What are NAD83 coordinates?

NAD83 is an acronym for North American Datum of 1983, a geocentric datum and geographic coordinate system based on the 1980 Geodetic Reference System ellipsoid (GRS80). Mainly used in North America, its measurements are obtained from both terrestrial and satellite data.

Is Google Maps in NAD83?

For FM and LPFM radio stations, the FCC uses an older coordinate system called NAD27 whereas most coordinates including Google Maps coordinates, use the newer NAD83 system.

What projection is NAD83?

UTM NAD83 is a projected coordinate system that represents physical locations abstracted to a flat, cartesian coordinate system. The UTM NAD83 projection uses the GRS80 ellipsoid and a center-of-the-earth anchor point as its datum, both of which are slightly different than the WGS datum.

Is Google Earth NAD83 or NAD27?

Where does the NAD83 coordinate system come from?

NAD83 is an acronym for North American Datum of 1983, a geocentric datum and geographic coordinate system based on the 1980 Geodetic Reference System ellipsoid (GRS80). Mainly used in North America, its measurements are obtained from both terrestrial and satellite data.

What is the North American Datum of 1983 coordinates?

Geographic coordinates provided to the Commission via the Universal Licensing System must be referenced to the North American Datum of 1983 (NAD83). If the source from which you obtain the coordinates is referenced to another datum (e.g., NAD27, PRD40) you must convert the coordinates to NAD83.

Is the NAD83 datum still on the same datum?

Since then, the increasing accuracy and availability of GPS has required two adjustments of the entire network. These adjustments produced new realizations that are still on the same datum: NAD83 (NSRS2007), and NAD83 (2011). What realization of NAD 83 should I use?

Can a NAD27 point be displaced from a NAD83 point?

A point having a given latitude and longitude in NAD27 may be displaced on the order of many tens of meters from another point having the identical latitude and longitude in NAD83, so it is important to specify the datum along with the coordinates.
