Phrase: Hayford 1909 ellipsoid | Statement: [Bessel ellipsoid, comparedTo, Hayford 1909 ellipsoid]

Target entity: Hayford 1909 ellipsoid
Context triple: [Bessel ellipsoid, comparedTo, Hayford 1909 ellipsoid]

• A. 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.
• B. 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  The Bessel ellipsoid is a historical reference ellipsoid of the Earth defined in the 19th century for geodetic and cartographic purposes, particularly in Europe.
• C. 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.
• 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. National Geodetic Vertical Datum of 1929
  The National Geodetic Vertical Datum of 1929 is an older United States vertical reference system used to define elevations above sea level before being superseded by NAVD 88.
• F. None of above. chosen
• G. Unsure - the case is ambiguous/there is not enough information to decide.

Target entity: Hayford 1909 ellipsoid
Target entity description: The Hayford 1909 ellipsoid is a historical reference ellipsoid of the Earth, widely used in early 20th-century geodesy and mapping, particularly in Europe and North America, before being superseded by more modern global models.
