TRENDS IN BIM AND GIS STANDARDIZATION – REPORT FROM THE JOINT ISO/TC59/SC13–ISO/TC211 WG: GIS-BIM

Abstract. This paper for the keynotes of the MVPBIM 2022 conference gives an overview of the current standardization efforts in the GIS/BIM context. The motivation for this paper is to strengthen the general awareness of BIM/GIS standardization and to promote the technical report ISO/TR 23262:2021 (ISO/TR) to academia and professional engineers. The ISO/TR was developed by the ISO/TC59/SC13-ISO/TC211 Joint Working Group 14 GIS-BIM interoperability (JWG14) and is presented and discussed in detail. The report identifies barriers and opportunities for BIM/GIS interoperability and suggests further specific standardization efforts. All results of the ISO/TR relate to standardization, not to mathematical foundations nor software products. The ISO/TR shows how diverse the standardization efforts for data structures, services, content and processes are, when it comes to the interoperability of digital twins of the built environment. In conclusion, future trends in GIS-BIM standardization will be anticipated and the need for standardization is shortly presented on two practical examples.
