Integrating 3D city data through knowledge graphs

This paper proposes a framework to represent 3D city models and integrate them with other geospatial data sources like OpenStreetMap by constructing knowledge graphs. Using CityGML and OSM data from Munich, they demonstrated the framework's capability in formulating and answering complex geospatial queries efficiently. The authors use three KG systems (Ontop, Apache Jena, and GraphDB) and discuss advantages of VKG and MKG approaches.
