Knight Library has over 700,000 aerial photographs from the 1930s to current.
Aerial photographs flown over Oregon in different years are a powerful tool in developing the history of a site and documenting its development.
We have posted and Aerial Photograph Times Series of the White Stag Block in Portland as an example. To access the photographs, use our Map and Aerial Photography Research Service which is free to Oregon University System patrons. A small labor fee is charged for non-Oregon University System patrons. We may be contacted at 541-346-4565 or email@example.com.
