Modified Copernicus Sentinel-1 data processed into a normalized radar backscatter product on a linear scale in decibels. The dataset was created by the UK's Department for Environment, Food and Rural Affairs (Defra) and Joint Nature Conservation Committee (JNCC) to provide cost-effective, high-quality Analysis Ready Data. Products are Ground-Range Detected (GRD) Interferometric Wide-swath (IW) in dual VV+VH polarisation mode.
Use Cases
- Land cover and land use change detection based on normalized radar backscatter values.
- Environmental monitoring and disaster response analysis based on dual-polarization Sentinel-1 data.
- Agricultural and forestry applications leveraging the processed, analysis-ready format of the imagery.
Strengths
- Data is processed to an Analysis Ready Data (ARD) standard, reducing preprocessing burden for users.
- Uses dual VV+VH polarisation from Sentinel-1's Interferometric Wide-swath mode, providing two complementary data channels.
- Processed by two UK government bodies (Defra and JNCC) using a common specification for complementary outputs.
Limitations
- Row count, file formats, and column-level documentation are unknown, limiting suitability assessment.
- Scenes processed before July 2021 have a strip of data clipped from the northern edge to remove a processing artefact.
- Last update date is unknown; freshness unverified.
