Track: Surveying
Authors: Ryan Hunsicker, Bruce Joffe, Bruce Joffe

GIS database themes should be linked to geodetic control so that all layers align. How does the geodetic control network work? How do GPS measurements register with California's geodetic control network? A collaborative work group of surveyors, geodesists and GIS professionals explain in a panel presentation:
