How to use

Use the layer control (top-right) to compare surface heat patterns with land cover and urban structure. Toggle a few layers at a time for clarity — each active layer's color scale appears at the bottom. Hover the ? next to a layer to see its description (you can move the pointer into the tooltip to scroll long text).

UHI Anomaly: warmer/cooler than a rural reference (ΔT).
Gi*: statistically significant hot/cold clusters.
UHI Zones: clustered categories of surface temperature.
