High-Resolution Quasigeoid Model for Vietnam by bththam is a document available to read on EtoBox.
This study presents a high-resolution gravimetric quasigeoid model for Vietnam, developed using 29,121 land gravity measurements and additional fill-in data. The new model significantly improves accuracy over existing global models, achieving a standard deviation of 9.7 cm when compared to GNSS/levelling points, in contrast to the 19.2 cm and 29.1 cm deviations of EIGEN-6C4 and EGM2008, respectively. The methodology employed includes advanced techniques such as the Stokes integral and Least-Squares Collocat
