IFC to CityGML Transformation Framework for Geo-Analysis: A Water Utility Network Case

摘要: The development of semantic 3D city models has allowed for new approaches to town planning and urban management (Benner et al. 2005) such as emergency catastrophe planning, checking building developments, utility networks. Utility networks inside buildings are composed pipes cables located between ceilings walls (examples these systems include sewerage, electrical, gas, water). traditional representations in 2D, associated with different drawbacks, the overlapping lines representing networks, vertical elements (which can be represented only points) missing (Du Zlatanova 2006). Moreover, topological analyses not possible by using this 2D geometric representation. Therefore, interest representation infrastructures is rapidly increasing. purpose incorporating into GIS modelling them topologically rather than geometrically. Geospatial analysis network requires path point connections elements, instead their geometry. On other hand, CAD/BIM offer a rich geometrical Developing system that supports both capabilities still feasible, thus best approach concentrate on CAD/BIM-GIS interoperability at data level (Wu Hsieh 2008). Detailed information about utilities infrastructure obtained from design real-world models, which could automatically exchanged if formal framework, would made available. In paper, we investigate possibility integrating BIM based user cases defined water maintenance operations management. CityGML been employed study base model provide an integrated ontology covering concept within one framework. work includes developing software component automatic conversion IFC CityGML, analysing already developed functions.
