Height Modernization Seminar
August 28, 2015
Dr. Gary Jeffress, RPLS
Welcome Address, Height Modernization, and History of Satellite Geodesy
Dr. Jeffress is a Professor of Geographic Information Science and Director of the Conrad Blucher Institute for Surveying and Science at Texas A&M University-Corpus Christi. He holds a Ph.D. in Surveying Engineering from the University of Maine, Master of Surveying Science (Geodesy) and Bachelor of Surveying degrees from the University of New South Wales. He currently sits on the NOAA Hydrographic Services Review Panel. He is Principal Investigator for the NGS sponsored Texas Height Modernization program, which is a partner in the Gulf Coast Spatial Reference Consortium (CSRC). CSRC organize and sponsor a variety of activities to help complete height modernization projects and reach stakeholders across Gulf state borders. He is a Registered Professional Surveyor in Texas and held surveying licenses in Maine and Australia. He is past-president of the Texas Society of Professional Surveyors and past-president of the Geographic and Land Information Society.
Mr. Bill Henning, LS
Best Methods for Real Time GNSS Positioning
Mr. Henning is a Registered Professional Land Surveyor with over 46 years of active experience in all phases of the land surveying profession. He has authored articles for professional journals and trade magazines on GNSS positioning as well as authoring an extensive guideline document on single base real-time GNSS positioning and spearheading a real-time network guideline document while working at NOAA’s National Geodetic Survey (NGS). He has been the project lead for new height modernization geodetic networks in county-wide projects in the U.S., where he planned, helped construct, processed, adjusted and managed new geodetic control systems using NGS guidelines. He has over 19 years of experience working with various GNSS manufacturers’ real-time positioning systems. Mr. Henning was awarded the Maryland Society of Surveyors “Surveyor of the Year” for 2013-14.
Dr. Daniel Prouty, NGS Geodetic Advisor
Using OPUS for Orthometric and Ellipsoid Heights
Dr. Prouty works for NOAA’s National Geodetic Survey and is the Geodetic Advisor for the State of Texas. He helps to ensure proper geospatial control and procedures are followed. As an Advisor, he helps to assist Federal, State, and local government agencies, academia, and the private sector in obtaining the best results from their surveying and mapping projects. Daniel has worked for the Conrad Blucher Institute for Surveying and mapping for over ten years before joining NGS in 2009. Daniel has a Doctoral degree in Ocean Engineering from the University of Southampton in the UK.
Mr. Denis Riordan, LS, NGS Geodetic Advisor
Geometric and Geopotential datums for 2022
Denis Riordan, PLS is a Geodesist with the National Geodetic Survey. He serves as the Geodetic Advisor in Mississippi and as the Regional Advisor to the states of Alabama, Florida, and Louisiana. He works to guide, assist, and support those that use NGS products and services (products like the National Spatial Reference System (NSRS), which is the foundation for position, height, distance, direction, gravity, and shoreline for the United States and its territories). He helps those in the surveying, mapping, GIS, and remote sensing fields, which are groups that frequently use NGS products and services. He holds a Bachelor of Science Degree in Surveying and Mapping, is licensed as a Professional Surveyor and Mapper in the State of Florida, and has worked for over ten years with private industry in the land surveying field prior to joining NGS.
