The Ongoing Modernization of the National Spatial Reference System
The mission of NOAA’s National Geodetic Survey (NGS) is “to define, maintain and provide access to the National Spatial Reference System (NSRS) to meet our nation's economic, social, and environmental needs." NSRS is the system of latitude, longitude, elevation, and related models and tools, which comprise the nation’s foundational positioning infrastructure. NGS has for several years been developing – and promoting – the ongoing modernization and evolution of NSRS, toward the 2022 goal of replacing the North American Datum of 1983 (NAD83) and the North American Vertical Datum of 1988 (NAVD88). The new positioning paradigm will impact all users of geospatial data, either directly or indirectly, and an understanding of the whats, whys, hows, and whens of this effort will ease your transition. This presentation will update you on today’s status of the NSRS modernization and help you prepare for 2022.
