National Spatial Reference System
 | It has been suggested that Datum of 2022 be merged into this article. (Discuss) Proposed since January 2022. |
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. Pre-2022, the system is based on NAD 83 and NAVD 88.[2]
In 2022, 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]
