Data Sources
- Sentinel-2 satellite imagery (ESA Copernicus)
- Analysis period: June 1 — July 1, 2026
- Cloud cover: 10-15%
- Resolution: 10m (multispectral)
Methodology
- Download Sentinel-2 L2A images for target area
- Pre-process: atmospheric correction, cloud masking
- Extract road mask using OpenStreetMap vectors
- Compare spectral signatures before/after
- Classify change type using trained model
- Calculate confidence based on image quality and change size
Next Steps
- Field verification of detected changes
- Compare with Trafikverket maintenance records
- Refine detection model with ground truth
- Expand to additional road segments
