Spatial View: A Dynamic and Flexible Vision of a Spatial Database
نویسندگان
چکیده
Today geographical databases must provide a dynamic and flexible data model. The notion of spatial view allows different, independent external interpretations of a database schema. A spatial view is an extension of the classical view concept as found in relational databases. A spatial view is a set of atoms. Each atom is defined with a set of database relations, a set of conventional spatial and non spatial database operators and a set of visualization operators. Manipulations of views allow building of new views according to specific needs.

Investigation of the Spatial Resolution and Field of View with Change of Magnification in VRX CT
Introduction: Variable resolution x-ray (VRX) CT is a new type of CT that can image objects at various spatial resolutions. In a VRX CT scanner, the spatial resolution increases at the cost of reduction in the field of view (FOV). An important factor that limits the spatial resolution of the VRX CT is the effect of focal spot size. Also, the optimum magnification is different at each incident a...
