City Models

3D city models are important in urban planning for sustainable development. Usually and traditionally, urban planners design the future layout of the towns by drawing the maps, using GIS or CAD packages. 3D city models based on these maps are quite effective in understanding what if the plan is realized. However, creating 3D city models is labor intensive, using a 3D modeling software such as 3ds Max or SketchUp. In order to automate laborious steps, we are proposing a GIS and CG integrated system for automatically generating 3D building models with general shaped roofs by straight skeleton computation, based on general shaped building polygons (building footprints) on digital maps.

The digitalization of the urban development process is driven by the need for informed, evidence-based, collaborative and participative urban planning and decision-making, epitomized in the concept of Smart Cities. This digital transformation is enabled by information technology developments in fields such as 3D city models, Digital Twins, Urban Analytics and Informatics, Geographic Information Systems (GIS), and Planning Support Systems (PSS). In this context, City Information Modelling (CIM) has recently emerged as a concept related to these various technological driving forces. In this article, we review the state of the art of CIM (definitions and applications) in the academic literature and propose a definition and a general conceptual framework. By highlighting how the different disciplines are related to each other within this conceptual framework, we offer a context for transdisciplinary work, and focus on integration challenges, for research and development, both in academia and industry. This will contribute to moving forward the debate on digitalization of the built environment development process in the field of Smart Cities.

Abstract. 3D city models are playing a growing role worldwide as sources of integrated information upon which different urban applications are developed. In the context of urban planning and design, semantic 3D city models can provide plenty of qualitative and quantitative information about the urban context and of the area(s) to be transformed. This paper takes inspiration and continues a work recently published in which several design parameters and Key Performance Indicators are computed from a semantic 3D city model, and later used in a GIS-supported urban design process to develop a new area. As many of such parameters are derived from the gross volume of the building stock, this paper investigates whether and to which extent different building stock models might affect the estimation of the gross volume. The study is carried out in anticipation of the upcoming LoD2-based, country-wide model of the Netherlands that is being finalised by our team. At the same time, the paper investigates whether and which information can be obtained regarding the quality of the LoD2 model from a comparison with the LoD1 one, with a focus on volume calculation.
