  • The National Geospatial-Intelligence Agency (NGA) is a Department of Defence combat support agency and a member of the national Intelligence Community (IC). NGA develops imagery and map-based intelligence solutions for U.S. national defence, homeland security and safety of navigation. NGA provides timely, relevant and accurate geospatial intelligence in support of national security objectives. The term “geospatial intelligence” means the exploitation and analysis of imagery and geospatial information to describe, assess and visually depict physical features and geographically referenced activities on the Earth. Geospatial intelligence consists of imagery, imagery intelligence and geospatial (e.g., mapping, charting and geodesy) information. Information collected and processed by NGA is tailored for customer-specific solutions. By giving customers ready access to geospatial intelligence, NGA provides support to civilian and military leaders and contributes to the state of readiness of U.S. military forces. NGA also contributes to humanitarian efforts, such as tracking floods and disaster support, and to peacekeeping.
