Biographical / Historical:
The U.S. Army began aerial photography after World War I to free them from the time consuming and costly survey parties. Major James W. Bagley was placed in charge of the small engineer detachment at Wright Field to supply aerial photography for military mapping. The experiments of this time period produced methods of aerial mapping that opened up vast areas which would have been denied to a ground surveyor during World War II.
