State Geodetic Coordinators

The State Geodetic Coordinator is a designee of a state government agency or university and is not an NGS employee. The Coordinator serves as a liaison between the state and NGS. State Coordinators should have technical expertise in geodesy to make informed decisions and provide guidance for geospatial activities that benefit from connecting to the NSRS. The State Geodetic Coordinator is a primary point of contact for the Regional Geodetic Advisor in their state.
