Abstract

This scientific article assessed accuracy of a local gravimatric quasigeoid model created from the EGM2008 and transfered to the quasigeoid Hon Dau. Comparing to local GPS/leveling quasigeoid created from 185 GPS/leveling height anomalies on 185 first order vertical benchmarks, standard deviation of the local gravimatric quasigeoid is ± 8,5 cm, differences between GPS/leveling and gravimetric height anomalies are in the range between - 0,224 m and 0,236 m.
