Aerial photography coverage is only for selected areas in Washington State, with an emphasis on the Puget Sound region, in a variety of scales, from 1944 to the present. Digital orthophotography available on the Geospatial Data Resources Guide (formerly WAGDA) website (1990's- present) supplements our paper collection.
Selected print satellite images show entire countries, large areas of the Pacific Northwest, and some states. Digital satellite imagery of Washington State is available on CD-ROM and for other locales at the Geospatial Data Resources Guide (formerly WAGDA) website.
The best way to locate aerial photography coverage for an area you are interested in is to follow the steps below. The first steps can be done online or in the Map Collection.

Digital Aerial Photography
See Geospatial Data Resources Guide (formerly WAGDA). Some of the digital imagery access is limited to UW students, faculty and staff.
Print satellite images are filed in the General Map Cases (with other thematic maps of that geographic area). Digital satellite imagery of Washington state is available on CD-ROM, and filed in Maps Media (ask Map Collection staff for assistance). Additional satellite imagery resources are linked to the Geospatial Data Resources Guide (formerly WAGDA). Due to their extremely large file size, they are not available online.
1. We can tell you project names, dates and scales that show your general area of interest (in Washington State).
2. We can check project base maps for photo coverage of one particular site.
Remote-sensing imagery is the term which encompasses all kinds of photographs taken remotely, i.e. from an aircraft or satellite.
Aerial photography is a series of photographic images of the ground, taken at regular intervals from an airborne craft such as an airplane. Most aerial photographs are 9" x 9" prints. Most photo enlargements are approximately 16" x 20" (for greater detail).
Orthophotographs are aerial photographs which have been orthorectified (adjusted digitally or otherwise) to remove displacements caused by the camera and the terrain. (Definition adapted from Terraserver.com's Geographic Glossary.)
Satellite images are taken from satellites, which orbit the earth at much higher altitudes than do airplanes. Satellites use a variety of methods to produce images, including infrared, water vapor, and visible image technologies. (For detailed explanations of these methods, go to NASA's Global Hydrology and Climate Center.)
