P. Melchiorrequently observed that the RBAC access decision is directly influenced by the spatiotemporal context of both the subjects and the objects in the system. Currently, there are only a few models (STRBAC, GSTRBAC) in place which specify spatiotemporal security policy on top of the classical RBAC. In th

The reversibility of the map operations has been formalised at the lowest level, as the basic algorithms for addition, deletion and moving of spatial objects.

N. M. Bakhrakhigital imagery data using traditional pixel-wise approaches remains a challenge due to the spectral complexity of urban areas. Object-Based Image Analysis (OBIA) is emerging as an alternative method to produce landcover information. Standard OBIA approaches rely on ima-ge segmentation which partitio
