The NHDPlus includes a stream network (based on the \n1:100,00-scale NHD), improved networking, naming, and value-added attributes (VAAs). \nNHDPlus also includes elevation-derived catchments (drainage areas) produced using a \ndrainage enforcement technique first widely used in New England, and thus referred to as \n\"the New England Method.\" This technique involves \"burning in\" the 1:100,000-scale NHD \nand when available building \"walls\" using the National Watershed Boundary Dataset (WBD). \nThe resulting modified digital elevation model (HydroDEM) is used to produce hydrologic \nderivatives that agree with the NHD and WBD. Over the past two years, an interdisciplinary \nteam from the U.S. Geological Survey (USGS), and the U.S. Environmental Protection Agency \n(USEPA), and contractors, found that this method produces the best quality NHD catchments \nusing an automated process (USEPA, 2007). The NHDPlus dataset is organized by 18 \nProduction Units that cover the conterminous United States.\n\t\t\nThe NHDPlus version 1.1 data are grouped by the U.S. Geologic Survey's  Major River Basins \n(MRBs, Crawford and others, 2006).  MRB1, covering the New England and Mid-Atlantic River \nbasins, contains NHDPlus Production Units 1 and 2.  MRB2, covering the South Atlantic-Gulf \nand Tennessee River basins, contains NHDPlus Production Units 3 and 6.  MRB3, covering the \nGreat Lakes, Ohio, Upper Mississippi, and Souris-Red-Rainy River basins, contains NHDPlus \nProduction Units 4, 5, 7 and 9.  MRB4, covering the Missouri River basins, contains NHDPlus \nProduction Units 10-lower and 10-upper.  MRB5, covering the Lower Mississippi, Arkansas-White-Red, \nand Texas-Gulf River basins, contains NHDPlus Production Units 8, 11 and 12.  MRB6, covering the \nRio Grande, Colorado and Great Basin River basins, contains NHDPlus Production Units 13, 14, 15 \nand 16.  MRB7, covering the Pacific Northwest River basins, contains NHDPlus Production Unit 17.  \nMRB8, covering California River basins, contains NHDPlus Production Unit 18.", "distribution": [{"@type": "dcat:Distribution", "accessURL": "https://doi.org/10.5066/P9J3E7CY", "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.9ea05850-b15d-4785-8b56-747691a85316.xml", "format": "XML", "mediaType": "text/xml", "title": "Original Metadata"}], "identifier": "http://datainventory.doi.gov/id/dataset/USGS_9ea05850-b15d-4785-8b56-747691a85316", "keyword": ["30-year average annual precipitation", "CALI", "COGB", "California", "Catchment", "Conterminous United States", "GLMR", "Great Lakes, Ohio, Upper Mississippi, and Souris-Red-Rainy", "Inlandwaters", "LMTG", "Lower Mississippi, Arkansas-White-Red, and Texas-Gulf", "MORI", "MRB", "MRB1", "MRB2", "MRB3", "MRB4", "MRB5", "MRB6", "MRB7", "MRB8", "Major River Basin", "Missouri", "NAWQA", "NEMA", "NHDPlus", "New England and Mid-Atlantic", "PANW", "Pacific Northwest", "Rio Grande, Colorado, and Great Basin", "SAGT", "SPARROW", "South Atlantic-Gulf and Tennessee", "USGS:9ea05850-b15d-4785-8b56-747691a85316", "elevation", "geoscientificInformation", "inlandWaters"], "modified": "2020-11-17T00:00:00Z", "publisher": {"@type": "org:Organization", "name": "U.S. Geological Survey"}, "spatial": "-127.910792, 23.243486, -65.327751, 51.657387", "theme": ["geospatial"], "title": "Attributes for NHDPlus Catchments (Version 1.1) for the Conterminous United States: 30-Year Average Annual Precipitation, 1971-2000"}
