The Bessel ellipsoid refers to a specific mathematical model of the Earth's shape, which is used in geodesy and cartography. Named after the German mathematician and astronomer Friedrich Bessel, the Bessel ellipsoid is an oblate spheroid that approximates the shape of the Earth, particularly in relation to the geodetic surveys of the 19th century.
