文摘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 facinggroup-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 thecomplexity of Geographic Information Science were analyzed, and the conclusion that CoGIS was not asimple GIS layer on CSCW was reached. Further, this paper gave the hierarchical architecture ofCoGIS, and analyzed the cooperative platform in detail from the following: 1) basic elements; 2)collaboration patterns; 3) cooperation control mechanism; 4) synchronization mechanism; 5) securityand 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 fusionand visualization of GIS information; 3) virtual reality cooperative modeling; 4) dynamicsimulation; 5) expert system and 6) decision-making. Finally, this paper analyzed CoGIS applicationmode in brief.
