利用DLG数据高效高质量生成DEM的方法研究

High Effective and Qualitative Generation Method of DEM Based on DLG

通过对DLG数据的分析,研究了一套基于ArcGIS平台快速自动加密高程点的方法。提出了利用DLG数据高效高质量生成DEM的工艺流程,对大面积区域的DEM快速制作与更新有较好的借鉴作用。

This paper analyzed the DLG identity, and discussed the method of auto-adding points with height based on ArcGIS. And then, the paper brought out the whole process of generating high effective and qualitative DEM using DLG, which was useful to generate DEM quickly for huge zones.
