Topic Summary: Change. Most people don’t like it, but some changes are needed to make the world a better place. Such a time is nearly upon us: in 2022 or shortly after, the National Geodetic Survey (NGS) will modernize the National Spatial Reference System (NSRS). Since the NSRS is the basis for all civilian positioning in the U.S., modernizing it will profoundly affect surveying, engineering, and GIS. The modernization includes replacing the existing datums with terrestrial reference frames and a geopotential (“vertical”) datum; development of a new State Plane Coordinate System; and managing spatial data in a way that takes into account the fact that the Earth itself is dynamic. But that’s not all. The end of 2022 will also see the end of the U.S. survey foot, and its nationwide replacement by a single foot definition (identical to the “international” foot). This seminar gives an overview of the impending new datums and state plane coordinate system changes. The seminar will close with a discussion of the depreciation of the U.S. Survey Foot.

The presentation will introduce changes to the National Spatial Reference System (NSRS) including details on the horizontal/geometric datum and geopotential/vertical datums coming in 2022. We will also discuss related State Plane Coordinate System updates for 2022 and the depreciation of the U.S. Survey foot.

32 year career at the National Geodetic Survey. In Late 2016 I became the NGS Mid Atlantic Regional Advisor. The region spans coastal states Delaware south to Georgia and Puerto Rico and US Virgin Islands. Previously,(2005-2016) served as the NGS NC State Advisor , 1986-2005 part of the NGS Survey teams participating in Leveling, GPS surveys, and Airport Charting. Undergrad was at North Dakota State University in Electrical Engineering and Music Education. Additional undergrad studies in Geomatics at the Oregon Institute of Technology. GIS Certificate from Penn State University.
