Please recognize the U.S. Geological Survey (USGS) as the source of this information.
The purpose of this polygon feature class is to identify the spatial extent and provenance of the source data used to create the continuous elevation surface. In addition the shapefile will also provide an inventory of the most recent elevation and bathymetry datasets within the Massachusetts coastal zone and offshore water and identify areas of the offshore waters that are only covered by historical lead-line soundings and should be updated by using new survey methods.
