# AlgaeGuard — Autonomous HAB Detection from Orbit
Fine-tuned **LFM2.5-VL-450M** on Sentinel-2 NDCI imagery for sub-90-minute
Harmful Algal Bloom alerts — directly from the satellite, before the crisis hits.
## Features
- **Live Demo** — 218 real Sentinel-2 observations across 6 water bodies
- **Historical HAB Timeline** — interactive bloom severity charts (2022–2024)
- **Custom Inference** — upload any NDCI colormap or fetch live from SimSat
- **ZeroGPU inference** — ~4s per assessment on GPU
## Optional: Live Satellite Fetch
Set the `SIMSAT_API_URL` Space secret to enable live Sentinel-2 data fetch
for any coordinates on Earth via [SimSat](https://github.com/debpks/SimSat).
