The Geospatial Semantic web addresses the geographic and spatial components of the Semantic Web, which is a project to create the infrastructure necessary for information sharing on the World Wide Web. The sharing should be based on the meaning of the documents. Since the interpretation of meaning is being done by computers another crucial issue is that whatever way this meaning is expressed it has to be machine-readable. Egenhofer highlights the need for a simple canonical form to pose geospatial data queries and methods to evaluate the semantics of the geospatial data sources to fit them to geospatial queries.
Historical Background
In his vision paper about the Semantic Web, Tim Berners-Lee et al. (2001) gives the following example: “at the doctor’s office, Lucy instructed her Semantic Web agent through her handheld Web browser. The agent promptly retrieved information about Mom’s prescribed treatment from the...
