Urban Heat Island vulnerability mapping using advanced GIS data and tools

Urban Heat Island (UHI) is a phenomenon that can cause hotspots in city areas due to dense, impervious infrastructure and minimal vegetation cover. UHI may become worse extreme heat events are already affecting many regions across the globe increased frequent hot extremes, human-induced warming cities, rapidly growing urbanization, as documented by latest IPCC report 2021. In seeking support designers, planners, decision-makers developing implementing adaptation strategies measures make our cities sustainable resilient, reliable projections modelling required. this study, we modelled vulnerability using high-resolution spatial data, advanced geospatial tools, socio-demographic data. This modified approach drew upon index maps 20 select customized indicators of exposure, population sensitivity, mobility/adaptive capacity. The were Delphi evaluated weighted, methodology was applied against City Greater Geelong municipality Australia. resulting indicated significant high building density, commercial/industrial zones, newly constructed sites, zones with low urban green infrastructure. These maps, combination selected indicators, highlighted areal concentration risk vulnerable locations for sensitive human population. primarily concentrated density areas, which seen through correlation curves. However, showed weak correlation, per meshblock strong measurements. study provides comprehensive analysis mapping assessment GIS data advancement major local government area concludes has replicability incomparable geographical regions.
