The U.S. Geological Survey, a bureau of the Department of the Interior, provides support services for the NGAC. The NGAC was authorized under the Geospatial Data Act of 2018. The NGAC operates under the Federal Advisory Committee Act, enacted by Congress in 1972 to ensure that advice rendered to the executive branch by advisory committees, task forces, boards, and commissions formed by Congress and the President, be objective and accessible to the public. The Act formalizes a process for establishing, operating, overseeing, and terminating these advisory bodies.
