WebA new pair of geodetic datums are set to be produced by NOAA’s National Geodetic Survey (NGS). These datums will modernize the National Spatial Reference System (NSRS) by replacing the North American Datum of 1983 (NAD 83) and the North American Vertical Datum of 1988 (NAVD 88). WebTwo of the datums that make up the NSRS, the North American Datum of 1983 (NAD 83) and the North American Vertical Datum of 1988 (NAVD 88), were created with old survey techniques that aren’t incredibly reliable or relevant with the advent of GNSS.
