In process of building a large,multi-dimensional,complex relational geographical database model against the traditional database model often exists the problem that expressing semantic is too indistinct.In order to solve this problem,this paper studied the law of building the spatial database model in the traditional modeling software,designed the expression and template library of the spatial database model in UML diagrams,and designed the rules of storing in an XML file.What's more,it generated the control database model automatically after importing an XML file into the GIS database.Through the application of the prototype system,it showed that the method of modeling is scalable,easy to modify and visual for building model.
