Description

The demise of the cold war and the development of the internet have vastly expanded international collaboration and partnership in many scientific endeavors. The science of geodesy has benefit immensely from these efforts. Significant advancements in space and terrestrial measurement systems such as the Global Navigation Satellite Systems (GNSS), Very Land Baseline Interferometry (VLBI), Satellite Laser Ranging (SLR) and Doppler Orbitography and Radio Positioning Integrated by Satellite (DORIS), have greatly improved our knowledge of earth orientation parameters including the knowledge of the location of Earth geocenter, Polar Wobble (Chandler Wobble) and tectonic plate velocities. National geodetic surveying and mapping agencies along with government and academic research institutes from across the globe now share vast amounts of positioning information with the International Earth Rotation and Reference System Service (IERS) headquartered in Paris, France. Periodically the IERS releases updated positional and velocity information for the network of stations providing this foundational information. From this network national organizations can ensure that their respective geodetic reference frames are kept up to date and consistent with the most current understanding of the motions of the planet. This class will review the efforts of the IERS and how NGS and the National Geospatial-Intelligence Agency (NGA) ensure the integrity of NAD 83 and WGS 84.

Dave Doyle joined the National Geodetic Survey in 1972, and held the position of chief geodetic surveyor at his retirement in January, 2013. He was responsible for the development, technical design and management of plans and programs that enhance the United States National Spatial Reference System. Mr. Doyle began his career as a geodetic surveyor in the U.S. Army in 1967. From 1970 to 1972 he worked for a private surveying company near Washington D.C. where he was responsible for completing boundary, topographic and engineering surveys while he pursued undergraduate studies in geodesy and mathematics at the George Washington University. During his time at NGS his experiences included all phases of geodetic triangulation, astronomic positioning, leveling, GPS data collection, data analysis, datum transformations, network adjustments, and data publication. He has also provided technical support to various countries for the modernization of national and regional geodetic reference systems in Caribbean and Central America, Africa, and the Pacific. Mr. Doyle’s activities also include 33 articles in national and local surveying publications and he has conducted more than 380 workshops and seminars detailing the numerous aspects of geodesy and the National Spatial Reference System.

Mr. Doyle is a past president of the American Association for Geodetic Surveying, a Fellow member of the American Congress on Surveying and Mapping, a charter member of the Geographic and Land Information Society, and he has served on the U.S. delegation to the International Federation of Surveyors. Mr. Doyle is also an active member of the District of Columbia, Maryland and Virginia surveyors’ professional associations and was awarded the 2008 Surveyor of the Year by the Maryland Society of Surveyors.
