What Is The Difference Between Ellipsoid Height And Elevation?

WebThe height of the geoid above the ellipsoid, N, is sometimes called the geoid undulation. It can be used to convert a height above the ellipsoid, h, to the corresponding height above the geoid (the orthometric height, roughly the height above mean sea level), H, using the relations h = N + H; H = −N + h. WebEllipsoidal height (or ellipsoidal altitude), also known as geodetic height (or geodetic altitude), is the distance between the point of interest and the ellipsoid surface, … WebEllipsoid height (h) is the difference between the ellipsoid and a point on the Earth's surface. It is also called the geodetic height. When a GPS receiver measures elevation data, it is referenced to the ellipsoid.
