National Spatial Reference System

October 27, 2023

The National Spatial Reference System (NSRS), managed by the National Geodetic Survey (NGS), is a coordinate system that includes latitude, longitude, elevation, and other values. The NSRS consists of a National Shoreline, the NOAA CORS Network[1] (a system of Global Positioning System Continuously Operating Reference Stations), a network of permanently marked points, and a set of models that describe dynamic geophysical processes affecting spatial measurements. The system is based on NAD 83 and NAVD 88.[2]

In 2024 or 2025,[needs update] the NSRS will be modernized with a focus on GNSS and geoid use. It will use the following four frames of reference, each representing a tectonic plate:[3][4]

  • North American Terrestrial Reference Frame of 2022 (NATRF2022)
  • Pacific Terrestrial Reference Frame of 2022 (PTRF2022)
  • Caribbean Terrestrial Reference Frame of 2022 (CTRF2022)
  • Mariana Terrestrial Reference Frame of 2022 (MTRF2022)
    A (relatively prominent) survey monument that is part of the NSRS[5]

Datum of 2022 edit

The Datum of 2022 is a placeholder name for a new geodetic datum set to be produced by the U.S. National Geodetic Survey in 2024–2025[6][7] to improve the National Spatial Reference System (NSRS) by replacing the North American Datum of 1983 (NAD 83) and the North American Vertical Datum of 1988 (NAVD 88) with a new geometric reference frame and geopotential datum.[8]

The new reference frames will rely primarily on Global Navigation Satellite Systems (GNSS), such as the Global Positioning System (GPS), as well as on a gravimetric geoid model resulting from NGS' Gravity for the Redefinition of the American Vertical Datum (GRAV-D) Project.

These new reference frames are intended be easier to access and to maintain than NAD 83 and NAVD 88, which rely on physical survey marks that deteriorate over time.[8]
