“…Via a literature review, it has been noticed that this technique has been integrated into BIM-to-GIS data conversion [16,25,59]. For instance, OCCT was involved in data conversion as a part of IfcOpenShell, which is a common tool for parsing IFC files [25,49] and has been used by many applications, such as BIMserver [60].…”

The development of a smart city and digital twin requires the integration of Building Information Modeling (BIM) and Geographic Information Systems (GIS), where BIM models are to be integrated into GIS for visualization and/or analysis. However, the intrinsic differences between BIM and GIS have led to enormous problems in BIM-to-GIS data conversion, and the use of City Geography Markup Language (CityGML) has further escalated this issue. This study aims to facilitate the use of BIM models in GIS by proposing using the shapefile format, and a creative approach for converting Industry Foundation Classes (IFC) to shapefile was developed by integrating a computer graphics technique. Thirteen building models were used to validate the proposed method. The result shows that: (1) the IFC-to-shapefile conversion is easier and more flexible to realize than the IFC-to-CityGML conversion, and (2) the computer graphics technique can improve the efficiency and reliability of BIM-to-GIS data conversion. This study can facilitate the use of BIM information in GIS and benefit studies working on digital twins and smart cities where building models are to be processed and integrated in GIS, or any other studies that need to manipulate IFC geometry in depth.

“…Based on comprehensive BIM-GIS integration, in the future, the urban stakeholders, including governments or single residents, will be able to create a sustainable living environment [1] through more intelligent and approachable management patterns for energy management or lifecycle management. To realize this schema-level forge, plenty of researchers [3][4][5][8][9][10][11][12][13] have been endeavoring for years on analyzing and refactoring those two notable vendor-neutral data standards, IFC and CityGML. IFC (Industry Foundation Classes) is designed to describe the indoor building environment, and complementarily, CityGML (City Geography Markup Language) conveys the outdoor urban environment as more powerful.…”

“…To make up for the conceptual incompatibilities in both data structures, the researchers have generally followed two respective measures: embedding BIM to GIS or merging them into a uniform, customized data structure. e first attempts include geometric representation transforming [8,9,13], georeferencing [10], property mapping [11], multiscale geometric semantic modeling [2], and geometric translation through an indirect path [12]. At the same time, the second attempt involves developing an integrated data model for underground utility management [3] and presenting an ontology-based general data model for integration [4,5].…”

Constructing a fully mapped virtual world is the premise of establishing the digital twin system; thus, the integration of BIM (Building Information Modeling) and GIS (Geographic Information System) constitutes a fundamental part of the mature digital twin. Although quite a few theoretical unified data models of BIM and GIS integration have been presented in precedent research, the practical web-based applications and software support for real-world city information modeling are still difficult to achieve. One of the challenges is storage inefficiency. It thence leads to burdens in exchange and analysis, which hugely impede the realization of virtual-real fusion. To address that issue, in this research, we contribute to exploring an HDF- (Hierarchical Data Format-) based, innovative, and synthesized scheme with three significant technical processes. First, data reorganization trims the original data with efficient redundancy elimination and reordering for IFC-SPF (IFC STEP Physical File) and XML-encoded CityGML (City Geography Markup Language). Next, bidirectional transformation methods for BIM and GIS modeling data, images, and analytical data into HDF are proposed. They retain the entities and relationships in modeling data and can further improve the compactness and accessibility by ultimately 60%–80% which saves 497,612 KB from 565,152 KB in the test of ZhongChun transformation substation. Finally, data aggregation enhances the bond of the integrated model and heterogeneous data resources from the transformed HDF files. The case studies show that the approach proposed in this paper could reach high efficiency for practicability of the BIM + GIS integration model. This light-weight integration method can further improve the front-end service responsiveness in digital twin applications.

“…The compatibility of the Web, BIM and GIS environments coordinate systems is one of the major sticking points in collaboration of these environments (Arroyo Ohori et al, 2018). Some efforts are being made in this direction, for example, Xu et al (2020) presented a good solution for the BIM model representation in a GIS environment with the aim of quick rendering in the WebGL environment where Cesium library has been used for the web visualization and Autodesk Revit for the IFC file export. The main advantage of proposed solution is in using 3D tiles for model representation that are generated on the model conversion step.…”

Geographical information systems (GIS) and Building information modelling (BIM) provide digital representation of building, its elements and environment. BIM focuses on micro-level representation of buildings and its elements, and GIS provide macro-level representation of the external elements of environment. Their combination can provide a comprehensive view of a built environment based on integrated data. There is an opportunity to make BIM and GIS unity not only to combine them in a single project but also to make a fully merged environment with difficult associations that extend the capabilities of both. Paper presents method that allows visualization and processing the BIM model in the web browser, external processing and analyzing, easy sharing and visualization, linking the 3D model and attribute information, working with the BIM model and GIS data, digital City mapping and etc. The developed method creates rich future for full BIM software products with all manner of functions and tools that will work through the Internet without installations, distributives, additional programs. The introduced technique can be used as a new part for BIM execution planning.
