圆控制域的水深网分层构建方法

The Hierarchical Construction Method of Sounding Network Based on Circle Control Sphere

针对当前水深自动综合过程中无法形成合理网格的问题，本文提出了一种圆控制域的水深网分层构建方法。通过提取测量海域地形趋势线，设定水深网构造规则，根据不同情况下结点选择结果，实现水深网的分层构建。，实验结果表明，该方法在满足已有水深综合中网形要求的前提下，可以从海域整体地形特征入手，快速简捷地实现水深疏密分布，较好地提高了水深综合效率。

Since it is difficult to construct reasonable grid in current data automatic generalization process of sounding net- work, a hierarchical construction method of sounding network based on circle control sphere is presented in this paper. By extrac- ting the topographic trend line in measuring sea area, and setting the rules of sounding network construction, the hierarchical con- struction of sounding network is realized according to the node selecting results under different conditions. The experiment result indicates that the method will make the sounding network distribute reasonable easily and rapidly on the premise of satisfying the requirement of present comprehensive sounding network based on the topographic feature of the sea area, and it can also improve the sounding generalization efficiency.
