| Domain | Definition |
Aerospace | An ellipsoid; a figure resembling a sphere. Also called ellipsoid or ellipsoid of revolution from the fact that it can be formed by revolving an ellipse about one of its axes. If the shorter axis is used as the axis of revolution, an oblate spheroid results, and if the longer axis is used, a prolate spheroid results. The earth is approximately an oblate spheroid. (references) |
Geography | A solid body formed by the revolution of an ellipse about its axis. Source: European Union. (references) |
Geological | Mathematical figure closely approaching the geoid in form and size and used as a surface of reference for geodetic surveys. A reference spheroid or ellipsoid is a spheroid determined by revolving an ellipse about its shorter (polar) axis and used as a base for geodetic surveys of a large section of the Earth (such as the Clarke spheroid of 1866 which is used for geodetic surveys in the United States).

Metallurgy | A small sphere. Source: European Union. (references) |
Mining | In general, any figure differing but little from a sphere. In geodesy, a mathematical figure closely approaching the geoid in form and size, andused as a surface of reference for geodetic surveys. (references) |
