1) valley line
山谷线
1.
Derivation of valley line and ridge line by segmental cubic polynomials;
利用分段三次多项式提取山谷线和山脊线
2.
In order to detect the spatial conflicts that rivers deviate from the valleys in the process of topographic database updating, a new algorithm using the vector projection method to quickly extract the valley lines related to the rivers is proposed.
针对数据更新中常见的河流偏离山谷线这一空间不一致问题,提出了一种基于矢量投影法的快速、准确地提取山谷点的方法,并利用提取出的山谷点来检查与其相关河流的空间关系的一致性;最后利用VB6。
3.
The usual method for extracting ridge line and valley line is based on geometric and physical character which is difficult to use the information hiding in the digital data.
针对当前山脊线和山谷线的提取都是从其几何特征或物理特征的单一方面进行研究和设计,不能够利用隐含在数字化资料中的山脊线和山谷线的有效信息的弊端;本文利用几何分析方法Douglas-Peuker提取山脊线和山谷线的特征点,并结合提取区域内地形概略的分水线和汇水线,用概略的分水线和汇水线对特征点进行识别、归类、顺序提取各条山脊线和山谷线,把山脊线的几何特性与物理特性结合起来,克服了各自的弊端。
