2026 Big Sky GeoCon - From Data to Design

NOAA's National Geodetic Survey (NGS) defines, maintains, and provides access to the National Spatial Reference System (NSRS), which is a common foundation for geospatial data that serves as the basis for civilian surveying and mapping in the United States. Changes in technology and a better understanding of the dynamic earth have made it necessary to improve the NSRS to be of better use for modern applications. Currently, NGS is in the process of modernizing the NSRS, updating the existing horizontal datums with a suite of geometric reference frames and the vertical datums with a gravimetrically-derived geopotential datum.
