WGS84 (World Geodetic System 1984) och NAD83 (North American Datum 1983) är båda geodetiska koordinatsystem som används för att definiera positioner på jordens yta. WGS84 är ett globalt koordinatsystem som ofta används inom GPS och satellitbaserad navigering. NAD83 är ett regionalt koordinatsystem som används i Nordamerika för mätning och kartläggning.

While NAD83 and WGS84 may seem similar, there are some subtle differences between them. In most mapping, exploration, and GIS applications, coordinates in NAD83 and WGS84 will be practically identical. However, it is essential to note that these coordinates may differ by a few centimeters due to variations in the reference ellipsoid …

Ellipsoid heights NAD83 vs. ITRF00 - Defined origins are best estimate of the center of mass; NAD83 is not geocentric. Move origin; move ellipsoid surface as indicated by scale shown on map. Ellipsoid height differences reflect the non-geocentricity of NAD83. The original WGS 84 realization essentially agrees with NAD 83 (1986). It is generally assumed, and this assumption is substantiated by the National Geodetic Survey, that WGS 84 (original) is identical to NAD 83 (1986).
