Description:

Abstract:

The Long Island Sound Study (LISS) compiled data from a number of different sources, integrated new data, and assembled a comprehensive spatial database for areas of the States of Connecticut, New York, and portions of Rhode Island which border Long Island Sound.

Purpose:

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.
