| Abstract: | This paper introduces the features of the water depth of marine surveying and mapping and the reason of correction of water level. The prerequisite for correction of water level and the principle using time difference method, calculation of tidal station similarity coefficient and the tidal difference iterative method for solving fixed point, water level correction. Application of example shows that time difference method of water level can be widely used in the same basic property of tide waters . |
