| 摘 要： | 地性线是非常重要的地形结构信息,应用领域十分广阔。采用单纯的矢量方法提取的地性线往往不连续,比较零碎。阐述了利用数学形态学的流域分割算法提取地性线的原理,介绍了基于等高线,采用矢量栅格混合算法提取地性线的具体步骤,最后,给出了结论,实验结果表明,采用本文提出的算法是可行的,提取的地性线有较好的连续性。

| Abstract: | Terrain line is a sort of important terrain structure data and it is widely applied.Terrain line traced with only vector method is not continuous.In this paper,the author discusses the principle of tracing terrain line adopting valley segmentation method of mathematical morphology,and introduces the tracing process with vector-grid admixture method.At the end of the paper,the author draws a conclusion.Test results show that the method is feasible and continuous terrain line is got. |
