In GIS application system,different users have diverse jurisdiction district,which is available for existing management mechanism.But in this way,there is difficult to dispose the cross region cooperation question in which determining the user role by the area.When the business need cross region,it is not to share information and cause information system invalid.This paper proposes the spatial-based dynamic roles control,which is based on the theory of role-based access control.It offers an analysis of several aspects,makes a thorough and careful design,and discusses the overall organization and core design.Finally it provides an example,a Wildfire Alarm and Prevention GIS,to prove it feasible.
