地理信息系统要想有更大的发展,必须走开放式的道路.Web-GIS软件由于采用了当前主流的通信、应用协议和体系结构,大大增强了GIS软件的开放性.该文主要从Web-GIS的特点、设计和实现的角度阐述了在开发Web-GIS中应考虑的各个要素,详细分析了Web-GIS的体系结构及其各种实现技术,并且提出了对今后发展的一些看法.

It is important for the development of GIS to make GIS more open. The software of Web-GIS is different from traditional GIS software in architecture. It is developed by using client/server system architecture, which is divided into client, application and database. Moreover because it uses common standard protocols of communication and application, such as TCP/IP and HTML, Web-GIS is more open and in of accord with the tendency of GIS in the future. This paper expounds the essential elements of Web-GIS from the point of the features, design and implementation, discusses the system structure of Web-GIS and its technology of how to implement and draws a conclusion that is how to make application distribute properly is the main factor of which is must considered when designing Web-GIS. Moreover this paper puts forward some opinion to the development of Web-GIS in the future.
