💡 How GreenMap Works
GreenMap uses real-time Earth observation data to monitor urban greenness, heat, rainfall, and climate anomalies. Here's how each layer empowers communities and planners:
🌳 NDVI – Vegetation Health
Tracks how green and healthy plant cover is across Nairobi. Crucial for identifying urban greening, deforestation, and restoration zones.
🔥 LST – Land Surface Temperature
Maps urban heat islands by showing surface temperature variations. Helps pinpoint overheated zones and support climate adaptation efforts.
🌧 Rainfall Monitoring
Compares current rainfall to historical trends. Useful for assessing water availability, drought patterns, and seasonal shifts.
📊 Anomaly Detection
Combines NDVI and rainfall anomalies to detect unusual greenness or dryness. Helps track early signs of degradation or recovery.
📊 SDG Tracker - Progress at a glance
Live indicators mapped to city-relevant SDG themes. Values below are populated from the backend when available.
Shows % area with tree canopy (NDVI-based). Higher is better.
UHI intensity (°C) - difference between urban and nearby rural LST. Hotspots show number or area of 1km pixels above threshold.
Average NDVI across the city (0 to 1). Higher indicates healthier vegetation.
