What is the relationship between geoid and ellipsoid?
What is the relationship between geoid and ellipsoid? This difference is known as the "geoid height." The differences between the ellipsoid and geoid can be significant, as the ellipsoid is merely a baseline for measuring topographic elevation. It assumes that the Earth's surface is smooth, where the geoid does not. What is the difference between an ellipsoid and a geoid? The geoid surface is irregular, unlike the reference ellipsoid (which is a mathematical idealized representation of the physical Earth as an ellipsoid), but is considerably smoother than Earth's physical surface. How is geoid height calculated? To find ellipsoidal height at...
