摘要
以福建省泰宁县为例，详细给出了在Surfer 8.0中利用地形图生成DEM数据的具体流程和实际步骤，并进一步在Erdas Image 8.7中生成了坡度坡向图和三维模拟飞行，经实践证明该方法确实能快速有效的生成大批量的DEM基础数据，且经济实用，为其它地区批量生成DEM和DEM的应用提供了借鉴。
Based on the geographic data from Taining county of Fujian Province,this paper listed detailed procedures and specific steps of building DEM from topographic data by Surfer 8.0 and producing slope graph,aspect graph and three-dimension simulating flight in Erdas Image 8.7.This method proved to be practical and effective in building DEM rapidly and economically.It sets an example of building and applying DEM.
