A Blueprint for 2022

In 2022, the entire National Spatial Reference System (NSRS) will be modernized. This document addresses the geometric aspects of the NSRS. Geometrically, the NSRS currently contains three reference frames (historically “horizontal datums”), known as NAD 83(2011), NAD 83(PA11) and NAD 83(MA11) which are used to define the geodetic latitudes, geodetic longitudes and ellipsoid heights of all points in the USA.
