How To: Determine which NAD_1983_To_WGS_1984
Jul 17, 2019 · Summary. When originally defined, North American Datum 1983 (NAD 1983) and World Geodetic System 1984 (WGS 1984) were equivalent. In order to minimize coordinate changes, NAD 1983 is tied to the North American, Pacific (for Hawaii, Guam, etc.), and Marianas tectonic plates. WGS 1984 is tied to the International Terrestrial Reference System (ITRF) which is independent of the tectonic plates.
