Zagreb Urban Heat Island Map

To support innovation work on heat islands, we developed an urban heat island analysis for the City of Zagreb that goes beyond mapping temperatures — it connects heat exposure with who lives where, making it actionable for planners, researchers, and policymakers.

The work combines satellite-derived land-surface temperature data with census demographics, processed and published as an interactive web map.

• City-wide Heat Analysis: Urban heat island mapping from satellite data, identifying hot and cold spots and temperature zones across the city.
• Interactive Web Map: Layered map interface where users can turn data layers on and off — heat zones, population density, age groups, and vulnerability indices.
• Neighbourhood-level Views: Analysis aligned with official Zagreb city boundaries for planning-compatible outputs.
• Census Overlays: Population density and age structure (children, working age, elderly) integrated at the neighbourhood level.
• Vulnerability Layers: Composite indices that highlight where high temperatures overlap with older or younger populations — making social exposure visible.
• Higher-resolution Detail: Fine-scale heat mapping where high-resolution satellite scenes are available.
• Validation: Methods cross-referenced against weather station and reference climate data for reliability.
• Research-grade Methodology: Analytical approach suitable for academic publication and policy use.

The map is publicly deployed for sharing with City of Zagreb stakeholders and decision-makers.
