WebJul 12, 2024 · ( Geodetic Glossary, pp. 57) The North American Datum of 1983 (NAD 83) is the horizontal control datum for the United States, Canada, Mexico, and Central America, based on a geocentric origin and the Geodetic Reference System 1980. This datum, NAD 83, is the current geodetic reference system. WebVertical datums are used as a reference against which to base height measurements in order to know that all measurements start from the same “zero” and can therefore be compared. NOAA’s National Geodetic Survey has been in the business of establishing national vertical datums throughout the history of the organization. Introduction
