摘　　要：构建基于网络的城市3维空间信息服务系统,需要解决海量3维地形数据、影像数据和纹理数据的网络传输,以及客户端场景渲染绘制实时处理能力等问题。针对3维空间信息可视化功能日益复杂的特点,利用网格服务的前沿技术,将现有的3维可视化处理环境服务封装为服务组件并进行网格化部署,充分利用集群网络上的计算和服务资源,实现网络3维数据的高效实时绘制与服务。To realize a web 3D spatial information service system, it is very important to solve the problems such as the transmitting of a large amount of 3D terrain data, image data and texture data, the real-time control of scene on client. Because of the variety and complexity of 3D spatial information visualization function, it is necessary to build a Web-based 3D visualization service system according to the edge technology of grid service. By enveloped existing 3D visualization control environment as a service component and deployed them on grid environment, the computing and service resources on computer clusters were made full of use and the highly effective and real-time control and service of Web 3D spatial data was realized. At last an example of 3D visualization on GridGIS platform was given.
