National Spatial Reference System
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 National CORS (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.[1]
In 2022, the NSRS will be modernized and use the following four frames of reference:[2]
- 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)
