Labetski, A. (author), Vitalis, S. (author), Biljecki, Filip (author), Arroyo Ohori, G.A.K. (author), Stoter, J.E. (author)Urban morphology is important in a broad range of investigations across the fields of city planning, transportation, climate, energy, and urban data science. Characterising buildings with a set of numerical metrics is fundamental to studying the urban form. Despite the rapid developments in 3D geoinformation science, and the growing 3D data...journal article 2022

Ledoux, H. (author), Biljecki, Filip (author), Dukai, B. (author), Kumar, Kavisha (author), Peters, R.Y. (author), Stoter, J.E. (author), Commandeur, T.J.F. (author)Three-dimensional city models are essential to assess the impact that environmental factors will have on citizens, because they are the input to several simulation and prediction software. Examples of such environmental factors are noise (Stoter et al., 2008), wind (Garcı́a-Sánchez et al., 2014), air pollution (Ujang et al., 2013), and...journal article 2021

(author), Stoter, J.E. (author)Industry Foundation Classes (IFC), the buildingSMART open standard for BIM, is underused with respect to its promising potential, since, according to the experience of practitioners and researchers working with BIM, issues in the standard’s implementation and use prevent its effective use. Nevertheless, a systematic investigation of these...journal article 2021

(author), Stoter, J.E. (author)OGC CityGML is an open standard for 3D city models intended to foster interoperability and support various applications. However, through our practical experience and discussions with practitioners, we have noticed several problems related to the implementation of the standard and the use of standardized data. Nevertheless, a systematic...journal article 2020

(author), Eriksson, Helen (author), Guler, Dogus (author), Hintz, Dean (author), Stoter, J.E. (author)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...journal article 2020

(author)Standardised data formats and data models are essential for data integration and interoperability, which in turn adds value to data by allowing its reuse in multiple contexts. For this reason, in recent years extensive efforts have been focused on standards development. When representing the built environment, 3D city models and Building...journal article 2020

(author)An investigation into the implementation state of open standards in software is currently ongoing through the ISPRS/EuroSDR ‘GeoBIM benchmark 2019’ initiative, which kicked off earlier this year. The benchmark activity provides a way of assessing and comparing the functionality of different software packages in GIS and BIM in terms of their...journal article 2019

Stoter, J.E. (author), Ho, Serene (author), Biljecki, Filip (author)A significant number of studies has been carried out to establish 3D cadastre solutions to improve the registration of multi-level property. Since the inception of research on 3D cadastres (about 20 years ago), the world around us has changed significantly and this also partly changes the context regarding 3D cadastre: technology (e.g....journal article 2019

Noardo, F. (author), Arroyo Ohori, G.A.K. (author), Biljecki, F. (author), Krijnen, Thomas (author), Ellul, Claire (author), Harrie, Lars (author), Stoter, J.E. (author)GeoBIM, the integration of 3D geoinformation (Geo) with building information models (BIM), is a subject of increasing attention in both domains. A well-known practical challenge for this integration is the mixed state of software support for open standards in each domain that would ease the integration. This is often known by practitioners but...journal article 2019

Biljecki, F. (author), Ledoux, H. (author), Stoter, J.E. (author)Elevation datasets (e.g. point clouds) are an essential but often unavailable ingredient for the construction of 3D city models. We investigate in this paper to what extent can 3D city models be generated solely from 2D data without elevation measurements. We show that it is possible to predict the height of buildings from 2D data (their...journal article 2017

Biljecki, F. (author), Ledoux, H. (author), Stoter, J.E. (author)‘Level of Detail’ (LoD) is een veel gebruikt begrip in de 3D-geoinformatie wereld. Het detailniveauvan 3D-data speelt een rol bij de verschillende stappen in de 3D informatie keten, van inwinning tot gebruik. LoD is ook een van de belangrijkste basisprincipes van de internationale standaard CityGML, waarop de optionele 3D uitbreiding van IMGeo...journal article 2017

Biljecki, F. (author), Heuvelink, GBM (author), Ledoux, H. (author), Stoter, J.E. (author)There has been a great deal of research about errors in geographic information and how they affect spatial analyses. A typical GIS process introduces various types of errors at different stages, and such errors usually propagate into errors in the result of a spatial analysis. However, most studies consider only a single error type thus...journal article 2017

(author)This article reports on the first 3D cadastral registration in The Netherlands, accomplished in March 2016. The solution was sought within the current cadastral, organisational, and technical frameworks to obtain a deeper knowledge on the optimal way of implementing 3D registration, while avoiding discussions between experts from different...journal article 2017

Biljecki, F. (author), Arroyo Ohori, G.A.K. (author), Ledoux, H. (author), Peters, R.Y. (author), Stoter, J.E. (author)The remote estimation of a region’s population has for decades been a key application of geographic information science in demography. Most studies have used 2D data (maps, satellite imagery) to estimate population avoiding field surveys and questionnaires. As the availability of semantic 3D city models is constantly increasing, we investigate...journal article 2016

Biljecki, F. (author), Ledoux, H. (author), Stoter, J.E. (author), Vosselman, G. (author)The level of detail (LOD) of a 3D city model indicates the model's grade and usability. However, there exist multiple valid variants of each LOD. As a consequence, the LOD concept is inconclusive as an instruction for the acquisition of 3D city models. For instance, the top surface of an LOD1 block model may be modelled at the eaves of a...journal article 2016

Biljecki, F. (author), Ledoux, H. (author), Stoter, J.E. (author)The level of detail (LOD) concept of the OGC standard CityGML 2.0 is intended to differentiate multi-scale representations of semantic 3D city models. The concept is in practice principally used to indicate the geometric detail of a model, primarily of buildings. Despite the popularity and the general acceptance of this categorisation, we argue...journal article 2016

Biljecki, F. (author), Stoter, J.E. (author), Ledoux, H. (author), Zlatanova, S. (author), Coltekin, A. (author)In the last decades, 3D city models appear to have been predominantly used for visualisation; however, today they are being increasingly employed in a number of domains and for a large range of tasks beyond visualisation. In this paper, we seek to understand and document the state of the art regarding the utilisation of 3D city models across...journal article 2015

Arroyo Ohori, G.A.K. (author), Ledoux, H. (author), Biljecki, F. (author), Stoter, J.E. (author)The various levels of detail (LODs) of a 3D city model are often stored independently, without links between the representations of the same object, causing inconsistencies, as well as update and maintenance problems. One solution to this problem is to model the LOD as an extra geometric dimension perpendicular to the three spatial ones,...journal article 2015

Biljecki, F. (author), Ledoux, H. (author), Stoter, J.E. (author)Cities are increasingly adopting 3D city models for 3D visualisation, computing solar panel potential of roofs, and other applications. In a similar way to traditional maps, 3D models are an abstraction of the real world: certain elements are simplifi ed or omitted. The amount of detail that is captured in a 3D model, both in terms of geometry...journal article 2014
