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 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 geospatial infrastructure and technology in the context of smart cities, and make sense of big geospatial data and digital twins in the built environment to achieve informed decisions.

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, spatial data infrastructure (SDI), 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

3D city models for urban farming site identification in buildings

Studies have suggested that there is farming potential in urban residential buildings. However, these studies are limited in scope, …

Reference study of IFC software support: The GeoBIM benchmark 2019---Part I

Industry Foundation Classes (IFC), the buildingSMART open standard for BIM, is underused with respect to its promising potential, since, according to the experience of practitioners and researchers working with BIM, issues in the standard’s implementation and use prevent its effective use.

Reference study of CityGML software support: The GeoBIM benchmark 2019---Part II

OGC CityGML is an open standard for 3D city models intended to foster interoperability and support various applications. However, through our practical experience and discussions with practitioners, we have noticed several problems related to the implementation of the standard and the use of standardized data.

Extending CityGML for IFC-sourced 3D city models

Differences in the scope and intent of the contrasting IFC and CityGML data formats entail that converting the former to the latter results in loss of information.
