摘要
通过对已有地形图进行矢量化提取高程信息,选用不规则三角网建模技术,借助于ArcGIS软件,生成数字高程模型,并对其进行了精度评定,结果表明:该方法建立数字高程模型的精度满足规范要求。
In this paper, we draw elevation information according to vectofization existing topography, select Triangulated Irregular Network （TIN） as modeling technology, and apply for the software of ArcGIS to construct DEM. In the end, the accuracy assessment is made. The result demonstrates that this method can satisfy the standard requirement of constructing the Digital Elevation Mode.
