  2. North American Datum - Wikipedia

    en.wikipedia.org/wiki/North_American_Datum

    One well-known difference is the placement of the center of the Earth, with the two systems differing by about 2.2 metres (7.2 ft). [14] In addition, NAD 83 is defined to remain constant over time for points on the North American Plate, whereas WGS 84 is defined with respect to the average of stations all over the world. Thus the two systems ...

  3. National Spatial Reference System - Wikipedia

    en.wikipedia.org/wiki/National_Spatial_Reference...

    The NSRS consists of a National Shoreline, the NOAA CORS Network [2] (a system of Global Positioning System Continuously Operating Reference Stations), a network of permanently marked points, and a set of models that describe dynamic geophysical processes affecting spatial measurements. The system is based on the datums NAD 83 and NAVD 88. [3]

  4. International Terrestrial Reference System and Frame

    On 7 January 2024 move to IGS20 happened, so WGS 84 is now aligned with ITRF2020, including PSD (post-seismic deformation), also called G2296. On the other hand GLONASS is using PZ-90.11, which is close to ITRF2008 at epoch 2011.0 and is using 2010.0 epoch (that means when you use reference transformation to PZ-90.11 you will get January 2010 ...

  6. World Geodetic System - Wikipedia

    en.wikipedia.org/wiki/World_Geodetic_System

    The WGS 84 datum surface is an oblate spheroid with equatorial radius a = 6 378 137 m at the equator and flattening f = 1 ⁄ 298.257 223 563. The refined value of the WGS 84 gravitational constant (mass of Earth's atmosphere included) is GM = 3.986 004 418 × 10 14 m 3 /s 2. The angular velocity of the Earth is defined to be ω = 72.921 15 × ...

  7. Geodetic datum - Wikipedia

    en.wikipedia.org/wiki/Geodetic_datum

    The WGS 84 datum, within two meters of the NAD 83 datum used in North America, is the only world referencing system in place today. WGS 84 is the default standard datum for coordinates stored in recreational and commercial GPS units. Users of GPS are cautioned that they must always check the datum of the maps they are using.

  8. Geodetic Reference System 1980 - Wikipedia

    en.wikipedia.org/wiki/Geodetic_Reference_System_1980

    [1] [2] [3] The GRS80 gravity model has been followed by the newer more accurate Earth Gravitational Models, but the GRS80 reference ellipsoid is still the most accurate in use for coordinate reference systems, e.g. for the international ITRS, the European ETRS89 and (with a 0,1 mm rounding error) for WGS 84 used for the American Global ...

  9. Projected coordinate system - Wikipedia

    en.wikipedia.org/wiki/Projected_coordinate_system

    Each projected coordinate system, such as "Universal Transverse Mercator WGS 84 Zone 26N," is defined by a choice of map projection (with specific parameters), a choice of geodetic datum to bind the coordinate system to real locations on the earth, an origin point, and a choice of unit of measure.
