GeoModel

GeoModel

is an option for GeoGraphics that specifies the reference body or model for it for the purposes of geodetic computations and map drawing.

Details

  • The following settings can be used:
  • Automaticuse the "ITRF00" datum for the Earth
    "datum"any of the datums in GeodesyData["Datum"]
    "ellipsoid"any of GeodesyData["ReferenceEllipsoid"]
    {a,b}an explicit ellipsoid with semiaxes ab
    ra sphere of radius r
    entitya planet or planetary moon Entity object
  • The semiaxes lengths a, b in GeoModel{a,b} and the radius r in GeoModelr can be given either as numbers in meters or Quantity lengths.
