DGS07-3 Bathymetric Digital Elevation Grids Offshore of New Jersey
   (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.
