摘要：3D City models have so far neglected utility networks in built environments, both interior and exterior. Many urban applications,e.g. emergency response or maintenance operations, are looking for such an integration of interior and exterior utility. Interior utilityis usually created and maintained using Building Information Model (BIM) systems, while exterior utility is stored, managed andanalyzed using GIS. Researchers have suggested that the best approach for BIM/GIS integration is harmonized semantics, whichallow formal mapping between the BIM and real world GIS. This paper provides preliminary ideas and directions for how to acquireinformation from BIM/Industry Foundation Class (IFC) and map it to CityGML utility network Application Domain Extension(ADE). The investigation points out that, in most cases, there is a direct one-to-one mapping between IFC schema andUtilityNetworkADE schema, and only in one case there is one-to-many mapping; related to logical connectivity since there is noexact concept to represent the case in UtilityNetworkADE. Many examples are shown of partial IFC files and their possibletranslation in order to be represented in UtilityNetworkADE classes.
