Dr. Daniel T. Gillins is an assistant professor of civil engineering (geomatics) in the School of Civil and Construction Engineering at Oregon State University. He is a licensed professional land surveyor in Utah and Oregon.
With the future of NGS veering away from passive control points, surveyors must be prepared to establish vertical control networks using GPS. Daniel will guide us through examples of real life control networks and the accuracies established using Trimble Business Center and OPUS. He will also give us a background of why NGS is distancing itself from the passive control points that has been the backbone of surveying for half a century.
