DGS06-1 Bathymetric Elevation Contours Offshore of New Jersey (Ten-Foot
This DGS consists of bathymetric elevation contour lines at ten foot
intervals off the New Jersey shore including parts of Delaware Bay, New York
Bay, Raritan Bay and Sandy Hook Bay. The bathymetric-elevation contour
lines range from -10 feet to -220 feet and extend 20 miles offshore. "Bathymetry"
data represents the water depth relative to sea level.
The shapefile was created from xyz ASCII grid data 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.
This data is not to be used for navigation. Although this data are of high
quality and useful for planning and modeling purposes, they do not necessarily
reflect current conditions, nor do they depict data which are on a nautical
chart. For navigation please refer to the NOS nautical chart series.
The bathymetry data are prepared for distribution as an ESRI shapefile.
The shapefile is combined with FGDC compliant metadata, layer file
and associated database files in a compressed 'zip' file for delivery over
