Nad83 vs wgs84.

Any recent NAD83 (NSRS2007, 2011, probably CORS96 because it was used later than 1996 and possibly HARNs) versus WGS84/ITRF is now up to 1 m or more. Within NAD83, biggest jump was from original to the first HARN within a state. Some states have a 2nd or 3rd HARN / FBN adjustment which will be smaller.WGS84 frames are specifically named NAD83 (2011) and WGS84 (G1674). Thus, when the software tell us that the computed coordinates using GPS observations are referred to the WGS84, they actually mean WGS84 (G1674). On the other hand, if we use CORS coordinates data, or the OPUS service, the NAD83 reference frame to whichWGS84 and NAD83 are not, themselves projections, but coordinate systems differing by the datum (or 'representations of the spheroidal earth, defined mathematically') that they use. Imagine two points which have almost no horizontally spacing, but one very high up in the air and one close to the ground.EPSG:4979 is also based on the WGS84 ellipsoid, and differs from EPSG:4326 only in that it uses a 3D coordinate system, whereas 4326 uses a 2D coordinate system. Even geocentric coordinates (e.g. EPSG:4378) are based on an ellipsoid as they don't necessarily have the same centres.

The State Plane Coordinate System (SPCS), which is only used in the United States, is a plane coordinate system (north-south and east-west lines are perpendicular) in which each individual state has between one to six zones, depending on the state's size and shape. This coordinate system’s high level of accuracy is achieved through the use of relatively small …

(ITRF) and the World Geodetic System of 1984 (WGS84) Since 1990, the most accurate and stable reference frames available are the successive versions of the ITRF produced by the International Earth Rotation and Reference Systems Service (IERS). The ITRF is a … between NAD83 and the various ITRFs for use with the new realizations of WGS84, the bias between NAD83 and WGS84 was never acknowledged by the agency maintaining WGS84. Consequently, the vast majority of GPS receiver manufactures continue to treat NAD83 as being identical with the new realizations of WGS84 which results in position

Imagine two points which have almost no horizontally spacing, but one very high up in the air and one close to the ground. Datum is an older term. The concept of a datum is included within a geographic coordinate system. A geographic transformation is always defined in a particular direction, like from NAD 1927 to WGS 1984. Transformation names will reflect this: NAD_1927_To_WGS_1984_1. The name may also include a trailing number, as the above example has _1.

1. Is NAD83 the same as WGS84? NAD83 and WGS84 are not the same but they are related. NAD83 is a regional datum specific to North America, while WGS84 is a global datum. However, they share a similar underlying reference ellipsoid, which means that conversions between the two can be relatively straightforward. 2.
