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.
