Topobathymetric Digital Elevation Model (TBDEM) of the Eastern Shore Peninsula of Virginia and adjacent parts of Maryland with a horizontal resolution of 1 meter and vertical resolution of 1 centimeter
Description
This topobathymetric digital elevation model (TBDEM) represents topography and bathymetry for the Eastern Shore peninsula of Virginia, including Accomack and Northampton counties, and extending into Worcester and Somerset counties in Maryland. The TBDEM has a horizontal grid spacing of 1 meter and vertical units of 1 (integer) centimeter. This dataset combines U.S. Geological Survey (USGS) Earth Resources Observation and Science (EROS) Center Coastal National Elevation Database topobathymetric DEM (CoNED TBDEM) data with data from the USGS Northern Atlantic Coastal Plain DEM, the latter of which were used to extend the bathymetric surface further offshore. In some areas, National Map 3D Elevation Program (3DEP) data were used to correct irregularities in the CoNED topographic surface. Horizontal coordinates are referenced to the Geographic Coordinate System World Geodetic System Datum of 1984 (GCS WGS 1984) and vertical measurements are referenced to the Vertical Datum of NAVD88 (North American Vertical Datum of 1988). The projected coordinate system is Albers Conic Equal Area with linear units of 1 meter, a central meridian of -96.0, standard parallels of 29.5 and 45.5, and a latitude of origin of 23.0.
