  • A. WGS84 chosen
    WGS84 is the global geodetic reference system and standard coordinate framework used for GPS and most modern mapping applications.
  • B. GRS80
    GRS80 is a geodetic reference ellipsoid defined in 1980 that serves as a standard mathematical model of the Earth's shape for modern mapping and surveying systems.
  • C. Bessel ellipsoid
    The Bessel ellipsoid is a historical reference ellipsoid of the Earth defined in the 19th century for geodetic and cartographic purposes, particularly in Europe.
  • D. Airy Modified ellipsoid
    The Airy Modified ellipsoid is a slightly adjusted version of the Airy ellipsoid used as the reference surface for mapping and geodetic calculations in systems such as the Irish grid reference system.
  • E. Airy 1830 ellipsoid
    The Airy 1830 ellipsoid is a reference ellipsoid defined in the 19th century for geodetic calculations in Great Britain, forming the basis of traditional mapping systems such as the British National Grid.
