TRUST Geospatial Analytics Demonstration Project Singapore Foodscapes: Linking Food Accessibility, Resident Profiles, and Disease Patterns through Geospatial Analysis
4 December 2025
Main Applicant – Dr Alvin Chua, Research Assistant Professor, NUS Cities, College of Design and Engineering, National University of Singapore (NUS)
This project is undertaken by NUS Cities in partnership with HPB and MOH TRUST to assess the possibilities for geospatial analysis using the two national platforms: TRUST and ePlanner X.
Building on existing research questions surfaced by Health Promotion Board (HPB), we will explore how food accessibility and resident profiles in Singapore relate to patterns of acute and chronic disease, using food provision as a policy-relevant case study.
The project will demonstrate how rich geospatial analyses such as mapping travel times to food outlets and reach to affordable and healthy food options by different population segments, as well as the disease prevalence and behavioural outcomes within households may be achieved by combining the data and computational capabilities available on both platforms.
The project will showcase the potential for geospatial analysis enabled by interoperability between the two platforms. We will also identify current limitations and propose practical enhancements to improve the utility for research performers.
