Interactive Map — Data Pathways
Use the layers and popups to explore urban indicators derived from Earth observation data.
Composite index
Computation: weighted mean of indicators, normalized with the hyperbolic tangent (tanh).
Weights — heat: 3, air: 2.2, UV: 2.5, comfort: 1.2.
Higher values → greener markers (better urban health).
Recommendations for urban planners
- Prioritize urban greening in areas with high heat index.
- Integrate NASA time series (Landsat/MODIS) for continuous monitoring.
- Plan green corridors, shade infrastructure and permeable surfaces to reduce urban heat islands and UV exposure.
Local data: preloaded regions (JSON). Synthetic example data for hackathon purposes.
