Geospatial Interoperability for IFC and CityGML: Challenges of Existing Building Information Databases
2008 (English)In: Proceedings of Innovations 08th, IEEE Conference, Dubai, December 16-18, 2008Conference paper (Refereed)
CityGML is a XML based standard for geographical information related to the outdoor activities where urban objects can be represented and linked in different spatial relationships. Industrial Foundation Classes (IFC) standard on the other hand looks at buildings in more detailed picture that represents internal constructional and non-constructional objects. Interoperability between CityGML and IFC, i) leads to creation of a common standard for integrating 3D city (indoor and outdoor) applications, ii) provides an integrated view to decision makers for multi leveled analysis and for launching fast responses against crises. The purpose of this paper is to elicit prerequisites of interoperating CityGML and IFC. For this purpose, we have proposed a geospatial interoperability model, and applied it on a case study. The main challenges faced are related to spatial data integration issues. These issues include tabular data related aspects (such as schema matching problems and heterogeneity of sources) as well as spatial aspects (such as missing geometrical information and complexity of geometrical information presentation).
