| 摘 要： | 专业地理信息系统中,不同用户角色拥有不同用户权限区,这种角色控制方式是适合现行的管理机制的,但该种方式以区域来确定用户权限区的固定角色控制在解决跨区域协作问题存在困难,当事务发展涉及到多个区域时,不能合理有效的信息共享,造成信息系统失效。针对该问题在基于角色的访问控制基础上,提出空间相关的动态角色控制,分析其需要考虑的各个方面,做了详细的设计,探讨了总体结构和核心设计。最后通过一个森林防火地理信息系统中火灾跨区域扑救协作典型实验,来验证空间相关的动态角色控制对解决跨区域协作是可行的。

| Abstract: | 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. |
