In 2022, the National Geodetic Survey (NGS) will be replacing the US horizontal and vertical datums (NAD 83 and NAVD 88).  This talk will highlight the major changes and discuss impacts to the geospatial community to include the concept of time dependent coordinates and activities that are being undertaken to ensure a smooth transition to include new State Plane Coordinates.
