“…However, the results can be different when using the tools for current models developed within practice. For this reason, four topics were defined, to be further investigated in the GeoBIM benchmark project, using datasets modelled in practice, to assess their actual effectiveness: To facilitate these tasks a set of representative IFC and CityGML datasets were provided [35] and used by external, voluntary, participants in the software or procedure they would like to test [6]. Full details about the tested software and a full list of participants can be found in the respective pages of the benchmark website (https://3d.bk.tudelft.nl/projects/geobim-benchmark/software.html for the tested software and https://3d.bk.tudelft.nl/projects/geobim-benchmark/participants.html for the list of participants.…”

The integration of 3D city models with Building Information Models (BIM), coined as GeoBIM, facilitates improved data support to several applications, e.g., 3D map updates, building permits issuing, detailed city analysis, infrastructure design, context-based building design, to name a few. To solve the integration, several issues need to be tackled and solved, i.e., harmonization of features, interoperability, format conversions, integration of procedures. The GeoBIM benchmark 2019, funded by ISPRS and EuroSDR, evaluated the state of implementation of tools addressing some of those issues. In particular, in the part of the benchmark described in this paper, the application of georeferencing to Industry Foundation Classes (IFC) models and making consistent conversions between 3D city models and BIM are investigated, considering the OGC CityGML and buildingSMART IFC as reference standards. In the benchmark, sample datasets in the two reference standards were provided. External volunteers were asked to describe and test georeferencing procedures for IFC models and conversion tools between CityGML and IFC. From the analysis of the delivered answers and processed datasets, it was possible to notice that while there are tools and procedures available to support georeferencing and data conversion, comprehensive definition of the requirements, clear rules to perform such two tasks, as well as solid technological solutions implementing them, are still lacking in functionalities. Those specific issues can be a sensible starting point for planning the next GeoBIM integration agendas.

“…A number of datasets from several organisations were identified, pre-processed and validated for this benchmark activity (Table 3-see Noardo et al [35] for details). The datasets were chosen to test both the most common features of such data and the main detected issues regarding the interesting but tricky aspects of the format.…”

<p><strong>Abstract.</strong> Much work has been done on quality of geoinformation and interoperability between BIM and GIS. However, the intersection of the two – quality control of the conversion between BIM and GIS – remains uncharted. This discussion paper, based on empirical results, is one of the first steps towards mapping out a framework on errors and quality control in the context of BIM–GIS interoperability. In our work we focus on the conversion from IFC to CityGML, identifying several systematic errors potentially common and/or exclusive to the context of BIM–GIS conversion. Besides exposing several faults pertaining to IFC-sourced 3D city models, we discuss their taxonomy and their potential impact when engaged in applications. This paper is also relevant with respect to the growing popularity of conversion between IFC and CityGML, potentially aiding others to avoid many of the errors that can occur in the process and establishing directions to set up a benchmark to assess the performance of the interoperability workflows.</p>
