Digital Orthophotos of Washington State

An orthophoto is an aerial photograph that has been corrected for parallax and camera tilt. Most digital orthophotos are georeferenced; they know where they lie on the face of the earth. Although many other programs can display digital orthophotos, GIS software will automatically mosaic photos of adjacent areas, and can overlay other geographic information. If you do not have GIS software, we suggest the free arcexploer_9.2.

File sizes can be large, especially among those of us who spurn lossy compression.

Some of this imagery can be accessed by anyone through a browser. Some can also be used through an SDE server which is accessible only from the University of Washington campus. We hope to have a public data server within months.
