Data related to urban planning is diverse both in terms of sources and formats. To facilitate urban analyses and public access to regulatory information, greater data in-teroperability is needed. Semantic web technologies, which use ontologies to link diverse data, are a promising solution to this problem. In this paper, we describe OntoZoning, an...

Singapore’s urban planning and management is crossdomain in nature and need to be assessed using multi-domain indicators — such as SDGs. However, urban planning processes are often confronted with data interoperability issues. In this paper, we demonstrate how a Semantic Web Technology-based approach combined with a SWOT analysis framework can be u...

This review focuses on recent research literature on the use of Semantic Web Technologies (SWT) in city planning. The review foregrounds representational, evaluative, projective, and synthetical meta-practices as constituent practices of city planning. We structure our review around these four meta-practices that we consider fundamental to those pr...

In Singapore, decision-makers from multiple ministries and government agencies participate in urban planning and management. This often results in siloed datasets, different data formats and domain specific software: a lack of interoperability that hinders the integration of (big) data in planning. Semantic Web Technology (SWT) can help to solve da...

Abstract Affordable housing with fair and transparent land-allocation measures is a challenge for many countries. The Sultanate of Oman solves this issue by means of land-allocation lotteries in which male and female citizens can participate in order to win a parcel of a new housing area. Besides supporting those in financial need the lottery aims...

Article
Urbanisation in Oman started shortly after 1970. The process of urbanisation changed the land-use and settlement patterns in Oman and in particular in Muscat Capital Area. Modern urban geography and urban planning in Oman emerged in the 1980s when the ‘rational’ Llewelyn-Davies plan of 1981 became the guiding planning framework. The main conceptual...

This paper presents a method and case study to visualize the urban stock of materials and its availability for use in building future cities. Re-using material from existing buildings for new buildings can be seen as a source for construction materials in times of depleting natural resources. The authors explain the concept of "urban mining" and th...

According to the United Nations, two-thirds of the world population will live in urban areas in the near future—that is in cities and urban regions.How will the other third live? This question alone suggests a simplistic dichotomy between urban and rural spaces that no longer exists. Alongside—not opposite—the transformation and drastic expansion o...

Project
Global construction material demand has more than doubled in the last 20 years and is projected to increase further. The resulting substantial increase in grey energy and material-​related environmental impact is more than the planet can sustainably bear. Therefore, a transition to a circular economy, in which used materials may become valuable resources for a new production cycle, is urgently needed. This module aims to develop integrated frameworks and tools based on advanced digital technology for informing the design of circular buildings and deploying more effective resource solutions. It addresses the questions of which contributions future circular cities can make to lower adverse environmental impacts and how to derive tailored, site-​specific system solutions for sustainable housing. https://fcl.ethz.ch/research/circular-future-cities.html
Project
This research aims to harness rapidly growing and diversifying data streams to improve the planning and design of cities. It will do so by developing an innovative digital platform, known as the Cities Knowledge Graph (CKG), designed to combine data and share knowledge about cities, and to inject new precision and responsiveness to static instruments of planning, such as the city master-​plan. Cities Knowledge Graph is an Intra-​CREATE collaborative project under the urban systems theme. The project brings together expertise from Cambridge CARES (the Cambridge Centre for Advanced Research and Education in Singapore, established by the University of Cambridge) as the host institution of the project, and SEC (the Singapore-​ETH Centre, established by ETH Zürich). The team is led by principal investigators from the University of Cambridge and ETH Zürich. This research is supported by the National Research Foundation, Prime Minister’s Office, Singapore under its Campus for Research Excellence and Technological Enterprise (CREATE) programme. https://fcl.ethz.ch/research/research-projects/cities-knowledge-graph.html https://www.cares.cam.ac.uk/research/cities/
