Ontological exploration of geospatial objects in context

Structured study of spatial objects and their relationships leads to a better cognition of the geospatial information and creates the concept of context at a higher level of abstraction. This study is aimed at providing a comprehensive definition of the context for geospatial objects. A combination of binary qualitative spatial relationships (i.e. direction, distance, and topological relations) among the members of a set of spatial objects will be used accordingly. In addition, by incorporating the general concept of context, obtained from either static data (attributes in a database) or dynamic data (sensors), the compact context of spatial objects will be introduced. Our framework for presentation of the involved knowledge and conception about the objects in context is also explored using ontology and description logic because of powerful conceptualization of relationships, either spatial or non-spatial, integrally. For this purpose, the hierarchies of main structure and object properties are formed at ...
