摘　　要：万维网地理信息系统(WebGIS)是传统GIS发展的必然趋势,WebGIS的出现,使在全球范围内实现地理信息资源的网上发布与共享成为可能。但在其发展过程中存在很多问题,例如GIS数据共享、传输速度慢等。因此必须在现有的网络和硬件条件下,从软件方面解决系统图形网络传输的速度问题。为此采用SVG矢量图构建WebGIS图,使用JavaScript脚本语言对SVG进行开发,实现其交互功能,具有系统简单、传输速度快且交互能力强等优点。World Wide Web Geographical Information System （WebGIS） traditional GIS is the inevitable trend of development, WebGIS can make the realization of the global geographic information resources, web publishing and sharing possible. However, in the course of its development, there are many problems, such as being slow in GIS data sharing, transmission. It is necessary in the existing network and hardware conditions, from the graphics software to solve the system＇ s speed network transmission. To this end the use of SVG vector construct WebGIS map, use the JavaScript scripting language for SVG development, to realize their interactive features, has a simple, fast and interactive transmission capability.
