Considerations on the further improvements of regional geoid modeling over the baltic countries

Abstract

is contribution reviews earlier geoid modeling research in the Baltic countries. e most commonly used modi cations of Stokes's formula are discussed. Similarities and di erences between stochastic and deterministic modi cation methods are outlined. Principles of selecting the geoid modeling methods and parameters are explained and numerically veri ed. e in uences of typical shortages of historic gravimetric datasets to geoid modeling are discussed. Suggestions for further data improvement and enhancements of other geoid modeling aspects are summarized.
