Orthometric vs ellipsoidal height

Follow

This article explains the difference between orthometirc (geoid) 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.

The geoid height above the ellipsoid (N) is the difference between the ellipsoidal height and orthometric (geoid) height.

N = He  Ho

Where:

N = geoid height above the ellipsoid
He = ellipsoidal height
Ho = orthometric (geoid) height
