摘　　要：重点研究了交通网络数据主要内容与相应的3维表达,最后得到交通网络3维GIS数据概念模型,并建立了地理空间数据库;应用Visual Basic和Ao技术对ArcScene进行二次开发,采用建筑物点状3维模拟符号、两张图像交叉构建树木3维模型和道路模型的制作方法,实现了路面及构造物、建筑物和树木的3维可视化,完成了一定范围的3维导航场景。This paper mainly studied content and 3D expression of transportation network data,acquired 3D GIS data model in transportation network, and established geography spatial database;Carried out secondary development of AreScene by using Visual Basic and AO technology,realized 3D Visualization of road, structure, building and trees and completed a range of 3D navigation scene by cross constructing 3D model of trees and road model with 3D simulation point symbol of building and two images.
