Abstract:

The tidal of East Sea is complex. In additional, the number of tide stations established by Vietnam not was enough to create the 3D TIN of Chart Datum. Therefore, the contents of this science are using mean sea level of global, mean sea level of local and local chart datum to calculating the 3D TIN of mean sea level and 3D TIN of sound datum. The tide data collected by the permanent tide stations ( Eg: Hon Dau tide station) and the tide data observed by Vietnam’s People Naval are using to calculator. The result of this science is supported tide data to create the navigation chart of sea areas not have tide observation
