Arroyo Ohori, G.A.K. (author), Ledoux, H. (author), Stoter, J.E. (author)The concept of spacetime has long been used in physics to refer to models that integrate 3D space and time as a single 4D continuum. We argue in this paper that it is also advantageous to use this concept in a practical geographic context by realizing a true 4D model, where time is modeled and implemented as a dimension in the same manner as the...journal article 2017

Echevarria Icaza, L. (author), van den Dobbelsteen, A.A.J.F. (author), van der Hoeven, F.D. (author)The purpose of this research is to analyse the thermal behaviour of South Holland provincial parks during heat waves, in order to provide design adaptation guidelines to increase their cooling capacity over the hotspots present in their urban surroundings. This research analyses the thermal behaviour of different land use patches (forests,...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

Gil, J.A. (author)This thesis proposes a framework for evaluating the mobility potential and performance of urban areas in the city region, as an instrument to support urban development that contributes positively to regional sustainable mobility objectives. The research takes a quantitative approach, modelling and measuring the characteristics of a city-region...doctoral thesis 2016

Arroyo Ohori, G.A.K. (author), Ledoux, H. (author), Stoter, J.E. (author)An alternative to the traditional approaches to model separately 2D/3D space, time, scale and other parametrisable characteristics in GIS lies in the higher-dimensional modelling of geographic information, in which a chosen set of non-spatial characteristics, e.g. time and scale, are modelled as extra geometric dimensions perpendicular to the...conference paper 2016

Oliveti, M (author), van der Spek, S.C. (author), Quak, C.W. (author)With the help of technologies such as GPS tracks, GIS and open data is now possible to study people travel behaviour in a new way. Nowadays, large datasets can be easily handled thanks to databases and better visualized using GIS. Moreover, the availability of GPS data, open data and VGI makes accessible a lot of new information, which was not...conference paper 2016

Nijhuis, S. (author)There is evidence that the potential of GIS is still underutilized in landscape design and research due to a lack of awareness and prejudice. This paper explores some concepts of GIS-based analysis which link to the very heart of landscape design in a natural and intuitive way. Hence the possibility to break down barriers of using GIS in...conference paper 2016

Rook, Merwin (author), Biljecki, F. (author), Diakite, A.A. (author)The lack of semantic information in many 3D city models is a considerable limiting factor in their use, as a lot of applications rely on semantics. Such information is not always available, since it is not collected at all times, it might be lost due to data transformation, or its lack may be caused by non-interoperability in data integration...conference paper 2016

Nijhuis, S. (author)Despite its widespread availability there is evidence that GIS is underused in the realm of landscape design research. Though recognized as a useful tool for mapping and planning, the potential of GIS is often still underutilized due to a lack of awareness and prejudice. This paper explores some concepts of GIS-based analysis which link to the...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

Nijhuis, S. (author)Landscape design research is important for cultivating spatial intelligence in landscape architecture. This study explores GIS (geographic information systems) as a tool for landscape design research – investigating landscape designs to understand them as architectonic compositions and to acquire design knowledge that can be used in the creation...doctoral thesis 2015

Arroyo Ohori, G.A.K. (author), Ledoux, H. (author), Stoter, J.E. (author)3D city models of the same region at multiple LODs are encumbered by the lack of links between corresponding objects across LODs. In practice, this causes inconsistency during updates and maintenance problems. A radical solution to this problem is to model the LOD of a model as a dimension in the geometric sense, such that a set of connected...conference paper 2015

Few attempts were made to exploit bedding attitude (BA) data (or data on similar types of rock discontinuities) in statistical or physically based models for regional slope stability analysis.

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

Ye, Y.E. (author), Van Nes, A. (author)Many new towns are established in China with the intention of providing desirable places to live. Nevertheless, these new towns often lack the flourishing street life, small businesses, and variety of social activities that old towns have to offer. This paper explores the spatial reasons why old towns tend to perform socio-economically better...journal article 2014
