WebAn ellipsoid is a 3D geometric figure that has an elliptical shape. It can be viewed as a stretched sphere. An ellipsoid gets its name from an ellipse. Any plane that cuts through an ellipsoid forms an ellipse. Two ellipsoids are shown in the figure below. Real life examples of an ellipsoid include an egg or a blimp. Ellipsoid equation WebMay 26, 2024 · Contrary to some descriptions, the earth is not a sphere, nor is it a spheroid, nor is it an ellipsoid. These approximations can be useful, but in reality the earth is its own crazy wonky lumpy shape that is constantly changing in four dimensions with mass movements and human behavior.

WebSep 14, 2010 · Since the Earth is flattened at the poles and bulging at the equator, the geometrical figure used in geodesy to most nearly approximate Earth's shape is an oblate spheroid. An oblate spheroid, or oblate ellipsoid, is an ellipsoid of revolutionobtained by rotating an ellipse about its shorter axis. WebJan 1, 2014 · A reference ellipsoid can be interpreted as the mathematical shape of the Earth, and a normal ellipsoid is the mathematical and physical shape of the Earth. The reference ellipsoid or normal ellipsoid is a close approximation of the geoid. Therefore, the shape of the Earth studied in geodesy primarily refers to the shape of the geoid.

WebApr 6, 2024 · The ellipsoid shape formed is by revolving an ellipse around one of its axes. If m and n are greater than o, the spheroid will be oblate; if lesser, the surface will be a prolate spheroid. Having said that, If m, n and o are the principal semiaxes, a standard equation of such an ellipsoid is x²/m² + y²/n² + z²/o² = 1.
