Published by National Geodetic Survey | National Oceanic and Atmospheric Administration, Department of Commerce | Catalog Last Checked: May 16, 2026 at 11:21 PM | Dataset Last Updated: January 01, 2020 at 12:00 AM
These data provide an accurate high-resolution shoreline compiled from imagery of CHOPTANK RIVER, MD . This vector shoreline data is based on an office interpretation of imagery that may be suitable as a geographic information system (GIS) data layer. This metadata describes information for both the line and point shapefiles. The NGS attribution scheme 'Coastal Cartographic Object Attribute Source Table (C-COAST)' was developed to conform the attribution of various sources of shoreline data into one attribution catalog. C-COAST is not a recognized standard, but was influenced by the International Hydrographic Organization's S-57 Object-Attribute standard so the data would be more accurately translated into S-57.
