Geoid height of new global gravity field models on 3D globe ("Earth potato")
"A geoid is a three dimensional surface of equal gravity which is perpendicular to the direction of the gravity vector at all points. Since the mass distribution of the Earth is not uniform and the direction of gravity changes accordingly, the resultant shape of the geoid is irregular. Although there are an infinite number of these equipotential surfaces for the Earth, the term 'geoid' is often used to describe the equipotential surface which best corresponds with mean sea level."
