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.

Coastal National Elevation Database (CoNED) Applications Project
High-resolution coastal elevation data is required to identify flood, hurricane, and sea-level rise inundation hazard zones and other earth science applications, such as the development of sediment transport and storm surge models. Light detection and ranging (lidar) enables the rapid collection of very accurate elevation data over large areas, and during the last decade, airborne laser altimetry...Coastal National Elevation Database (CoNED) Applications Project
