Abstract
This paper focuses on studying logn distance transference of height datum across seas by combining ellipsoidal height derived from GPS with gravimetric geoid height. The Yellow Sea Height Datum is transferred to Yangshan Island which is 30 km away from Luchaogang in Shanghai. The stations heights derived in this way are compared with those determined from two independent sets of the tidal observations taken in two years, and the difference values are 1.0 cm and 6.0 cm, respectively. Moreover, the derived height differences between two sections on the island are also compared with the values derived from precise leveling with respect to the same section. The result shows that the inconsistencies are only 0.2 cm and 0.7 cm, respectively.
