The National Geodetic Survey is modernizing the National Spatial Reference System (NSRS) with new datums to replace NAD83 and NAVD88. In this webinar Jeff will introduce the North American Terrestrial Reference Frame of 2022 (NATRF2022) and discuss similarities and differences as compared to the current NSRS geometric datum, NAD83. He will explain the concepts behind NATRF2022 development and provide details on future NGS database/datasheet terminology.  The modernization effort also includes a re-design of the SPCS, which will be briefly covered as there is a direct relationship between SPCS coordinates and the geodetic datum they are based on.
