LinkedGeoData – Collaboratively Created Geo-Information for the Semantic Web

By Sören Auer and Jens Lehmann

Abstract

Abstract. In this Semantic Web Challenge submission we present Linked-GeoData, a project which transforms data collected by the OpenStreetMap project into RDF, enriches this data with a light-weight ontology, establishes links to other entities on the Data Web and provides a browser for exploration and authoring of the rich spatial data collection. The amount of data contributed by LinkedGeoData to the Data Web reaches more than 3 billion RDF triples. It contains descriptions of entities with a spatial location such as roads, buildings, shops, pubs, mailboxes. Most of these entities were previously not available on the Data Web. For the ones available, we applied automatic interlinking techniques to DBpedia and thus other LOD datasets with a spatial dimension. In order to explore this wealth of information we implemented a tool, which combines the faceted-browsing approach with a spatial dimension and employs sophisticated data aggregation techniques to facilitate the smooth browsing of this enormous data source.
