The Concept of CoGIS
协同GIS——COGIS概念初探

Based on the analysis of the development of GIS application and technology, this paper brought forward the concept of CoGIS, namely Cooperative Operation GIS. Outer space earth man computer relationship in CoGIS was analyzed, CoGIS was GIS supporting human human interaction, and geographical information group communication in CoGIS was discussed, all of which made it differ from former GISs. CoGIS should embody the human oriented idea. Then, the characteristics of general CSCW application and the complexity of Geographical Information Science were analyzed, and the conclusion that CoGIS was not a simple GIS layer on CSCW was reached. Further, this paper brought forward the research content of CoGIS, and discussed some of them in detail as following: modeling theory and system architecture, distributed multi source GIS and knowledge sharing platform, group spatial decision making, CoGIS and VR(virtual reality), CoGIS and multi agents. Finally, this paper analyzed CoGIS application mode in brief.
