摘要
叙述了对多种来源的地形矢量数据用有限元法、辐射搜索法内插建立DEM的方法 ,并介绍了根据算法模型建立“数字高程模型生成系统”的组成以及各个部分的功能。
In this paper, the method to build DEM using multi input terrain vectorized data is described, which uses finite element algorithms and radiation looking judged algorithms, And the components and their functions of ‘DEM generation system’ are introduced.
