPaper 1410-B, (USGS PP 1410-B), and the resultant top and bottom altitude \nvalues were interpolated into surface rasters within a GIS using tools that create \nhydrologically correct surfaces from contour data, derive the altitude from the \nthickness (depth from the land surface), and merge the subareas into a single surface. \nThe primary tool was  \"Topo to Raster\" used in ArcGIS, ArcMap, Esri 2014. \nThe surface rasters were  corrected for the areas where the altitude of an underlying \nlayer of the aquifer exceeded altitude of an overlying layer.", "distribution": [{"@type": "dcat:Distribution", "accessURL": "https://doi.org/10.5066/P9W8761D", "description": "Landing page for access to the data", "format": "XML", "mediaType": "application/http", "title": "Digital Data"}, {"@type": "dcat:Distribution", "description": "The metadata original format", "downloadURL": "https://data.usgs.gov/datacatalog/metadata/USGS.f8e25f17-aa3a-49c1-8544-4e782dfc23f0.xml", "format": "XML", "mediaType": "text/xml", "title": "Original Metadata"}], "identifier": "http://datainventory.doi.gov/id/dataset/USGS_f8e25f17-aa3a-49c1-8544-4e782dfc23f0", "keyword": ["Alabama", "Black Warrior River Aquifer", "Chattahoochee River Aquifer", "Chickasawhay River aquifer", "Georgia", "Mississippi", "Pearl River Aquifer", "South Carolina", "Southeastern Coastal Plain aquifer system", "Tennessee", "USGS:f8e25f17-aa3a-49c1-8544-4e782dfc23f0", "United States", "aquifer", "aquifer system", "environment", "extent", "geoscientificInformation", "groundwater", "inlandWaters"], "modified": "2020-11-17T00:00:00Z", "publisher": {"@type": "org:Organization", "name": "U.S. Geological Survey"}, "spatial": "-91.717561479, 28.878651564, -78.153283178, 36.392158697", "theme": ["geospatial"], "title": "Geodatabase of the datasets used to represent the four subunits of the Southeastern Coastal Plain aquifer system, Alabama, Georgia, Mississippi, South Carolina, and Tennessee"}
