Welcome to the Oregon Atlas of Panoramic Aerial Images, one of a series of collections of photorealistic aerial views created by Dr. William A. Bowen, professor emeritus of the Department of Geography at California State University Northridge. The atlas contains 516 computer generated panoramas that portray every square foot of the state. Seeing the Earth from a high place allows us to grasp quickly the essential geography of vast regions that eludes those who are earth bound. Most of these panoramas were created from a virtual elevation of 40 kilometers (24.85 miles) above sea level with a virtual 35 mm camera equipped with a 22 mm lens. Normally the vistas encompass more than a thousand square miles (259,000 hectares) of the earth's surface.

Because of our lack of geographic experience and the unusual perspectives offered by this atlas, I recommend that users acquire a copy of a detailed state atlas such as those published by
Benchmark Maps and DeLorme. These may be purchased from your local bookseller, Amazon.com, or any one of many other dealers. Equipped with such a reference, atlas users will be able to orient themselves better and identify all manner of detail.

One of the unfortunate realities of Web publications is that every user's computer screen will render the panoramas differently. Serious users may need to download the images and modify their color balance using their own software. The pictures are best viewed on a large monitor.

It is hoped that these unique aerial views will provide a new and valuable resource for those who seek to understand better the character of Oregon's many landscapes and the people who occupy them. Other atlases in the Survey's
Electronic Map Library cover the states of Alaska, Arizona, California, Oregon, Nevada, Montana, Utah, and Washington. Future publications will include Colorado, New Mexico, and Wyoming. In addition, a general World Atlas is under development continuously.

California Geographical Survey is a creation of Dr. William A. Bowen, professor of geography emeritus, and formerly a long-time member of the California State University, Northridge faculty. The Survey operates for the benefit of the students and faculty throughout the world. It is the California Geographical Survey's intention to provide a variety of important geographic resources to the entire Internet community.

The materials of the California Geographical Survey ( http://californiageographicalsurvey.com/) are available without restrictions to scholars for non-profit, classroom use.

Bill lives in Roseville, California, far from the university he served for thirty-four years. Bill was educated as a geographer at U.C. Berkeley. He was privileged to have taken courses from Professors Clarence Glacken, John Kesseli, Ted Oberlander,
James Parsons, Carl Sauer, Hilgard Sternberg, James Vance, Gunther Barth, Peter Birkeland, J. B. Jackson, and George Stewart. He joined the faculty at California State University, Northridge in 1970 and taught there until his retirement in 2004. Several years before his retirement, he decided to create the California Geographical Survey as a tool for better communicating his ideas and maps to students and other explorers who frequent the Web. He continues his work today at home, in a closet that contains two high-speed Macintosh computers.

Although educated as a cultural geographer and physical geographer in the Sauerian tradition, he has always been fascinated with maps. This evolving collection of photorealistic, panoramic maps of the earth's landscapes can be traced to an undergraduate map reading course taught by Professor John E. Kesseli in 1962 and a cartography course taught by Professor Ted Oberlander in the Spring of 1963. He is forever in the debt of these fine scholars and the many other teachers who touched his life.
