| 摘 要： | 根据海洋测绘中垂直基准构建的需求,提出了一种基于主成分-逐步回归分析的建立局域无缝海图深度基准面的方法。在此基础上,利用中国某海区多个验潮站深度基准面值及分潮调和常数振幅,建立了该海区局域无缝深度基准面值回归方程。实例计算表明,该方法所建立的局域海区无缝海图深度基准面值能够达到厘米级精度,可为海图深度基准面体系的重新构建提供技术支持。

| Abstract: | In terms of the requirements on the vertical datum for hydrographic surveying and charting,a method of establishiy local seamless chart datum,based on the principal component-stepwise regression analysis,is presented in this paper.With the chart datum values and tidal harmonic constant information of tidal stations in a certain sea area of China the local seamless chart datum regression model of the sea areas with is established the new approach.The calculations by the model indicate that the accuracy of chart datum computed through the new method can achieve the centimeter level,which can be used for the establishment of high precision chart datum. |
