“…In this study, the structure of IFC and CityGML is analyzed, and to maintain possible geometric properties during the conversion from IFC to CityGML, an LOD3 shape generation method is studied through a geometric calculation that requires significant calculation time, such as cross calculation. Furthermore, there have been studies on converting automatically from IFC to CityGML through semantic mapping by focusing on object and attribute information conversion [21]. Moreover, there have been study cases on an algorithm that includes semantic mapping, and that generates LOD of CityGML by dividing the inner and outer surface of a given shape [5].…”

Over the last few years, to increase the competitiveness of domestic construction industries, the governments of US, UK, Japan, and other developed countries have introduced Building Information Modeling (BIM) as part of their support policy; as a result, BIM information is increasing rapidly. In this regard, the need for studies on integrating or mapping BIM object information to Geographic Information Systems (GIS) is increasing. These studies have been conducted with the purpose of utilizing the advantages of BIM and GIS; however, many difficulties are encountered in model integration and mapping because of the different schema structures of such studies. In this study, the productivity of the mapping work is improved by developing a method that automates the Level of Detail (LOD) mapping using BIM and GIS standard models, Screen Buffer Scanning-based multiprocessing, Industry Foundation Classes (IFC) model, and the CityGML model. The proposed method can dramatically improve the productivity of LOD shape modeling work because, unlike conventional methods, the proposed method uses multiprocessing. Finally, the developed results are quantitatively evaluated and future study directions are derived.

“…[22] presented an algorithm for automatic conversion of IFC to GML. The algorithm works only on the transformation from swept solid models to the B-Rep. Isikdag and Zlatanova [15] provide preliminary ideas for defining semantic mapping between the IFC data model and CityGML. The purpose of their work was to allow automatic transformation between the two models.…”

“…BIMs are becoming increasingly popular in the geospatial community, and have allowed for the production of a certain amount of work integrating BIM into GIS [3,7,13,14,15,18,22]. BIM is seen as an essential data source for creating a more navigable, interactive and visually realistic information for built environments [18].…”

“…Industry Foundation Classes (IFCs) [16] and City Geographic Markup Language (CityGML) [6] are officially recognized as two standards, and have been independently developed; the former by the International Alliance for In-Initial investigations for modeling interior Utilities within 3D Geo Context 3 teroperability (IAI), which is the standardization body for the AEC/FM community, and the latter by the Open Geospatial Consortium (OGC), which is the standardization body for the geospatial community. As a result, IFCs are not readily usable in GIS and CityGML [1,15,17]. The main problem in the integration of BIMs with geospatial information occurs at the point of transfer of geometric information [22].…”

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 utility is usually created and maintained using Building Information Model (BIM) systems, while exterior utility is stored, managed and analyzed using GIS. Researchers have suggested that the best approach for BIM/GIS integration is harmonized semantics, which allow formal mapping between the BIM and real world GIS. This paper provides preliminary ideas and directions for how to acquire information 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 and UtilityNetworkADE schema, and only in one case there is one-to-many mapping; related to logical connectivity since there is no exact concept to represent the case in UtilityNetworkADE. Many examples are shown of partial IFC files and their possible translation in order to be represented in UtilityNetworkADE classes.

Abstract:There is a growing interest in the integration of BIM and GIS.However, most of the research is focused on importing BIM data in GIS applications and vice versa. Real integration of BIM and GIS is using the strong parts of the GIS technology in BIM, and of course the strong parts from BIM technology in GIS. In this paper a mix of strong parts from both worlds is integrated in a single project. The paper describes the development of a CityGML extension called GeoBIM to get semantic IFC data into a GIS context. The conversion of IFC to CityGML (including the GeoBIM extension) is implemented in the open source Building Information Modelserver.
