NIMA was created to exploit the potential of enhanced collection systems, digital processing technology and the prospective expansion in commercial imagery than its separate predecessor organizations.
NIMA states that is mission is to provide "timely, relevant, and accurate Geospatial Intelligence in support of national security".
The creation of NIMA brought together the Defense Mapping Agency (DMA), the Central Imagery Office (CIO), and the Defense Dissemination Program Office (DDPO) in their entirety; and the mission and functions of CIA's National Photographic Interpretation Center. Also included in NIMA are imagery exploitation, dissemination and processing elements of the Defense Intelligence Agency, National Reconnaissance Office and the Defense Airborne Reconnaissance Office.
The NIMA work force is populated by professionals in fields such as cartography, imagery analysis, marine analysis, the physical sciences, geodesy, computer and telecommunication engineering, and photogrammetry.
