Oil Slick Detection Filter

Oil Slick Detection Filter detects oil slicks on the sea with SAR images from Sentinel-1.

This filter can distinguish between oil slicks and other sea surfaces with high accuracy, which is difficult to detect by non-specialists.

By using the difference in radio wave reflection characteristics of the water surface, the algorithm automatically detects oil slick from a single SAR image. This block uses a deep learning algorithm to achieve overwhelming performances.

Supported Workflow

Sentinel-1 L1 GRD (SAFE) -> SNAP Polarimetric Processing Sentinel-1 -> Oil Slick Detection Filter

The following parameters need to be set:

• "clip_to_aoi": true
• "tcorrection": true
• "linear_to_db": false
• "polarisations": [“VV”]
• "speckle_filter": false
