基于J2EE的网络三维地形显示系统的研究

Research on web-based 3D terrain visualization system based on J2EE framework

互联网以其丰富的形式和友好的界面渐渐成为显示地理信息的重要中介。在当前地理信息系统中一个比较流行的趋势就是Web3D技术的使用。作为最基础的地理信息之一,地形信息是其他信息(如建筑物,道路,人口密度等等)显示的基础。然而地形在网络上的三维可视化对于低带宽的用户来说是一项巨大的挑战,因为大量的数据需要在网络上传输。本文提出并实现了基于J2EE架构的网络三维地形可视化系统,这种架构和相关的技术也有助于开发基于三维地形可视化的地理信息查询系统。

Internet has become the import medium of displaying Geography Information with its abundant form and friendly interface. Currently, among GIS, a popular trend is the use of Web3D technique. As one of the most basal geography information , terrain is the foundation of displaying other information such as building ,road.population density .However, the 3D visualization of terrain on the internet is a big challenge for a low bandwidth user, because mass data needs to be translated on the internet .This article put forward and realize a 3D terrain visualization system on the internet based on the J2EE framework, this kind of framework and related technique also help to develop querying system of GIS which based on 3D terrain visualization.
