| Abstract: | Differences between the heights, which are from control surveys of water level based on different reference surfaces, are discussed. Especially, the differences between heights from total station, GPS and levelling are analyzed theoretically and compared by the measured data. The methods of conversion from one kind of height to another are provided. |
