4PDH- The session will start with an overview of the many Products and Services that NGS provides to the geospatial community and will move into a discussion of NSRS Modernization, which is the blanket term for our forthcoming new datums and other improvements to our Nation’s geodetic infrastructure.  For those that have not already heard, NATRF2022 will replace NAD83, NAPGD2022 will replace NAVD88, and SPCS2022 will replace SPCS83.  Specific details such as: what will be different about the geometric Reference Frame as compared to NAD83, what it means to be working in a Geopotential Datum, new terminology that will be used in the modernized system, the deprecation of the US Survey Foot, and some ways to prepare will be presented.  This same session will be presented Thursday afternoon and Saturday morning.
