This is a Vector data set. It contains the following vector data types (SDTS terminology):
Horizontal positions are specified in geographic coordinates, that is, latitude and longitude. Latitudes are given to the nearest 0.000000. Longitudes are given to the nearest 0.000000. Latitude and longitude values are specified in Decimal degrees.
The horizontal datum used is North American Datum of 1927.
The ellipsoid used is Clarke 1866.
The semi-major axis of the ellipsoid used is 6378206.400000.
The flattening of the ellipsoid used is 1/294.978698.
Sequential unique whole numbers that are automatically generated.

Selected by the Long Island Sound Study to serve as a general bathymetric data layer in its GIS data base. Best for sound-wide applications or general information. These data can be used with geographic information systems (GIS) software to display geologic and oceanographic information for the Long Island Sound. The data are to be used for illustrations and illustrative maps on scientific topics. They are intended for science researchers, students, policy makers, and the general public. There is NO ASSURANCE of their accuracy, completeness, or precision. The contour line data were manually digitized from a published map.
