Abstract:The conceptual model system of GIS(Geographic Information System) was discussed, which includes the analysis, investigation and resolvents of GIS conceptual constructure and its inner mechanism such as the fundamental constructure of GIS, information expression of 3-d geographical space, inter-operation of Multi-Bases management and the architecture base of GIS and so on. Three new types of conceptual model system of GIS were produced.
Key words: GIS conceptual model spatial information expression inter-operation of
Multi-Bases management architecture base of GIS
