USGS - science for a changing world

San Francisco Bay Area Regional Database (BARD)

The New BARD Content

As the digital mapping world has changed, BARD has also changed. Older formats of USGS data are no longer available at this site with the exception of elevation (DEM) data. Please visit the USGS Seamless web site, the USGS Store, or the National Map for more recent data.


USGS San Francisco Bay Area Mapping

Sample San Francisco 1915 mapBARD's goal is to provide USGS mapping data that is not readily available on other USGS data sites. These include historical maps for the Bay area, individual elevation (DEM) quadrangles (1:24,000 scale), and county compressed orthoimagery. Links to other USGS data such as bathymetry are also provided.

Several compression methods are used for the data. Directions for uncompressing the data files are listed on the download pages. However, uncompressing these files may require plug-ins or utility programs not provided by the USGS.

Comments about changes to the site are welcome. Please email the Web Team listed below.
