基于等高线簇的沟谷线提取算法的研究与实现
|
摘要
从数字化地形资料中自动提取沟谷线的技术在水文分析、工程领域等具有重要的意义。在对现有的沟谷线自动提取的基础上,提出一种简单准确的沟谷线提取的方法。选取某一区域的矢量地形图进行试验与实际地形进行对比,结果表明沟谷线提取方法是准确的。
It is the important meaning of the technology of auto-extraction valleys line from numerical topographic data for hydro-geological analysis,engineering area and etc. The article is based on auto-extraction of the present valleys line and put forwards a simple and accurate method for auto-extraction valleys line. To select the topographic map of a region for testing and to compare to the actual terrain,the result show the method is correct.
