WLIA 2025 Annual Conference Appleton

The National Geodetic Survey (NGS) is in the process of modernizing the National Spatial Reference System (NSRS), which is the common reference for geospatial data across the United States. NAD 83 and NAVD 88 will be replaced with the North American Terrestrial Reference Frame of 2022 (NATRF2022) and the North American-Pacific Geopotential Datum of 2022 (NAPGD2022). This presentation will outline the timelines for the implementation of the modernized NSRS, explain the building blocks of the new datums, address the practical implications for existing and new geospatial datasets, and look at the tools available from NGS that will help with the transition.
