UGS Aerial Imagery Collection

The UGS Aerial Imagery Collection contains aerial photography of Utah originally taken from 1935 to the present, and includes over 125,000 frames and associated indexes, orthophotomaps (semi-controlled orthophotos), and other materials. Aerial photographs are highly sought after for use in geologic, geotechnical, and environmental investigations to document geologic hazards, land-use, geomorphologic, and other changes that may have occurred in a particular area, along with mapping geology, cultural, and vegetation features. The collection contains scanned images of aerial photograhs of Utah and a 0.2 degree buffer beyond the boundaries of Utah from 1935 to the present. Imagery indexes are available in the UGS GeoData Archive System.
