  • Background

    Spatial data is crucial for the Semantic Data Web in order to interlink geographically linked resources. The OpenStreetMap project collects, organizes and publishes geo data the wiki way. Currently the 80.000 Open Street Map users collected data about 22.000.000km ways (roads, highways etc.) on earth. 25.000km are added daily. The Open Street Map database also contains a vast amount of structured information about points-of-interest such as for example shops, amenities, sports venues, businesses, touristic and historic sights.

    Aim

    The goal of this project is to publish OSM geo data, interlink it with other data sources and provide efficient means for browsing and authoring. We aim at working as closely as possible with both the OSM and LOD communities.

    Components

    The project currently consists of three components:

    • Open Street Map data extraction currently works on the basis of OSM database dumps. A live-sync module keeps the data in our SPARQL endpoints up-to-date.
    • LinkedGeo Data browser is based on Javascript widgets, which can display the data from the Linked Geo Data SPARQL endpoints. Support for endpoints of other projects in the works.
    • A Server providing a Linked Data Interface and a REST API, that grant access to RDFized data based on a (relational) OSM database.

abstract
  • LinkedGeoData is an effort to add a spatial dimension to the Web of Data / Semantic Web. LinkedGeoData uses the information collected by the OpenStreetMap project and makes it available as an RDF knowledge base according to the Linked Data principles. It interlinks this data with other knowledge bases in the Linking Open Data initiative.
