Brave New Coordinates, Coming Soon to a Geodatabase Near You

Presenters: Michael Dennis, Brian Fisher, Jack Avis

Fundamental changes are coming soon to the coordinate systems used for spatial data in the United States.  Within the next few years, NOAA’s National Geodetic Survey (NGS) will modernize the National Spatial Reference System (NSRS).  The NSRS is the basis for civilian positioning in the U.S., and the coming changes will have a profound impact on GIS and the geospatial professions.  NGS defines, maintains, and provides access to the NSRS, but the NSRS is not static. It must evolve as both positioning technology and our understanding of the Earth continually improve.  This presentation gives an overview of the coming changes, including replacement of the current U.S. horizontal and vertical datums with dynamic terrestrial reference frames and a gravity-based geopotential datum.  Existing State Plane Coordinates will also be superseded by the State Plane Coordinate System of 2022 (SPCS2022).  An update will be provided on the status of SPCS2022, including development of a three-layer system for Arizona consisting of a statewide layer designed by NGS and two multiple-zone layers designed by state stakeholders. This will be an hour well spent learning about the brave new coordinates that will soon define the spatial data infrastructure in Arizona, and the nation.

Takeaway: Learn about how the coordinate systems you use now will soon change, with a focus on new State Plane coordinates in Arizona.

Who should attend: Anyone who will author, consume, share, or perform analyses using geospatial data in Arizona within the next few years and beyond.
