摘要
以黑岱沟露天煤矿0.5 m分辨率DEM为例,运用ArcGIS软件,提出一种基于高分辨率DEM的露天煤矿坡顶线与坡底线提取方法.通过计算DEM中坡顶和坡底的平面曲率,利用矿山DEM在坡顶、坡底的平面曲率与坡面、平盘的平面曲率存在差别,从而分离坡顶线和坡底线.该方法操作简便,精度较高,为我国露天煤矿地理信息生产提供了技术支持.
Abstract
Taking the 0.5-meter resolution DEM of Heidaigou open-pit mine as an example,this article proposes a method for extracting the top line and bottom line of open-pit mine based on high-resolution DEM using ArcGIS software.By calculating the planar curvature of the slope top and bottom in the DEM,the top line and bottom line are separated from the difference between the planar curvature of the slope top,bottom and the planar curvature of the slope surface and the flat disc in the mine DEM.This method is simple to operate and has high accuracy,providing technical support for the production of geographic information in open-pit coal mines in China.
