“…Nevertheless, semantics could be attached to it through an external database. Overall, for theoretical study purposes, CityGML is more often studied [51][52][53], while for practical purposes, multipatch is more often adopted [33,54,55].…”

“…However, they noted that the OGC specifications provide solutions from only particular views. Donkers et al [16]; Deng et al [17]; Hor et al [31]; Kang and Hong [32]; Knoth et al [33]; Ohori et al [34]; and Vilgertshofer et al [35] are some examples of articles that describe integration between BIM and GIS through schema mapping between IFC and CityGML. Niestroj et al [36] discussed information models for road asset information exchange and noted that InfraGML might be easier to implement than IFC as GIS applications widely support the GML format.…”

“…Transformation of geometry characteristics between IFC and information models based on ISO/TC 211 concepts is a complex issue that has been discussed in many studies (e.g., Donkers et al [16]; Deng et al [17]; Kang and Hong [32] and Ohori et al [16,34]). The main challenge is the use of swept solids and constructive solids for the geometry of products in IFC, while GIS information models use Boundary Representation (BREP) to represent the geometry of features [17].…”

This study aims to improve the interoperability between the application domains of Building Information Modelling (BIM) and Geographic Information Systems (GIS) by linking and harmonizing core information concepts. Many studies have investigated the integration of application schemas and data instances according to the BIM model IFC and the GIS model CityGML. This study investigates integration between core abstract concepts from IFC and ISO/TC 211 standards for GIS—independent of specific application schemas. A pattern was developed for conversion from IFC EXPRESS schemas to Unified Modelling Language (UML) models according to ISO/TC 211 standards. Core concepts from the two application domains were linked in the UML model, and conversions to implementation schemas for the Geography Markup Language (GML) and EXPRESS were tested. The results showed that the IFC model could be described as an ISO/TC 211 compliant UML model and that abstract concepts from ISO/TC 211 standards could be linked to core IFC concepts. Implementation schemas for BIM and GIS formats could be derived from the UML model, enabling implementation in applications from both domains without conversion of concepts. Future work should include refined linking and harmonization of core abstract concepts from the two application domains.

“…In addition, in their implementation the semantics of the objects cannot be stored and thus different tricks are used to recover it for each surface in the final model. Kang and Hong [28] automates the generation of LOD geometries using Screen-Buffer scanning-based Multiprocessing (SB-MP) using semantic mapping rules.…”

Abstract:It is widely acknowledged that the integration of BIM and GIS data is a crucial step forward for future 3D city modelling, but most of the research conducted so far has covered only the high-level and semantic aspects of GIS-BIM integration. This paper presents the results of the GeoBIM project, which tackled three integration problems focussing instead on aspects involving geometry processing: (i) the automated processing of complex architectural IFC models; (ii) the integration of existing GIS subsoil data in BIM; and (iii) the georeferencing of BIM models for their use in GIS software. All the problems have been studied using real world models and existing datasets made and used by practitioners in The Netherlands. For each problem, this paper exposes in detail the issues faced, proposed solutions, and recommendations for a more successful integration.
