摘要

摘要: 目的为实现局域水域垂直基准间的无缝转换,从深度基准面计算原理出发,根据潮波传播特征,提出了一种基于潮汐调和常数内插的无缝深度基准面建立方法,该方法较传统常用方法具有更高的精度和稳定性。通过长江口区域的实验验证了该方法的正确性及可行性,并在该区域建立了无缝深度基准面模型。

Abstract: Objective To establish a regional seamless chart datum and achieve seamless vertical datum conversion,thispaper starting from the datum calculation principle,and according to the tidal wave propagation characteristic,we propose a new method of constructing regional seamless chart datum based on the tidal harmonic constantsinterpolation.Firstly,the constants of unknown points in waters can be calculated by interpolation with usingthe known tide gauges.Secondly,we establish seamless chart datum based on these points with using a math-ematical model.When compared with the traditional geometric method,it significantly improves the construc-tion precision and overcomes the precision unstablity defect.Experiments in Yangtze Estuary were performed,and the results show that the method is correct and feasible.Finally,a seamless chart datum in Yangtze Estu-ary was established.
