Course Availability

This course is only available to trainees 365 days after purchase. It would need to be repurchased by the trainee if not completed in the allotted time period. This course is no longer available. You will need to repurchase if you wish to take the course again.

Description

Geospatial practitioners are familiar with using active stations to remotely provide control data to produce high precision horizontal positions. However, when our new national vertical (geopotential) datum is rolled out around 2022, we will also be able to remotely access active stations for high precision orthometric heights. This session will explain the new national geometric and geopotential datums in comparison to NAD 83 and NAVD 88 and underline the transition from passive monuments in the ground to active antennas in the air as the basis for our vertical “truth”. Additionally, the different heights, such as ellipsoidal, orthometric, dynamic and geoid, found on a typical NGS data sheet, will be explained with the role that gravity plays for each (or not).

Objectives

Objectives
To become familiar with these terms, how they interrelate and their expected precisions & accuracies:
• Ellipsoid heights
• Orthometric heights
• Geoid heights
• Dynamic heights
• Geopotential numbers
• National vertical datums

He has been actively involved with education/outreach to the geospatial community for almost 20 years, presenting over 100 talks and workshops on surveying 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 editing 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. 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.
