This webinar covers the GPS Dilutions of Precision (DOPs), which are diagnostic tools provided to surveyors using GPS receivers to help know whether the precision of their work meets their standards. In this webinar the DOPs are defined mathematically and geometrically, and illustrated with real-world examples. The learning objectives are 1) be able to name the DOPs, 2) define the DOPs in terms of standard deviations, 3) explain what information is best provided by each DOP, 4) describe the range of the DOPs and give a general notion of what are “good” values and “bad” values, and 5) explain how DOPs can guide fieldwork.


 Tom Meyer was awarded a Ph.D. from Texas A&M University in College Station, Texas in 1998, where he was a research associate in the Mapping Sciences Laboratory. He now is a Professor of Geodesy in the Department of Natural Resources and the Environment at the University of Connecticut, where he teaches courses in land surveying, geomatics, GNSS surveying, geodesy, and spatial statistics. Dr. Meyer was named a UConn Teaching Fellow in 2015. He is also a Fellow and the 2016 President of the American Association for Geodetic Surveying (AAGS), a member of the American Society of Civil Engineers (ASCE), the National Society of Professional Land Surveyors (NSPS), and the Connecticut Association of Land Surveyors. Dr. Meyer is on the editorial boards of the Journal of Surveying Engineeringand Surveying and Land Information Science, has published an undergraduate textbook on geodesy and numerous peer-reviewed journal articles. He is a regular presenter at national meetings, giving workshops and seminars on numerous topics in geodesy, GNSS, and surveying.
