基于ArcGIS和SketchUp的三维仿真技术在蔬菜基地规划中的应用

The Application of 3D Simulation Technology in Vegetable Base Planning Based on ArcGIS and SketchUp

以贵州省凯里市平茶现代蔬菜生产示范基地为例,首先将AutoCAD格式的规划数据转为ESRI格式的shape文件,利用SketchUp制作三维模型,并在ArcMap中制作数字高程模型(DEM);然后在ArcScene平台上对DEM、三维模型及矢量数据进行叠加与渲染,实现了三维仿真技术在蔬菜基地规划中的应用;最后针对研究过程中存在的道路与地形匹配问题,提出一种无需编程的解决方案,为三维仿真技术的推广提供了有效借鉴。

Taking the modern vegetable production and demonstration base of Pingcha Town,Kaili City,Guizhou Province as an example,the planning data of AutoCAD was firstly converted to the shape files,and three-dimensional(3D) model was created using SketchUp,then produced the digital elevation model(DEM) by ArcMap.Subsequently,stacked and rendered them with vector data based on ArcScene platform,which realized the application of 3D simulation in vegetable base planning.Concerning the matching dilemma between road and terrain,a non-programming proposal was put forward based on ArcGIS,which provided an effective model for the extension of 3D simulation technology.
