摘要
数字地面模型（ＤＴＭ） 在土木工程、测绘、地质等许多领域都有着广泛的应用，本文提出一种可行的ＤＴＭ 构网方法， 此方法可使网格全局和局部均优化， 同时可对网格中出现的平坦三角形进行修改处理。另外， 还给出了便于算法实现的基于三角形的数据结构。
Digital terrain model(DTM) is used widely in many fields, such as civil engineering, topography and geology. This paper presents a feasible method for constructing DTM mesh, and by the method the mesh is optimal generally and locally. The method can also correct the flat triangles appearing in the mesh. In addition, this paper put forth a triangle-based data structure helpful to implement the algorithms.
