英文摘要	With the development of the network technologies and GIS, spatial data security is becoming more and more important because of the increasing spatial data sharing and interoperation. At the same time, advanced spatial data acquisition technologies are producing mass high-precision data. Therefore, fine-grained access restrictions to spatial data are seriously demanded. However, the existing data access control technologies are inadequate to meet the security requirement of spatial data, especially in fine-grained access control. In this paper, the fine-grained access control of the spatial data issues is discussed in detail. Then, the mechanism of authorization for the fine-grained access control is introduced. Based on Role-based Access Control (RBAC) model, a fine-grained access control model for spatial data is proposed in the grid environment. Finally, a case study is given to prove the feasibility of the proposed model above.; Computer Science, Information Systems; Engineering, Electrical & Electronic; EI; CPCI-S(ISTP); 0
