Abstract
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.
