摘要: 融合栅格地图技术与矢量标记语言(VML)来解决目前WebGIS应用中存在的响应速度慢等不足,主要研究如何充分发挥二者的优点,构建一个面向企业应用的WebGIS系统,探讨了系统架构设计、WebGIS的数据转换和存储、栅格地图制作、开发包等关键技术。最后,将栅格地图技术与VML融合的WebGIS应用到佛山市水污染监控与应急反应系统中,取得良好的效果。

Abstract: The paper presents a solution to overcome such shortcomings as low response speed etc. of WebGIS application systems,based on hybrid technology which combines the grid map technology with Vector Markup Language(VML).Explore how to exert their advantages to construct an enterprise-application-oriented WebGIS system in details,and discuss the key technologies of WebGIS such as the system architecture design,data conversion and storage,grid map production,development kit etc.Furthermore,apply such WebGIS technology in the system of the water pollution monitoring and emergency response in Foshan city,which obtains good effect.
