Limitations of Current Methodological Approaches in Composite Spatial Indices of Heat Vulnerability and Implications for Decision Making - Supplementary Materials

Full description

This data package contains supplementary materials for 'Limitations of Current Methodological Approaches in Composite Spatial Indices of Heat Vulnerability and Implications for Decision Making', submitted to the CPGIS Student Paper Competition of the 33rd International Conference on Geoinformatics 2026.

This data package contains the following for each of the three included cities, Adelaide, Cairns, Newcastle:

1. All spatial data inputs per spatial composition framework (Administrative Boundary (AB) and Uniform Grid (UG)) in GeoTIFF and GPKG format; Land Surface Temperature (LST), Population Density (POPD), Normalised Difference Vegetation Index (NDVI), Normalised Difference Built-Up Index (NDBI), Vulnerable Population (POPV), Index of Relative Socio-Economic Disadvantage (IRSD).
2. All sub-indices for each spatial weighting technique and each spatial composition framework in GeoTIFF and GPKG format; Heat Exposure Index (HEI_EQW, HEI_ENW, HEI_PCA), Heat Sensitivity Index (HSI_EQW, HSI_ENW, HSI_PCA), Adapative Capability Index (ACI_EQW, ACI_ENW, ACI_PCA).
3. Final composite urban heat vulnerability index for each spatial weighting technique and each spatial composition framework in GeoTIFF and GPKG format; Urban Heat Vulnerability Index (UHVI_EQW, UHVI_ENW, UHVI_PCA).
4. UG spatial composition technique consensus raster in GeoTIFF format.

The following processing scripts are also included:

1. Google Earth Engine scripts to derive Landsat 9 LST, Sentinel 2 NDVI, Sentinel 2 NDBI, WorldPop total population, and WorldPop vulnerable population in JavaScript format.
2. Jupyter processing notebook for each spatial composition framework to perform normalisation, weighting, generate the sub-indices and resultant composite urban heat vulnerability indices, and perform consensus agreement.
