基于ArcGIS和Global Mapper软件的三维地形可视化技术的应用

Three-Dimensional Terrain Visualization Application based on ArcGIS and Global Mapper

以某项目的地形测绘为例,阐述基于ArcGIS和Global Mapper软件实现三维地形可视化与测绘的方法及流程,重点论述了数据的采集与处理,三维地形的模拟,海量数据的实时显示,三维地形应用,为用户提供更为直观、实时量测。实践证明:此方法建立的三维地形符合工程应用的要求,具有良好的可行性。

The paper detailed instructions the methods and procedures of three-dimensional terrain visualization and surveying , especially discusses the data acquisition and processing, 3D terrain simulation, massive data real-time display and finally achieved scalability and intuitive as one of the 3D terrain expression, provide the user more direct, precise ter- rain information. Practice has proved, this method to establish the 3D terrain corresponds to engineering application requirements, has the good feasibility.
