Spatial Parameters for Circular Construction Hubs: Location Criteria for a Circular Built Environment

Implementing a circular economy in cities has been proposed by policy makers as a potential solution for achieving sustainability in the construction sector. One strategy that has gained interest by both policy makers and companies is to develop “circular construction hubs”: locations that collect, store, and redistribute waste as secondary...

The influence of the exponential demand for EV infrastructure on Utrecht's aspiration to become a 10-minute city

All over the world, cities are attempting to emit less carbon to limit the possibly detrimental effects of human-induced climate change. One way to limit carbon emissions is by reducing fossil fuel car use and transitioning to forms of low-carbon mobility. Electric vehicles (EVs) are an exponentially popular low-carbon transport solution,...

From GIS to 3D flow simulations in urban environments

Urban physics is a multi-scale and interdisciplinary field, that combines science and engineering for the study of physical processes in urban areas. Computational Fluid Dynamics (CFD) is considered a powerful tool for the study of these processes. In the context of microscale phenomena these processes refer to the transfer of heat and mass in...

Mapping as Gap-Finder: Geddes, Tyrwhitt, and the Comparative Spatial Analysis of Port City Regions

Politicians, planners, and mapmakers have long used mapping to depict selected spaces, to document natural and humanmade changes within them, and to identify spaces where planning intervention is needed or can be helpful. Recent innovations involving big data, GIS-based research and digital datasets offer opportunities for maps and mapping that...

A Survey on the Adoption of GIS Data and Standards in Urban Application Domains

GIS has become an important part of many disciplines and supports a vast range of applications. It is used everywhere, from agriculture to public health care. Furthermore, with the advances in technologies, the availability of GIS data and software support has grown exponentially. In this paper, we present the results of our international survey...

Harmonising the OGC Standards for the Built Environment: A CityGML Extension for LandInfra

The relatively new Open Geospatial Consortium (OGC) standard LandInfra documents in its data model land and civil engineering infrastructure features. It has a Geography Markup Language (GML) implementation, OGC InfraGML, which has essentially no software support and is rarely used in practice. In order to share the benefits of LandInfra (and...

Generating 3D city models without elevation data

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...

Meaningful Circular Metabolism

The main products of this graduation are a new pattern language to map difficult/technical interventions in spatial tiles, a GIS model for assessing urban metabolism potentials and restrictions and a new approach for applying urban metabolism measurements on neighbourhood level. A personal motivation for me is the relation between the urban...

Urban Modality: Modelling and evaluating the sustainable mobility of urban areas in the city-region

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...

Automatic enhancement of CityGML LoD2 models with interiors and its usability for net internal area determination

Where Level of Detail (LoD) allow City Geography Markup Language (CityGML) models to be shared over different application domains, only one LoD defines building interiors. As there are potentially numerous applications with a need for building interiors (but not with all the details as defined in LoD4), in order to attain a larger applicability...

MUSIC: GIS based EPM and residual heat potential

We do live in interesting times. Social, political and financial turmoil, peak oil and nuclear accidents all contribute to the realisation that perhaps things need to change in our energy system. Providing the right type of energy at the right place at the right time is of course the answer. As the potential yields of renewable energy sources...

Knowledge-based optimisation of three-dimensional city models for car navigation devices

Three-dimensional maps are deemed better for navigation purposes as they offer a larger number and more realistic navigation cues than two-dimensional maps. Improvements in two key technologies have opened the doors towards utilization of 3D maps for car navigation devices. Advances in data acquisition technologies and data processing methods...

GIS in the World Trade Center response: 10 years after

The World Trade Center attack of 9/11/01 and the response brought major attention to GIS as a valuable tool for supporting emergency management and response. That attention led to the allocation of considerable resources to the enhancement of GIS. This paper is intended to provide a look back at the events prior to and immediately following the...

Measure, understand and improve cities: Visualizing pedestrian flows to improve inner-city quality in Delft using GPS-tracking technology

We all have walked on a street when suddenly someone comes over to you asking for directions. Sometimes, people do not know where they are and they do not know how to reach their destination. They are lost. However, people should not depend on others to find their way. The urban fabric should be legible enough to find one’s way. The problem...
