Description

This webinar will present the different means a geospatial professional may use GNSS to establish survey grade site control. Static GNSS Programs, such as NOAA’s National Geodetic Survey (NGS) Online Positioning User Service (OPUS) and GNSS manufacturers’ processing software, will be summarized. The concepts of NGS-58 and NGS-59 static guidelines will be contrasted to those of the OPUS-Project application. The ease of bringing accurate 3D + ortho values to a site with the use of the new national geometric datum (NATRF2022) and the new geopotential datum (NAGVD2022?) will be discussed. Finally, a summary of near real-time methods will be presented as referenced in NGS guideline documents, highlighting the four cardinal rules for real-time positioning.

Presenter

William Henning, Prof.LS., is a Registered Professional Land Surveyor with over 49 years of active experience in all phases of the land surveying profession. He has been actively involved with education/outreach to the geospatial community for 23 years, presenting over 145 talks and workshops to geospatial professionals on surveying, mathematics and GNSS technology. Mr. Henning 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 trained various federal and local personnel in using GNSS equipment and correct positioning techniques. He has been the project lead for new height modernization geodetic networks in county-wide projects in the eastern U.S., where he planned, helped construct, processed, adjusted and managed new geodetic control systems using NGS guidelines. He has over 23 years experience working with various GNSS manufacturers’ real- time positioning systems. Mr. Henning is Past President of the American Association for Geodetic Surveying (AAGS) and is an ACSM/AAGS Fellow. He has been presented with the NOAA Administrator’s Award for outstanding accomplishment in producing real-time GNSS guidelines. As a geodesist at the NGS, he helped develop guidelines and support methodology for real-time GNSS positioning with state, national and international organizations. He is currently working as a consultant professional providing education workshops and other professional surveying services, and as a faculty member for Geo-Learn, Inc., where he is recording instructional videos for the use of surveyors, engineers and other geospatial professionals. Mr. Henning was awarded the Maryland Society of Surveyors “Surveyor of the Year” for 2013-14.
