It is based primarily on shoreline data with horizontal positional accuracy of +/- 2meters provided by the Virginia Institute of Marine Science (VIMS) Center for Coastal Resources Management (CCRM), with minor modifications in seven locations.  In six instances, the modifications were made using the National Oceanic and Atmospheric Administration's (NOAA) zero-foot sea level rise dataset, which represent mean higher high tide.  In one instance, a modification was made using the Chesapeake Bay Program Modified Watershed Boundary layer.  These modifications were as follows:\n-\tAdded the Delaware portion of the tidal Nanticoke River from the NOAA dataset.\n-\tAdded a braided channel in the Anacostia River in Washington, DC at Kingman Island from the NOAA dataset.\n-\tWidened the Anacostia River in Washington, DC at the Washington Navy Yard to match the NOAA dataset.\n-\tShortened the Rappahannock River to match the NOAA dataset.\n-\tShortened the York River to match the NOAA dataset.\n-\tShortened the Pamunkey River to match the NOAA dataset.\n-\tThe mouth of the Chesapeake Bay was modified to match the Chesapeake Bay Program Modified Watershed Boundary layer.", "distribution": [{"@type": "dcat:Distribution", "accessURL": "https://doi.org/10.5066/P9W3CTUW", "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.647641fed34e4e58932da218.xml", "format": "XML", "mediaType": "text/xml", "title": "Original Metadata"}], "identifier": "http://datainventory.doi.gov/id/dataset/USGS_647641fed34e4e58932da218", "keyword": ["shore", "tidal shoreline", "USGS:647641fed34e4e58932da218"], "modified": "2024-09-10T00:00:00Z", "publisher": {"@type": "org:Organization", "name": "U.S. Geological Survey"}, "spatial": "-77.4172, 36.6708, -75.3777, 39.6876", "theme": ["geospatial"], "title": "Chesapeake Bay Tidal Shoreline, Chesapeake Bay Program Phase 7 Model"}
