The UCSB Library's collection of aerial photography is the largest known such collection in an academic library: more than 2.5 million images. The collection dates back to the 1920s, and we can generally provide one photograph per decade for anywhere in California. Outside of California, we have unique collections that include areas of China, Central Asia, Africa, and the Pacific islands.
All requests to use our department's materials can be made prior to your visit using your Special Collections Research Account.

Traditional aerial photography is generally created using a large-format camera mounted on the underside of a fixed-wing aircraft. The resulting negatives reveal a straight-down (vertical) view of the landscape. Photographs are taken sequentially at set intervals, often with a significant amount of overlap. When two images overlap at least 60%, a stereoscopic, or 3D, view is created. The overwhelming majority of our aerial photographs fall into this category.
An individual set of photographs is referred to as a flight or a mission. A flight is often just that: a single takeoff and landing. Some flights are created over the course of a few days or, less frequently, over the course of a season. On very rare occasions, a flight may refer to a multi-year project (for example, our NAPP flights). A flight may contain a single photograph or tens-of-thousands. The UCSB Library has more than 4,500 flights which add up to more than 2.4 million individual images.
