Huang, J. (author), Stoter, J.E. (author), Peters, R.Y. (author), Nan, L. (author)We present a fully automatic approach for reconstructing compact 3D building models from large-scale airborne point clouds. A major challenge of urban reconstruction from airborne LiDAR point clouds lies in that the vertical walls are typically missing. Based on the observation that urban buildings typically consist of planar roofs connected...journal article 2022

Stoter, J.E. (author)De digital twin wordt gezien als een veelbelovende technologie om grote omgevingsvraagstukken op te lossen, zoals de energieransitie en huisvesting. Maar hoe zorgen we ervoor dat omplementaties niet beperkt blijven tot afzonderlijke - veelal technische - deeloplossingen? Volgens Jantien Stoter kunnen antwoorden komen uit het geo-datadomein dat...journal article 2022

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

Vitalis, S. (author), Arroyo Ohori, G.A.K. (author), Stoter, J.E. (author)Level of Detail (LoD) is a well known concept in 3D city models, used to designate different geometric detail that can be used in different applications. Nevertheless, multi-LoD datasets are hard to maintain and manage because of their intrinsic complexity. Versioning is a solution that aids in the storage and management of big and complex...journal article 2022

(author)In the last 15 years semantic 3D city models have seen a steady growth in terms of creation and adoption. Many cities world-wide have now at least one city model which can be used for several applications. Energy- and sustainability-related topics are among those that have experienced a noteworthy increase of interest from the Geomatics...journal article 2022

Noardo, F. (author), Wu, T. (author), Arroyo Ohori, G.A.K. (author), Krijnen, T.F. (author), Stoter, J.E. (author)To support building permit issuing with automatic digital tools, the reuse of models produced by designers would make the process quicker and more objective. However, current studies and pilots often leave a gap with respect to the models as actually provided by architects, having varying quality and content. In this study, rather than taking...journal article 2022

Peters, R.Y. (author), Dukai, B. (author), Vitalis, S. (author), van Liempt, J.N.H. (author), Stoter, J.E. (author)In this paper, we present our workflow to automatically reconstruct three-dimensional (3D) building models based on two-dimensional building polygons and a lidar point cloud. The workflow generates models at different levels of detail (LoDs) to support data require-ments of different applications from one consistent source. Specific attention...journal article 2022

Tufan, Ö (author), Arroyo Ohori, G.A.K. (author), León Sánchez, C.A. (author), Agugiaro, G. (author), Stoter, J.E. (author)3D city models are frequently used to acquire and store energy-related information of buildings for energy applications. In this context, CityGML is the most common data model, and the Energy ADE, one of its most complex extensions, provides a systematic way of storing detailed energy-related data in XML format. Contrarily, even though...journal article 2022

Stoter, J.E. (author), Arroyo Ohori, G.A.K. (author), Noardo, F. (author)The concept of the digital twin has been gaining significant momentum in the geospatial domain since 2016. Although there is some consensus on the basic features of a digital twin, some critical reflection is still necessary to make the concept tangible. Only then can the digital twin be implemented as a technical solution that scales to real...journal article 2021
