Towards an Integration of Gis and Bim Data: What Are the Geometric And Topological Issues?

Abstract

ABSTRACT:Geographic information and building information modelling both model buildings and infrastructure, but the way in which they are modelled is usually complimentary and BIM-GIS integration is widely considered as a way forward for both domains. For one, more detailed BIM data can feed more general GIS data and GIS data can provide the context that is necessary to BIM data. While previous studies have focused on the theoretical aspects of such an integration at a schema level, in this paper we focus on explaining the geometric and topological issues we have found while trying to develop software to realise such an integration in practice and at a data level. In our preliminary results, which are presented here, we have found that many issues for such an integration remain: handling the geometric and topological problems in BIM models, dealing with bad georeferencing and figuring out the best way to convert data between IFC and CityGML are all open issues.

Buildings in GI: How to deal with building models in the GIS domain

“…Additional key publications in terms of BIM/GIS integration include Deng, Cheng, and Anumba (2016), Wang, Krijnen, and de Vries (2016), Arroyo Ohori et al (2017), Ohori, Diakité, Krijnen, Ledoux, and Stoter (2018), and Stouffs, Tauscher, and Biljecki (2018). Additionally, BIM to GIS conceptual mapping (B2GM) is currently being standardized by ISO (2019).…”

“…To carry out BIM/GIS integration, Amirebrahimi, Rajabifard, Mendis, and Ngo () and Liu et al () identified three levels of integration: (1) integration at data level (through linking, translation/conversion, extension and meta‐models/mediation); (2) integration at process level (integration through semantic web technologies or service‐based methods); and (3) integration at application level (integration through reconfiguring or rebuilding). At data level, Liu et al () estimate that the “EEEF” (effectiveness, extensibility, effort, and flexibility) of using new standards and models “highly depends on their ambitions,” but “if the new model aims to solve one particular small and focused problem, […it] can be very satisfying.” They further state that the EEEF of conversion, translation, and extension of existing standards depends on whether it is accomplished in a semi‐automatic way or in a manual way, but both “involve semantic filtering (ignoring or mapping) process,” which usually results in a “certain level of information loss.” Additional key publications in terms of BIM/GIS integration include Deng, Cheng, and Anumba (), Wang, Krijnen, and de Vries (), Arroyo Ohori et al (), Ohori, Diakité, Krijnen, Ledoux, and Stoter (), and Stouffs, Tauscher, and Biljecki ().

A Precise Urban Component Management Method Based on the GeoSOT Grid Code and BIM

“…Currently, the combination of GIS and BIM technologies has become a trend that has great demand. This combination is widely regarded as a major research direction to break through the bottlenecks in current research areas, such as urban management, environmental planning, and emergency management [8][9][10][11][12][13]. This paper also starts from this basis and proposes a new urban management method to meet these needs.…”

Indoor Mesh Classification for Bim

“…Currently the Industry Foundation Classes (IFC) format is used as an open standard format for the BIM objects. According to (Ohori et al, 2017), most IFC objects are built by integrating sweep volumes, explicit faceted surface models and Constructive Solid Geometry (CSG).…”
