National Spatial Reference System
Template:Short description Template:DMCA Template:DMCA
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[3] (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 the datums NAD 83 and NAVD 88.[4]

The North American-Pacific Geopotential Datum of 2022 (NAPGD2022) is a geodetic datum set produced by the U.S. National Geodetic Survey to improve the National Spatial Reference System (NSRS).[5][6][7] It will replace 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] In association with this release, a new, time-dependent geoid model, GEOID2022, will also be released.[9] The release date for these models was planned for 2022 but they have been delayed.
