Abstract
A high-resolution and high-precision detailed gravimetric geoid has been computed for San Juan province in Argentina, ranging from 27 degrees S to 34 degrees S in latitude and 72 degrees W to 65 degrees W in longitude. The gravimetric geoid was calculated using the RTM method, a multiband spherical Stokes Fast Fourier Transformation, and the removerestore technique for the spherical harmonic reference field and the terrain. As an external evaluation, the gravimetric quasigeoid/geoid was compared to the geoid heights obtained from 90 GPS/levelling points available for the province. Finally, a GPS-tailored local geoid, which fits the GPS observations, was computed.
