Abstract: This paper describes the basic theory, assumptions and approximations behind the computation of the Canadian GSD95 geoid model. It discusses the remove-restore approach and describes Helmert’s second condensation method. This latter topic shows the sequence of the gravity reductions to be applied to the surface gravity measurements in order to comply with the Stokes theory. It introduces a series of approximations to the Stokes theory in order to evaluate the geoid in a practical way. Finally, it discusses the comparison between the GSD95 geoid model and GPS-levelling data.
