The Semantic Geospatial Web is a vision to include geospatial information at the core of the Semantic Web to facilitate information retrieval and information integration. This vision requires the definition of geospatial ontologies, semantic gazetteers, and shared technical vocabularies to describe geographic phenomena. The Semantic Geospatial Web is part of geographic information science.
