Spatial Data in the Semantic Web

In order to employ the Web as a medium for data and information integration, comprehensive datasets and vocabularies are required as they enable the disambiguation and alignment of other data and information. Many real-life information integration and aggregation tasks are impossible without comprehensive background knowledge related to spatial features of the ways, structures and landscapes surrounding us. One of the central projects in this area is LinkedGeoData, in which data from OpenStreetMap is converted to RDF and linked to other knowledge bases.
