Geodetic Surveys

The National Geospatial-Intelligence Agency (NGA) maintains several offices of the Geodetic Surveys Division which plans and executes field surveys worldwide in support of United States national interests. State-of-the-art conventional, satellite, magnetic, and gravity surveying techniques are used to collect, process and analyze data. Primary customers include the Department of Defense (DOD) military services, DOD agencies and DOD contractors. NGA international cooperation agreements are supported via joint survey projects. Additional customers (other U.S. agencies, non-governmental organizations, educational institutions, etc.) are serviced when requirements coincide.

NGA's Office of GEOINT Sciences Geodetic Surveying offices are located at several DOD locations throughout the United States where they provide precise geodetic surveying support and technical advice.
