Urban Analytics Lab

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

We are hiring postdoctoral research fellows to join our growing research group in 2021.

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 2021).

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.

The research group is led by Dr Filip Biljecki, presidential young professor at the 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, other research groups, 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.

New paper: Visualising detailed CityGML and ADE at the building scale

There is an increasing activity in developing workflows and implementations to convert BIM data into CityGML. However, there are still not many platforms that are suitable to view and interact with the detailed information stored as a result of such conversions, especially if an Application Domain Extension (ADE) is involved to support additional information.
