Abstract
Excerpts: The comprehensive listing shows the various photographic coverages used by the U.S. Department of Agriculture archived at the Aerial Photography Field Office. This library includes photography used by the Agriculture Stabilization and Conservation Service (ASCS) and it predecessor agencies, the U.S. Forest Service (FS) and the Soil Conservation Service (SCS). Coverage of the Agricultural Stabilization and Conservation Service and the Soil Conservation Service is listed alphabetically by states and counties. A Federal Information Processing Standards (FIPS) numerical code is assigned to each county flown by ASCS and SCS after July 1, 1971. Coverage of Forest Service photography is listed alphabetically for each forest within a region. Numerical codes used to identify FS projects are assigned by the Forest Service. Rectified enlargements are available from photography used for ASCS programs. This means that scale, tip, and tilt data, computed through an analytical aerotriangulation system, is available to produce true-to-scale enlargements for indicated projects.
