New From David Rumsey Map Collection: San Francisco Aerial Photographs 1938

Super cool images and a great example of library collaboration.

From a Rumsey Map Collection Blog Post (With Highlights):

We have put online a set of 164 large format, sharp, black and white vertical aerial photographs of San Francisco taken in 1938 from an airplane by Harrison Ryker, a pioneer in aerial photography. The photographs overlap each other and cover the entire city. The resolution is generally better than one foot or even higher with high contrast features allowing visibility of even the paint striping on a basketball court.


The photographs are owned by the San Francisco Public Library and are a continuation of our collaboration with them on scanning and putting online important historical maps and views of San Francisco (including our prior collaboration on the 1905 San Francisco Sanborn Insurance Atlas).
