Urban Heat Vulnerability Indices for Three Australian Cities

289.8 MB of supplementary materials supports research on composite spatial indices for heat vulnerability. The package contains geospatial data inputs, calculated sub-indices, and final composite indices for Adelaide, Cairns, and Newcastle. Ryan Turner authored this data, last updated in April 2026.

Use Cases

• Compare Urban Heat Vulnerability Index (UHVI) outputs generated via Equal Weighting (EQW), Entropy Weighting (ENW), and Principal Component Analysis (PCA) methods.
• Analyze relationships between sub-indices like Heat Exposure (HEI), Heat Sensitivity (HSI), and Adaptive Capability (ACI) against raw inputs such as Land Surface Temperature (LST) and Population Density (POPD).
• Validate spatial composition frameworks by comparing results from Administrative Boundary (AB) and Uniform Grid (UG) data structures.
• Reproduce index calculations using the provided Jupyter notebooks which detail normalization and weighting steps for the listed variables.
• Assess consensus agreement for the UG framework using the included consensus raster GeoTIFF file.

Strengths

• Provides data for three distinct cities (Adelaide, Cairns, Newcastle) enabling comparative analysis.
• Includes both raw input data (e.g., LST, NDVI, NDBI, POPD) and multiple derived index layers across two spatial frameworks.
• Offers full processing scripts in Google Earth Engine (JavaScript) and Jupyter notebooks for transparency and reproducibility.

Limitations

• Sample size is limited to three cities, restricting generalizability of findings to other urban contexts.
• Temporal coverage for the satellite-derived inputs (Landsat 9, Sentinel 2) is not specified, potentially affecting recency.
• Row counts and specific spatial resolutions for the GeoTIFF and GPKG files are unknown.
