 "The USGS surveyor most closely associated with the development and use of the panoramic camera system in Alaska was Maj. James W. Bagley.In 1917, Bagley wrote USGS Bulletin 657, The Use of the Panoramic Camera in Topographic Surveying.In retrospect, the history, justification, technical information, documentary evidence, and mathematical formulas found in this bulletin make it one of the most important publications ever produced on the scientific uses of the panorama.
