On the Consistency between a Classical Definition of the Geoid-to-Quasigeoid Separation and Helmert Orthometric Heights [PDF]
Sensors, 2023 It is acknowledged that a classical definition of the geoid-to-quasigeoid separation as a function of the simple planar Bouguer gravity anomaly is compatible with Helmert’s definition of orthometric heights.

Discussion on the orthometric height realization
Geodesy and Cartography, 2012 In the theory of the orthometric height, the mean value of gravity along the plumbline between the geoid and the earth's surface is defined as the integral mean. To determine the mean gravity from the gravity observations realized at the physical surface

On the geoid and orthometric height vs. quasigeoid and normal height [PDF]
Journal of Geodetic Science, 2018 The geoid, but not the quasigeoid, is an equipotential surface in the Earth’s gravity field that can serve both as a geodetic datum and a reference surface in geophysics. It is also a natural zero-level surface, as it agrees with the undisturbed mean sea

ACCURACY ASSESSMENT OF DIFFERENT POLYNOMIAL GEOID MODELS IN ORTHOMETRIC HEIGHT DETERMINATION FOR AKURE, NIGERIA [PDF]
Geodetski Glasnik, 2021 Height is an important component in three dimensional coordinates and determination of the position of points for any meaningful development. Ellipsoidal heights from GNSS require geoid model which could be global, regional and local for transformation ...

Journal of Geodetic Science, 2023 The use of orthometric height in geodetic applications provides elevations on the physical topographic surface of the earth rather than ellipsoidal heights that are not in conformity with the physical topography. Global positioning system (GPS)/levelling
