The Image Data Exploitation (IDEX) I system entered service in 1981 as the first computerized imagery processing system employed  by U.S. intelligence agencies.  Prior to IDEX, imagery was processed using film.  Even when images were collected digitally, they had to be converted to film to be analyzed.  IDEX II, built by Lockheed Missiles and Space, entered service in 1991 and over 100 workstations were deployed in the United States and overseas.  IDEX II was decommissioned in 2003.
