Sentinel-1 Ground Range Detected (GRD)
Level-1 Ground Range Detected (GRD) products consist of focused SAR data that has been detected, multi-looked and projected to ground range using the Earth ellipsoid model WGS84. The ellipsoid projection of the GRD products is corrected using the terrain height specified in the product general annotation. The terrain height used varies in azimuth and it is constant in range (For IW/EW modes only the terrain height of first subswath is considered)

Useful for
- Use cases llm-inferred
- Flood extent mapping from SAR after storm events for FRA evidence · Surface water change detection for drainage or wetland baselines, independent of cloud cover · Land cover change screening for BNG habitat baselines · Terrain-corrected SAR backscatter inputs for GIS-based site screening
- Audience llm-inferred
- flood consultants · hydrologists · GIS analysts · ecologists
Limitations
- Constraints llm-inferred
- ENTRY auth field is null, but DOCS list OIDC and S3 authentication for asset access · CREODIAS S3 storage is requester-pays · Licence is 'other'; check the Copernicus legal notice before commercial use · No spatial resolution stated in DOCS · Level-1 GRD is radiometric SAR data, not analysis-ready; needs SAR processing expertise · Sentinel-1 only; no optical or multispectral bands
