Building Virtual Knowledge Graphs from CityGML Data

Proc. of the 17th Int. Conf. on Location Based Services (LBS 2022). 2022.

In this work, we show how to expose CityGML data as a Virtual Knowledge Graph (VKG). We use 3DCityDB to store the CityGML data, and Ontop to build the VKG. We demonstrate the workflow using the models of the main campus of Technical University of Munich.
