The development of an integrated data repository for urban sustainability analysis is presented; it aims to enhance quantitative analysis of urban sustainability on real statistical data with relevant geographic references. The method is complementary to qualitative and quantitative analyses of sample data, which are the main approaches adopted in conventional urban sustainability analysis. The paper highlights the background and importance of using statistical data for urban planning and

The conceptual model of the integrated data repository is described and the logical integration of statistics from different sources is illustrated. The detailed geospatial conceptual model shows the geospatial classes, main attributes and relationships between these geospatial classes. The paper details the procedure of setting up a server-based database to host both geospatial and non-geospatial data, and uses PostGIS query to interrogate geospatial information in the database, including how to convert the database tables from other formats. A geographic information system (GIS) is introduced as a user-side tool to reveal geospatial and non-geospatial data. Case studies of application of the database for urban sustainability analysis are described. Data maps generated for these case studies can assist planning and design professionals in analysing some urban sustainability issues. Potential applications in various sustainability analyses, barriers and future improvements are also discussed.
