Purpose: 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. Supplemental_Information: Additional information about the USGS field activity from which some of these data were derived is available online at: https://cmgds.marine.usgs.gov/fan_info.php?fan=S310SF Any use of trade, product, or firm names is for descriptive purposes only and does not imply endorsement by the U.S. Government. Although this Federal Geographic Data Committee-compliant metadata file is intended to document the data set in nonproprietary form, as well as in Esri format, this metadata file may include some Esri-specific terminology.
