摘要
介绍了Ajax技术的基本概念及其关键技术,以ArcIMS为例分析了传统的网络地理信息系统(Web GIS)在数据传输模式和客服交互方式等方面存在的不足,阐述了在Web GIS中使用Ajax技术带来的优势,如减轻服务器的负担、平衡服务器和客户端的负载、无刷新更新页面、减少用户心理和实际的等待时间、实现地图的动态更新、实现地图的可视化交互以及开发效率高等,并指出在Web GIS中使用Ajax技术应该注意的诸如兼容性和用户习惯等问题。Ajax技术的应用将会为传统的Web GIS带来新的生命力。
Introduced the basic concepts and key technologies of Ajax, analysed the existing inadequate of the traditional Web geographic information system （Web GIS） in the data transmission mode and customer - service interactive mode, taking AreIMS as an example; Expounded the advantages of using the Ajax technology in Web GIS, such as reducing the burden of balancing the server and client load, updating pages without refreshing, reducing users＇ psychological and actual waiting time, updating the map dynamically, implementing the map＇s visual interactive, developing high efficiently, and so on. Then pointed out some problems which should be paid attention to when using the Ajax technology in Web GIS,such as compatibility and user habits and other issues. Ajax technology applications for traditional Web GIS will bring new vitality.
