Approximately 170 square kilometers of high-resolution multibeam bathymetric data were collected for Boston Harbor and its approaches. The data were gathered by the NOAA Ship Whiting in 2000 and 2001, then reprocessed and gridded by the Massachusetts Office of Coastal Zone Management and the U.S. Geological Survey. It provides boundary polygons for the seafloor measurements.
Use Cases
- Modeling seafloor topography using bathymetric boundary polygons.
- Analyzing changes in harbor approaches from the gridded survey data.
- Integrating multibeam sonar boundaries with other coastal geospatial datasets.
Strengths
- Covers approximately 170 square kilometers of seafloor.
- Data was reprocessed and gridded by authoritative agencies CZM and USGS.
Limitations
- Data is from 2000-2001 and may not reflect current seafloor conditions.
- Specific row counts, column details, and data formats are unknown.
