Throughout his distinguished career with the Aeronautical Chart and Information Center and Defense Mapping Agency, Dr. William C. Mahoney was a driving force for reshaping the interpretation and exploitation of imagery acquired from airborne and space-borne cameras. His mathematical formulations led to the development of new imagery exploitation equipment, such as the analytical stereo plotter, and supported application of the computer to mapping activities.

Analytical models he developed resulted in new concepts of digital terrain information and point positioning. To support these developments, Mahoney built a cadre of “superb professional support” in industry and in academia. He retired in 1986 as Director of Science and Technology at the DMA Aerospace Center in St. Louis. He was inducted into the National Geospatial-Intelligence Agency Hall of Fame in 2002.
