Access USGS - San Francisco Bay and Delta
As of April 27, 2009, older formats of USGS data are no longer available with the exception of elevation (DEM) data. However, scanned historical 15-minute and 30-minute maps are still available. The site also has mosaicked (MrSid compressed) county orthoimagery and mosaicked San Francisco orthophotos from 1993 and 1946. Descriptions of these data types, what the data can be used for, and specific download instructions are all included on this Web site.
"Cooperative Research & Development between Pacific Gas & Electric Company and the USGS to promote informed decisions about reducing Earthquake Risks in the San Francisco Bay Area."
Portfolio of images of landscape, seascape and faults of the San Francisco Bay area
These images drape Landsat TM satellite imagery over Digital Elevation Models to show the bay as it has never been seen before. Earthquake fault lines are displayed in red.
All the images can be downloaded quickly for printing from your home computer on US Letter paper. Full size 6ft images can be downloaded or ordered from this site, or you can take a file to any good copy service bureau that offers a poster printing service.
