NAD 83 was computed by the geodetic agencies of Canada (Federal and Provincial) and the National Geodetic Survey for several reasons.realization of NAD83 fixed to the North American tectonic plate. 2. Problems At the time of its initial realization, NAD83 was intended to be a geocentric system and was compatible with the other geocentric systems of the time, such as the original realization of WGS84. However, due to the use of more accurate techniques, it is now known thatGRS80 / WGS84 (NAD83) Airy 1858 Airy Modified Australian National Bessel 1841 Clark 1880 Everest 1830 Everest Modified Fisher 1960 ... WGS 72 User defined. Please note that the GRS80 and WGS84 are considered to be the same. Actually, there is a very small difference in the flattening which results in the semi-minor axis, b, being different by 0 ...Originally, the difference between WGS84 as originally rolled out in 1987 and NAD83 as first introduced in 1986 coordinates was so small that transformation was unnecessary. That is no longer the case when it comes to NAD83 2011 (2010.0) and WGS84 (G1762) the difference can be ~1 to 2 meters.

4. The NAD 27 and the NAD 83 are different in their ellipsoids. 5. When talking about accuracy, it has been said that the North American Datum of 1983 is more accurate than the North American Datum of 1927. 6. The NAD 83 uses modern technology; the NDA 27 has been done only manually. Author.The North American Datum of 1983 (NAD83) is the most current datum in North America. It provides latitude and longitude and some height information using the reference ellipsoid GRS80. NAD83 corrects some of the distortions from NAD27 over distance by using a more dense set of positions from terrestrial and Doppler satellite data.
