Marine Beaches: MassGIS
Office of Geographic Information
The Massachusetts Department of Public Health (MDPH) Environmental Toxicology Program (ETP). has developed two Marine Beach data layers, one representing the actual linear extents of each beach, and the other a point layer of beaches' boundaries and access, sampling, and other locations. Data were collected as part of the BEACH Act, as administered by the U.S. Environmental Protection Agency. The beach points (based on GPS) are accurate to within 10 meters.
