摘要
对XML技术和集成策略进行了介绍.针对目前GIS数据集成和共享中出现"GIS应用孤岛"的现状,提出了一个以XML为数据交换模型的地理位置查询系统与GIS之间的数据交换框架,该框架能在考虑共享过程中数据的可靠和效率等问题的基础上,较好地实现地理位置查询系统与GIS之间的实时数据传送和信息共享.
This paper introduces XML technology and integrating strategies. Based on the situation of ＂GIS application isolated island＂ in GIS data integration and share, this paper puts forward a geographic location inquiry system with XML as data exchange model, and a data exchange framework with GIS, which can realize the real data transmission and information sharing between geographic location inquiry system and GIS when the reliability and efficiency in data sharing process are considered.
