Foxgrover 2020 High-resolution (1 m) digital elevation model (DEM) of San Francisco Bay, California, created using bathymetry data collected between 1999 and 2020 2.0 data release DOI:10.5066/P9TJTS8M Pacific Coastal and Marine Science Center, Santa Cruz, CA U.S. Geological Survey https://doi.org/10.5066/P9TJTS8M Polygon shapefile showing the footprint boundaries, source agency origins, and resolutions of compiled bathymetric digital elevation models (DEMs) used to construct a continuous, high-resolution DEM of the central portion of San Francisco Bay. These data were compiled using new techniques to create a high-resolution DEM of the central portion of San Francisco Bay, which will be used to document and assess changes in seafloor morphology. These data are intended for science researchers, students, policy makers, and the general public. These data can be used with geographic information systems (GIS) or other software to identify elevations. These data are not intended to be used for navigational purposes.
