A NEW FORM OF OBJECT ORIENTED SPATIAL DATA MODEL IN GIS

On the basis of analysing the theories of object-oriented, topological relation model and non-topological relation model, this paper presents a new spatial data model. The thinking of new data model accords with the theory of spatial organization. It has its own characteristics compared with conventional data model. All of these ideas have been embodied in factual appliance of spatial analysis, such as overlap analysis, optimal spatial analysis and so on. The concrete analysis process and methods are set forth in the paper in detail, Moreover, this prototype can be applied to other fields, which involve spatial database building, etc.
