摘要
由于规划设计阶段常缺乏地形资料,导致不能进行准确计算,造成设计误差,提出了一种利用Google Earth、GlobalMapper及3DMax等常用软件方便快捷地建立三维地形模型的方法,实现了地形三维可视化,获取大致地貌信息。介绍了模型建立的理论及具体操作步骤,并与常规三维模型成果进行比较和分析,满足规划阶段对地形精度需求不高时的设计要求,进一步论证了这种建模方法的可行性。
The lack of topographic data in the planning and design stage often leads to miscalculation and design errors.A convenient modeling method is put forward by adopting common software,such as Google Earth,Global Mapper,3DMax and so on to achieve the 3D terrain visualization and obtain general information of landscape.The modeling theory and detailed operation steps are introduced.Comparing with other conventional 3D models,the new model can be applied when design terrain precision is not strictly requested in planning stage and the feasibility of the method is further demonstrated.
