The Jack Ammann Photogrammetric Engineers Texas Aerial Photographs Sub-Series contains a set of Aerial Photographs of Central and Southwest Texas produced by the Jack Ammann Photogrammetric Engineers Company. Used by geologists and oil companies to examine terrain and map pipelines, these oversized prints consist of stitched together photographs that present middle altitude views of Texas at a 1"=20,000' scale.

The aerial photographs are arranged by directional set and flight number when available. Additional photographs include smaller scale views of the Rio Grande Dam Site.
