规则格网DEM以其数据结构简单、计算方法简单，易于和栅格GIS结合，在工程勘察、水文地质等方面的应用得到广泛应用。在架空送电线路，特别是山区的野外勘测工作中，根据航摄数据生成规则格网DEM，利用GIS的数字地形分析功能提取坡度、坡向等地形因子，对其进行处理和分析，能够极大提高工作效率。

Regular grid DEM had be widely used in the field of Engineering Survey and Hydrological Geology taking the advantage of simple data structure and calculation method. In the Overhead Transmission Line project, especial in the mountains, Generated 5m resolution DEM based on 1:10000 digital topographic maps, calculated the topographical factors as slopes and aspect, from the DEM depended on the Digital Terrain Analysis of GIS. This method had be proved to improve work efficiency.
