基于等高线提取地形特征线的研究

Extracting Topographic Characteristic Line from Contours

  • 摘要: 借助约束Delaunay三角网,研究了两种从等高线数据提取地形特征线的方法。给出了两种方法的实现过程,讨论了实验结果的异同,并分析了存在差异的原因。

     

    Abstract: Two kinds of methods on extracting topographic characteristic lines from contours are presented,by means of constrained Delaunay TIN,and their computing processes are given.Based on these methods,similarity and difference of the experimental results is discussed,and the reason resulting in these differences is analyzed.
