Terrain effects on geoid determination.
Bajracharya, Sujan.

Terrain effects on geoid determination. - 114 p.

Adviser: M. G. Sideris.

Thesis (M.Sc.)--University of Calgary (Canada), 2003.

Gravimetric reduction schemes play an important role on precise geoid determination, especially in rugged areas. The main theme of this research is to explore different gravimetric reduction schemes in the context of precise geoid determination, in addition to the usual Helmert's second method of condensation and residual terrain model (RTM). A numerical investigation is carried out in the rugged area of the Canadian Rockies to study gravimetric geoid solutions based on the Rudzki inversion scheme, Helmert's second method of condensation, RTM, and the topographic-isostatic reduction methods of Airy-Heiskanen (AH) and Pratt-Hayford (PH). The mathematical formulations of each of these techniques are presented.
