🌍 GeoGini — Explore Earth Intelligently

GeoGini is an interactive geospatial intelligence platform powered by Google Earth Engine, satellite data, and AI.
Draw regions on the map, extract real metrics like NDVI, Land Surface Temperature, Rainfall, and get AI-generated insights based on both data and uploaded images.

🛠️ Stack Used

Tech	Description
🌐 Frontend	React + Vite + Tailwind + ShadCN UI, deployed on Netlify.
🌎 GEE	Google Earth Engine for real-time metric data
🧠 AI	Hugging Face Inference API (Meta Llama model)

💡 How It Works

1. Select a region on the map — the app captures it via GEE's drawingTools.
2. Metrics are computed using reduceRegion and sent via postMessage.
3. React frontend receives metrics, displays them, and auto-fills the AI form.
4. You upload an image or just type a prompt — and get a Meta Llama-generated response.
5. Time-series modal shows a summary of average values across a year.

🧪 Try It Yourself

✅ Open https://geogini.netlify.app
✅ Draw a rectangle on the map
✅ Wait for metrics to load
✅ Ask questions like:

"Explain the land use and vegetation in this region."
"How does the rainfall affect habitability here?"

Or upload an image and ask:

"What environmental challenges can you guess from this?"
