1) Fire proof belt of ridge
山脊防火线
2) Firebreak tree belt in the ridge of a mountain
山脊防火林带
3) ridge line
山脊线
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.
A ridge line extraction algorithm is proposed based on DEM according to the characteristic of the terrain,firstly,the algorithm fills depressions and smoothes the terrain efficiently,then extracts the ridge line and thins it,lastly,the main ridge line is extracted to meet the requirement of the occlusion culling.
针对大规模复杂地形的特点,提出了一种有效的基于规则网格的地形主山脊线特征提取算法。
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。

Automatic extraction for ridge and valley by vertical sectional method;
垂直剖面法自动提取山脊线和山谷线
2.
Extraction of ridge and valley from DEM based on conjugate terrain;
基于共轭地表曲面的山脊线和山谷线提取方法的研究
3.
The authors put forwards a new method which select the terrain profile perpendicular to falling line (opposite direction of gradient) to determine the candidate points on ridge and valley.
提出了一种基于地形梯度方向的山脊线和山谷线的提取方法,该方法从理论上进一步完善了地形高程断面极值法。
