WebNAD83 moves at about 2.5 cm/y relative to the ITRF/WGS84 systems. They also use different ellipsoid models (NAD83: GRS80 vs. WGS84: WGS84) – but the ellipsoids are very similar and this doesn’t cause any meaningful differences. Transforming between NAD83 and WGS84 typically isn’t recommended for most applications because standard WebThe result was a new realization of the NAD 83 horizontal datum NAD 83 (2011).
