TOWARDS CITY INFORMATION MODELING

Following efforts from industry on the Building Information Modeling (BIM) paradigm in extending Industry Foundation Classes (IFC) to infrastructure, and from academia with studies on integration of BIM and Geographical Information Systems (GIS), it is considered the relevance of this scenario in the future development of a City Information Modeling (CIM). This scenario translates in the search for the appropriate model that captures the semantics and geometric representation of objects that belongs to the context of a city. Semantics is the most important part, as it allows for the application of the model to different types of analysis and simulations. This article will treat specifically of the initiatives of the buildingSMART to introduce roads, tunnels, bridges, and earthwork in IFC4, which are in common accord with CityGML and InfraGML/LandXML from Open Geospatial Consortium (OGC). In this manner, it will be discussed the literature focused in the integration of BIM and GIS to analyze the impact of these solutions to the future of CIM. The work constitutes itself in a theoretical discussion, of exploratory character, to understand the possible ways in the development of CIM.
