利用等高线数据提取山脊(谷)线算法研究

Research on the Algorithm of Extracting Ridge and Valley Lines Using Contour Data

  • 摘要: 在对现有的山脊线和山谷线自动提取算法进行分析比较的基础上,提出一种简单实用的自动提取山脊线和山谷线算法。实验结果表明,用本文方法所提取的山脊线和山谷线与实际地形相符合。

     

    Abstract: In this paper, the author put forwards an brief and practical arithmetic for auto extracting terrain lines from digital terrain data based on the analyzing and comparing of current arithmetic that auto extracting terrain lines from digital terrain data. At the end of this paper, the author gives an experiment result that shows that the ridge and valley extracted by the author's arithmetic is concord to the experimental terrain.
