The traditional, orthometric height (H) is the height above an imaginary surface called the geoid, which is determined by the earth's gravity and approximated by MSL. ... MSL is defined as the zero elevation for a local area. The zero surface referenced by elevation is called a vertical datum.
What is the difference between ellipsoid height and elevation?
Because the earth geoid is set a the level of the average sea level it is often called the elevation at Mean Sea Level (MSL). The Ellipsoidal Height of that same point of the Earth Surface is the vertical distance from that point to the ellipsoid (ochre surface in the illustration).
What is the difference between orthometric height and ellipsoidal height?
The orthometric (geoid) height of a point of the Earth Surface is the distance Ho from the point to the geoid. The ellipsoidal height of a point of the Earth Surface is the distance He from the point to the ellipsoid.
