The region encompasses major cities and metropolitan areas of San Francisco, Oakland, and San Jose, along with smaller urban and rural areas.

Several bridges can be observed as white lines spanning the estuaries, including the San Francisco-Oakland Bay Bridge (east of San Francisco), the Golden Gate bridge (north of San Francisco) and the Richmond-San Rafael Bridge (northeast of San Francisco), the northernmost of the east–west crossings of the San Francisco Bay in California, USA, connecting Richmond on the east to San Rafael on the west end.

USA - December 27th, 2011

This orthorectified image shows the city of San Francisco and the San Francisco Bay Area, a region of 7.15 million people in California, USA. It encompasses a land area of about 46.9 square miles (121 km2) on the northern end of the San Francisco Peninsula, giving it a density of about 17,179 people per square mile (6,632 people per km2). It is the most densely settled large city (population greater than 200,000) in the state of California and the second-most densely populated large city in the United States after New York City. Here, this area appears bright white.

What is frequently referred to as the San Francisco Bay is actually a system of several interconnected bays: the San Francisco Bay (bottom) is connected to the San Pablo Bay, which in turn is joined with the Suisun Bay, above the image center. Here, the bridges spanning these bays can be observed as thin white lines over the dark black waters. These are, moving from just above the center to the lower right corner of the full image, the Richmond-San Rafael Bridge, the San Francisco-Oakland Bay Bridge, the San Mateo-Hayward Bridge, and the Dumbarton Bridge.
