Aerial Photographs

1950-1992

Series provides visual documentation of changes made to county lands through development and by natural and man-made disasters. The photographs are taken at intervals along a series of flight paths to attain coverage of all or part of a county. They generally include flight path or township, range, and section numbers; show natural and man-made features; and are produced in black and white or color prints to varying scales. An index by quadrant may also be included.

The searchable computer GIS database Survey Graphic Index available in the surveyor's office public research area and by paid subscription includes digital images of survey plats, road survey plats, subdivision and partition plats, aerial photographs, assessor's maps, as well as corner monumentation and other information.
