The port of a city is a very dynamic environment that houses lots of companies.Ships come and go, and goods are always on the move.Information integration in geographic information systems is of great importance for tracking purposes, and for proactive and reactive incident handling by the port operators.Linked data and semantic web technologies can be of benefit for the integration of both streaming data such as location data about ships, trains and containers, with static data about companies, their activities and storage sites.With current RDF stream processors it is possible to execute SPARQL queries over RDF data streams taking into account static background data.However, none of them is capable of handling GeoSPARQL queries.GeoSPARQL is an extension to the SPARQL query language for processing geospatial data.To address this challenge we extended the RSP engine C-SPARQL with GeoSPARQL support, making it possible to query geospatial data streams.
