✨ Executive Feature Highlights

1. 🧠 Machine Learning Risk Intelligence

• 0.904 ROC-AUC Accuracy: Ensemble classification of rainfall risk (LOW, MODERATE, HIGH, CRITICAL) trained on historical monsoon data.
• Strict Mathematical Synchronization: Probability and risk categories dynamically scale with precipitation volume for 100% card consistency across all user input locations.

2. 🏔️ 3D Digital Twin DEM Elevation Profile

• Native Three.js WebGL Engine rendering 30m Digital Elevation Model cross-sections.
• Calculates slope gradients ($3.4^\circ$), river basin terrain, and dynamic water accumulation surge levels ($49.5\text{m}$).

3. 🤖 Conversational Multi-City AI Assistant

• Natural language query interface supporting prompts like "for Patna", "for Motihari", "for Ranchi".
• Performs entity extraction, fetches live satellite weather data, and triggers 1-click interactive map camera flights.

4. 🚁 Autonomous UAV Drone Reconnaissance & NDMA PDF Exporter

• Low-altitude 4K Thermal IR patrol stream operating below cloud cover at 120m altitude.
• Real-time aerial damage scan of bridges, power substations, and submerged highways with 1-click official NDMA PDF Report Export.

5. 🧭 NDRF Safe Evacuation Pathfinder

• Dynamic GPS safe route dispatch to nearby emergency relief shelters and sports complexes.
• 1-click emergency escalation to NDRF Headquarters (1078) and State Emergency Relief Cell (1070).
