GIS was developed to WebGIS, from Desktop to Web ,from applying to a few specialists to civilization ,from called "closed" system to Open GIS.In the face of abundant valuable geographical resource. It is important that how to using them from specialty across to information society for ours.In this paper,,the author put forwards the concept of geographical information server system,based on the studying of the characteristic of WebGIS and the technology of information issuance. The main content include two parts: 1-. comprehensive studying the key technology about geographical information serversystem.(GISS)Geographical information server system.(GISS) is a large system project,including GIS(geographical information system) . Internet database technology and so on technique.In this article we study a few of important key technology,for example ,the organization and management of geographical information, issuance and transmission of geographical information browsing information with graphics in Internet and geographical information share and safe. 2, Designing an practical GISS based on the research of studyingIn this paper,We are using the mode of Client/Server.This mode include some parts.First,server can manage the data and non-graphical operation ,for instance,data personality and analysis. Second,a plug-in was installed to disply graphical information. For the convenience,we write an software named Author Server.lt can make personality to data that will issue in the network.In client department,we write some using software for convenience.In conclusion,It can provide newer geographic information to user,and can make geographic information to person geography vision.
