Sentinel-1 SAR Analysis Ready Data for Australia and Antarctica

Geoscience Australia and CSIRO have developed a CEOS-compliant Sentinel-1 normalised radar backscatter product for Australia and Antarctica, processed using the ISCE-3 framework. The dataset supports monitoring of environmental changes and was evaluated against other processors (SNAP, GAMMA) to ensure quality. The data was last updated on 2026 03 25.

Use Cases

• Monitor flood extent and wetland inundation based on SAR backscatter data.
• Track glacier and sea-ice changes in Antarctica based on cloud-penetrating radar imagery.
• Analyze landcover change and soil moisture based on radar backscatter variations.
• Detect ground subsidence and deformation based on interferometric SAR (InSAR) capabilities mentioned.
• Classify vegetation and monitor coastline changes based on SAR-derived features.

Strengths

• Processor evaluation framework assessed three SAR processors (SNAP, GAMMA, ISCE-3) for quality and interoperability.
• ISCE-3 processor was selected for operational use, providing precise geolocation and radiometric consistency over rugged terrain.
• Product is CEOS-compliant and designed to be analysis-ready, reducing preprocessing burden for users.
• Collaboration with the Polar Geospatial Centre aims to integrate annual Digital Elevation Models for Antarctica to mitigate terrain artifacts.

Limitations

• Description metadata is limited; actual data quality requires manual inspection after download.
• Column-level documentation is absent; field semantics must be inferred after download.
• Row count and file size are unknown, which may limit suitability assessment.
