🌿 KrishiNetra: AI-Powered Precision Agriculture

KrishiNetra is an end-to-end MVP designed to empower farmers and agricultural stakeholders with data-driven insights. Built for the Maharashtra Agrihackathon 2026, it combines satellite imagery analysis with Generative AI to bridge the gap between complex data and actionable farming decisions.

🚀 Key Features

• 🛰️ Satellite NDVI Analysis: Visualizes vegetation health using pre-computed NDVI overlays to identify high-stress zones.
• 📄 AI Document Extraction: Uses Google Gemini to automatically parse and verify complex PDF land records (7/12 extracts).
• 🌾 Crop Prediction: Context-aware crop identification based on geographic coordinates and local lookup data.
• 📍 Interactive Mapping: Built with Streamlit and Folium for a seamless, location-based user experience.
• 🛡️ Stress Detection: Automated calculation of "at-risk" farm areas to prioritize irrigation and intervention.

🤖 Gemini API (Optional)

For document AI, add your key to .env:

GEMINI_API_KEY=your_key_here

Without it, the app uses fallback demo data.
