Our Seal and Symbolism

The NGA OIG seal effectively captures our values; the trifecta of “Independence, Integrity and Professionalism” and symbolizes our contribution to NGA mission success.

The globe of radiating star above the Earth, is inherited from our agency’s emblem and motto, “Know the World, Show the Way...from Seabed to Space.”

The radiating star above the Earth marks the Agency and OIG as purveyors of new concepts, technologies and products, while the day and night depiction suggests the perpetual nature of our efforts.

The red compasses symbolize true direction guided by integrity and professionalism and anchored in a foundation of independence.

The badge is a symbol of authority and independence, and encompasses a 12-point shield, representing the 12 original statutory federal Inspectors General that laid the groundwork for protecting taxpayer dollars by detecting and preventing fraud, waste and abuse in the federal government. As a statutory Inspector General, the NGA OIG is committed to promoting effectiveness and efficiency in Agency operations and programs.

“Integrity first, professionalism always; we stand on a foundation of independence.”
