Description:

The National Geodetic Survey (NGS) plans to modernized the National Spatial Reference System (NSRS) in 2025. One part of that modernization is the estimation of both geometric and orthometric reference epoch coordinates (RECs) from decades of existing GNSS, classical and leveling observations.
