GPS Geodetic Reference System in Tennessee
Publication: Journal of Surveying Engineering
Volume 114, Issue 4
Abstract
Faced with diminished survey forces and a sparse geodetic reference system, the Tennessee Department of Transportation reduced its geodetic survey workload to a minimum. The introduction of Global Positioning System (GPS) technology provided a possible solution to the manpower problem but the need for a consistent statewide reference system remained. A cooperative effort between state, federal, and private sectors resulted in a highly accurate reference network of three‐dimensional points on a moderate budget. The network, designed specifically for GPS use, is tied to the National Geodetic Reference System using the National Geodetic Survey's very long baseline interferometry (VLBI) points as fiducial stations. Similar projects by other states would result in a national network of control points suitable for accuracies available through GPS and provide a framework for a national cadastre.
