GeoReferencing the Semantic Web: ontology based markup of geographically referenced information
نویسندگان
چکیده
Geographic references that include geographic relations to well known locations are useful for explaining real world information and for knowledge discovery. In order to utilize the spatial characteristics of this information on the web, our research takes advantage of recent developments in the Semantic Web community. To circulate geographically referenced information on the Semantic Web, we have created a geographic ontology for describing them and have implemented two tools, a web service that calculates geographic relations, and a plugin to an open-source GIS that allows us to generate RDF of topological and direction spatial relations among geographic features. This ontology based approach allows us to associate geographically referenced data to any other non-spatial information related to the geographic feature that is expressed on the Semantic Web. These two different approaches to developing geographic references for the Semantic Web have provided us with the opportunity to evaluate the advantages and disadvantages of each, providing us with direction for future work.

With the growing dominance of complex and multi-level urban structures, current cadastral systems, which are often developed based on 2D representations, are not capable of providing unambiguous spatial information about urban properties. Therefore, the concept of 3D cadastre is proposed to support 3D digital representation of land and properties and facilitate the communication of legal owners...
