⛵ sentinel2-xcube-boat-detection
Github repository to detect and count boat traffic on Euro Data Cube using ESA's Sentinel-2 imagery
Setup with EDC
- Create an account on Mapbox and Euro Data Cube
- Clone this repository in a Jupyter Lab environment (Python 3.6+) on Euro Data Cube
- Edit Mapbox and Sentinel Hub token in a .env file
- Run
pip install -r requirements.txt
Pipeline
1. 🛰️ Download data
Sentinel 2 L1C bands B03, B08 and CLP in areas of interest (e.g., Ports, Straits, MPA), saved under data/aoi.json
Annotations/Labels: 1 squared km chips with boat counts
2. ☄️ Preprocess
Informative snaps: Nans and cloudy images (from CLP) removed
Background NDWI: image computed by fusion over time (max operation over NDWI band)
3. 🔭 Detect and count boat traffic
Output: Boat traffic presence/density heatmap (10-100m spatial resolution) & global count
Hidden states: Pixels' embeddings, Patches' encodings
Input (3 channels): NIR band, Background NDWI and CLP band
