• GeodesyRelated: It expresses elevation relative to a gravity-defined surface rather than an ellipsoid.

• GeoidRelated: It is the standard physical elevation that geoid models help derive from satellite heights.

• Vertical datumRelated: This common elevation type is measured from a geoid-based vertical reference.

• Figure of the EarthRelated: It expresses elevation relative to a gravity-based representation of Earth’s figure.

• Physical geodesyRelated: It expresses elevation relative to the gravity-defined surface rather than an ellipsoid.
