基于独立自封闭等高面的山顶点自动提取
Automatic Extraction Method of Peak Point Based on Self-sealing Contour Surface
【摘要】 基于GIS提取独立自封闭等高面,判断区域内高程最大值的位置,实现山顶点的自动提取。实验表明该方法操作简便、结果准确可靠,可提取山顶点实际的地形。
【Abstract】 In this article, through the analysis of peak point of mountain morphological characteristics and the expression method of peak point of mountain in contour map, we provided a peak point automatic extraction method based on the self-sealing contour surface. The experimental results show that the method is simple, accurate and reliable, and the extractive peak points have the actual meaning of terrain.
