Uncle Sam spending $3,000,000 to make one map. Washington D.C. July 28. A huge photographic map which when completed will have cost $3,000,000, is being put together by the Agriculture Adjustment Administration, Department of Agriculture, in Washington. Approximately one-thrid of the entire land surface of the United States is being photographed from the air from a distance of three to five miles up. The idea behind this gigantic job is to determine compliance in the Agricultural Conservation Program, plan soil conservation or Public Works projects, lay out roads, forests and public parks, drainage ditches, dams and lakes and also to seek to improve National Defense. (1) C.E. Kowalczyk, AAA worker, is shown making a stereoscopic examination of the finished photographic prints to determine the relief or elevation of land surface. 7/28/37
