Topobathymetric Elevation Model of San Francisco Bay Area, California
Accurate, high-resolution elevation information is vital to understanding the natural hazards that can impact the highly populated San Francisco Bay area, such as sea-level rise, winter storms, cliff erosion, and other coastal hazards. The San Francisco Bay estuary three-dimensional (3D) topobathymetric digital elevation model (TBDEM) was developed in collaboration between U.S. Geological Survey (USGS) Coastal and Marine Geology Program, USGS National Geospatial Program, San Francisco State University, State of California Ocean Protection Council, National Oceanic and Atmospheric Administration, and California State University, Monterey Bay Seafloor Mapping Lab.
The 2-meter resolution TBDEM seamlessly integrates 42 land elevation and water depth (bathymetry) datasets collected during the time period of 1922 to 2010. The most recent and/or accurate datasets are prioritized, including high-resolution airborne lidar surveys and ship-based multibeam bathymetric surveys, while older datasets are used to fill in gaps in coverage.
