Automatic detection and modeling of intersections in 3D roads model based on GIS;
基于GIS的三维道路模型交叉口自动检测与建模
Most of RoadCAD software can create 3D road model, but some designers didn t provide 3D model and interim data to the investor.
大部分道路CAD软件均有建立三维道路模型的功能,但一般设计单位并不会把三维模型和中间数据文件提供给甲方,而有时甲方需要应用这些模型和数据,这就给建模工作创造了一定的难度。
