摘要
本文通过使用GIS软件Arc View对某露天矿地形图进行三维化,使得该露天矿地形全貌更直观的展现在使用者面前。具体方法主要是提取该露天矿地形图的三维坐标资料,在Arc View GIS平台上构建边坡三维地表模型,真实再现了原始边坡地形地貌的三维景观。在此模型上对数据资料进行整理,提取等高线、坡度、坡向等信息。
By using GIS software Arcview for a three- dimensional topographic map of the open pit,so that the open pit more intuitive to show the whole picture of the terrain in front of the user. Specific method is to extract the three- dimensional coordinates of the information contained in the open pit topographic map, building a three- dimensional surface model of the slope on the Arc View GIS platform,a true representation of the original slope topography 3D landscape. On this model,data collation,extracted contours,slope,aspect and other information.
