A discussion on the approximations made in the practical implementation of the remove–compute–restore technique in regional geoid modelling
LE Sjöberg - Journal of Geodesy, 2005 - Springer
The remove-compute-restore (RCR) technique is the most well known method for regional
gravimetric geoid determination today. Its basic theory is the first-order approximation of
either Molodensky's method for quasi-geoid determination or the classical geoid modelling
by Helmert's second method of condensing the topography onto the geoid. Although the
basic approximate formulae do not meet today's demands for a 1-cm geoid, it is sometimes
assumed that the removal of the less precise long-wavelength terrestrial gravity anomaly …
