Accurate descriptions of horizontal positions are defined with respect to a reference surface or datum. This course will describe the general architecture of a horizontal/geometric datum and how that process has evolved since the early nineteenth century, including the evolution of the agencies now represented by the National Geodetic Survey (NGS), the process of triangulation and space-based positioning.


1. What are the fundamental elements of horizontal datums
2. History of horizontal datums in the United States
3. Procedures involved in geodetic triangulation
4. Advances in geodetic measurements
5. Evolution of space-based positioning
6. Datum differences and transformation tools

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.
