Speakers and Course Descriptions

Session 2 on Wednesday Morning: Denis Riordan

Outline of National Geodetic Survey (NGS) Presentations for the Alabama Society of Professional Land Surveyors 2019 Fall Conference in Pelham, AL.

Presentation 1

Title:  Progress toward 2022 and the New Datums

Time:  1.5 hours

The mission of NOAA’s National Geodetic Survey (NGS) is "to define, maintain and provide access to the National Spatial Reference System (NSRS)."  The NSRS is the nation's system of latitude, longitude, height (geometric and orthometric), and the related geophysical and geodetic models and tools, which provides a consistent spatial reference framework for the nation.  Preparations are underway by NGS for a comprehensive NSRS makeover that will determine and publish a new generation of horizontal and vertical datums in 2022.  This presentation will give an update on NGS’ preparations and progress as we move closer to the actual release date for the new datums.

Presentation 2

Title:  The NGS State Plane Coordinate System 2022 (SPCS2022) Project

Time:  1.0 hour

In conjunction with the new geometric datum to replace the North American Datum of 1983 (NAD83), NGS is working to update the state plane coordinate system for each of the U.S. states.  The State Plane Coordinate System 2022 (SPCS2022) project is an opportunity for each state to make changes and or updates to the existing NAD83 state plane coordinate system.  This presentation will talk about the SPCS2022 project, how it will apply to all states, and proposed changes for Alabama.

Presentation 3

Title:  The NGS 2022 Transformation Tool Campaign

Time:  1.0 hour

Presentation Overview:  As we move toward new U.S. datums, NGS will developed a vertical transformation model to go from the existing NAVD88 vertical datum to the new geopotential reference surface, NAPGD2022.  This presentation will talk about the ongoing NGS GPS on Bench Mark project, which is being used to acquire updated GPS observation data on published bench marks for the purpose of building the vertical transformation model for 2022. 

Session 4 on Wednesday Afternoon, & Session 8 on Thursday Afternoon: Dr. Bill Hazelton

Dr. Bill Hazelton is an Associate Professor at Troy University in the Geospatial Informatics Department. He has previously taught at a number of other higher-educational institutions in the US and Australia. He has been a licensed surveyor since 1985, worked in Antarctica for a year as a glaciologist, run a number of businesses, and has surveyed on three continents. Bill is a past president of the Surveying and Geomatics Educators Society and was a director of ASPRS.
