Digital Geodata Series
DGS07-3 Bathymetric Digital Elevation Grids Offshore of New Jersey

IMAGEMETADATADOWNLOAD (69.5MB)


Abstract

A set of ESRI GRID digital elevation themes with 100-ft. cells has been compiled for bathymetry offshore of New Jersey including parts of Delaware Bay, New York Bay, Raritan Bay and Sandy Hook Bay.  These data were generated using point data having 3-axis (x, y and z) spatial coordinates obtained from The National Ocean & Atmospheric Administration (NOAA), National Geophysical Data Center (NGDC), Coastal Relief Model Development Program.  The data originated from a vast compilation of hydrographic soundings collected by the National Ocean Service (NOS) and various academic institutions.  The grid data is georegistered to the NAD83, N.J. State Plane (Feet) Coordinate system.  "Bathymetry" data represents the measurement of ocean depths and the charting of the topography of the ocean floor.  The bathymetric-elevation grid elevations range from -0.3 feet to -225.2 feet. 

DGS07-3 includes 1 elevation grid, 1 shaded-relief (hillshade) grid for mapping purposes and 1 ESRI ArcMap shade layer at ten foot intervals for project use.
