Surveying FS

Answer: A - The National Geodetic Survey determines if private survey control data is included in the National Spatial Reference System (NSRS). NGS’s mission is to define, maintain, and provide access to the consistent coordinate system (i.e., NSRS) that defines longitude, latitude, height, scale, gravity, and orientation throughout the United States. NGS collaborates with public and private organizations to establish reference stations at precisely determined locations.
