Bathymetry of the Gulf of Maine (Polygons)

Description
This datalayer represents seafloor topography for the Gulf of Maine, extending from the Bay of Fundy south of New Brunswick to the Continental Shelf southeast of Nantucket. The linework in this layer came from an ArcInfo bathymetric contour coverage available through the U.S. Geological Survey's Coastal and Marine Geologic and Environmental Research program, part of its Woods Hole Field Center. MassGIS assembled the data into a polygon coverage stored in the NE library, named BATHYMGM. In ArcSDE the bathymetry data are stored in two layers, BATHYMGM_POLY and BATHYMGM_ARC. An annotation layer is ArcSDE is named BATHYMGM_ANNO_NAME.
