Applying and advancing semantic technology in the geospatial domain is an active area of work. Semantic technology includes ontologies, linked data, and associated languages, standards, and software. Ontologies describe a domain and can be used for semantic understanding. For example, a Semantic Web is enabled by referencing information on web pages to formal ontologies, which give context for a domain and allow automatic processing. Ontologies also enhance search for geospatial data, allow data integration, and can resolve semantic heterogeneity when querying across datasets. Geospatial data are also being put into the resource description framework (RDF) linked data format and made available over the web as part of the linked open data project. Web‐based query languages, such as GeoSPARQL, have been developed that include spatial operators, enabling a Geospatial Semantic Web.
