Author Affiliations +
Access control of Geographical Information System (GIS) has more complex spatial constraints than the general MIS system, it makes the classic role-based access control model(RBAC) can't be used in GIS. To achieve an effective Access Control Model for GIS, an extension model of the RBAC is presented in the paper. Firstly, this paper introduce the three kinds spatial constraints that included layer constraints, region constraints and spatial object constraints; Then the paper expanded the basic RBAC model, added regional class, layers class and so on; Finally, the paper has given the system RABC control model as well as the realization method in view of GIS. An extension model of the RBAC is applicable to mobile computing, wireless access and system about location is concluded by analyzing.
