The development of geography-based services and systems has created the demands in which access control is the primary concern for geospatial data security. Although there are a variety of models to manage geospatial data access, none of them can fulfil the access control requirements. The objective of this paper is to propose a model that can support both spatio-temporal aspects and other contextual conditions as well as access control based on the role of subject. We call this model Spatial Temporal Role Based Access Control (STRoBAC). In addition, we propose an extension of GeoXACML framework, which is highly scalable and can help in declaring and enforcing various types of rules, to support the proposed model. This is the crucial contribution of our research compared to the existing approaches and models.
