面向网络服务的公路地理信息三维可视化研究初探

he three-dimensional visualization of Road's geographic information is an important topic in the fields of road's informatization. It impacts on the entire life cycle of design, construction and operation of the road, so this study is deep significance. In particular, with the rapid development of the network technology, the researches on how to edit and interact with the three-dimensional data through network become focus. Based on the existing research of three-dimensional visualization, this paper put forward and builds a three-dimensional visualization system of road's geographic information, and enables multiple users online editing and operation of Highway geo-data on internet, it provides a powerful tool to support the road management collaborative designing and planning.
