Hillshade of Composite Bathymetry 30 meter/pixel of Boston Harbor and Approaches

These data are high-resolution bathymetric measurements of the seafloor from Boston Harbor and the harbor approaches, Massachusetts. Approximately 170 kmĀ² of sidescan sonar and bathymetric data were collected by the National Oceanic and Atmospheric Administration (NOAA) Ship Whiting in 2000 and 2001 and reprocessed and gridded by the Massachusetts Office of Coastal Zone Management (CZM) and the U.S. Geological Survey (USGS). Note: These data were converted from their native projection to the Massachusetts State Plane coordinate system, Mainland Zone (Fipszone 2001), meters by the Massachusetts Department of Coastal Zone Management on Oct. 1, 2006.
