基于交通基础地理信息的网络发布研究与实现

近年来随着WebGIS技术的日趋成熟,采用WebGIS技术管理空间数据并进行网络发布,供用户快速查询与使用,实现空间信息的网络共享,为空间数据的充分利用和可视化表达提供了一种有效的解决方案。本文以北京市交通地理信息系统开发为例,探讨了交通基础地理信息的网络发布平台构架设计与实现过程,并针对系统关键技术的原理及实现进行了详细阐述,构建了以J2EE为核心,基于ArcIMS的空间信息服务框架体系,是WebGIS技术在交通领域的集成应用。

Study and implementation of network publish based on fundamental geographical information of communication

With the maturation of the WebGIS technology,it has been used to manage spatial data.The data can be published on the Internet and can be searched and used by users quickly,which has realized the spatial data sharing on the Internet and provided an efficient solution for the full use and visual expression of spatial data.The development of Beijing geographical information system of communication is taken as an example by this paper.The whole course of the design and realization for Web publication based on fundamental geographical information of communication is discussed firstly.Then,the principle and the realization of key technology is introduced in detail,and spatial information service infrastructure based on ArcIMS and J2EE is constructed to realize the integrated application of WebGIS in the field of communication.Finally,the foundation for digital city construction is established at the same time.
