Urban Analytics Lab

Geospatial and 3D urban modelling research group at the National University of Singapore

We are a new interdepartmental multidisciplinary research group focusing on urban data analysis, geographic data science, and 3D city modelling at the National University of Singapore (NUS), the #1 ranked university in Asia and world’s #11 (QS).

Our mission is to leverage on spatially enabled data for urban applications, catalyse the development of 3D geoinformation in the context of smart cities, make sense of big geospatial data and digital twins in the built environment, and cater to disciplines such as architecture, urban planning, and real estate to make informed decisions using 3D city models and urban analytics. We appreciate the importance of geoinformation powering urban informatics, and put a particular focus on the geospatial infrastructure and technology supporting it.

The lab is led by Dr Filip Biljecki, asst prof at NUS School of Design and Environment.

We are involved in several international collaborations such as the World Economic Forum (WEF), the International Society for Photogrammetry and Remote Sensing (ISPRS), and the Open Geospatial Consortium (OGC). On the national level, we have collaborations with Singapore Government agencies and companies.

You are welcome to follow our work through Twitter and our blog.

Our interests and key words: Geographical Information Science (GIS), geospatial machine learning, geographic data science, 3D city modelling / 3D GIS (some people also call them digital twins), 3D urban analytics, spatial data quality and standardisation (CityJSON, CityGML), Volunteered geoinformation (VGI) and OpenStreetMap (OSM), Building Information modelling (BIM), Geospatial data visualisation, 3D underground data modelling, and 3D cadastre.

Leveraging cloud technology for GIS analysis with OpenStreetMap

To increase accessibility, ease of maintenance and enable efficient analysis of OpenStreetMap data, we look at leveraging cloud technology.

Updated plots on the current mobility situation around the world

About two weeks ago, we published an article on how Singapore has responded to the new stringent preventive measures against COVID-19, including a comparison with dozens of other cities around the world.

Welcome, Yoong Shin

We welcome Yoong Shin Chow as new full-time researcher in the group. She will be working on a new project on developing a method to generate 3D city models using geographic data science and machine learning.

Singapore's urban data affirms the compliance with the Circuit Breaker measures

Recent data reveals the way the COVID-19 pandemic unfolded, giving a cross-city understanding of the adherence to social distancing and its impact

OGC considering CityJSON as community standard

CityJSON provides a simplified alternative to the GML encoding of CityGML that is also lightweight and suitable for use on the web and mobile
