The application of Stokes’ formula to create geoid undulation requires no masses outside the geoid. Usually, a constant density of 2.67g / cm3 is used in the determination of the geoid which introduces error in the reduced gravity anomalies (Helmert’s condensation) and consequently the geoid. In thi...
