Abstract: Based on the analysis of the development of GIS technology and application, this paper brought forward the concept of CoGIS, namely Cooperative GIS. CoGIS is GIS facing group-users and supporting human-human interaction, which makes it differ from the former GISs. Then, the characteristics of general Computer Support Cooperative Work(CSCW)applications and the complexity of Geographic Information Science were analyzed, and the conclusion that CoGIS was not a simple GIS layer on CSCW was reached. Further, this paper gave the hierarchical architecture of CoGIS, and analyzed the cooperative platform in detail from the following:1)basic elements;2)collaboration patterns;3)cooperation control mechanism;4)synchronization mechanism;5)security and 6)group communication and so on. With those, the problems about GIS applications are discussed, such as 1)distributed multi-source GIS information and knowledge sharing platform;2)the fusion and visualization of GIS information;3)virtual reality cooperative modeling;4)dynamic simulation;5)expert system and 6)decision-making. Finally, this paper analyzed CoGIS application mode in brief.
