Abstract

Interoperability is the main burden on the way to efficiently acquiring spatial data on the web. Significant contributions regarding interoperability have been made by the Open Geospatial Consortium (OGC), where web service standards to publish and download spatial data have been established. Publishing spatial data on the Web as linked data is being carried on by the OGC initiative GeoSPARQL, which has generated comprehensive vocabulary and spatial query techniques. While OGC web services standards are widely implemented in Geographic Information Systems (GIS) and offer a seamless service infrastructure, the LOD approach offers structured techniques to interlink and semantically describe spatial information. It is currently not possible to use LOD as data source for OGC web services. In this project we make a suggestion for technically linking OGC web services and LOD as a data source, and we explore its benefits. We create an adapter that enables access to geographic LOD datasets from within OGC Web Feature Service (WFS), enabling most current GIS to access the Web of Data.
