Sentinel-3 OLCI: Daily True-Color Satellite Imagery for Australian Waters

Sentinel-3 OLCI reduced-resolution daily Level 1B true-colour quicklooks produced by CSIRO under eReefs Phase 5. The imagery is delivered in GeoTIFF format and served via WMS, PNG, and HTML. The dataset was last updated on 2026-06-27.

Use Cases

• Monitoring coastal water color and turbidity based on daily true-color composites.
• Analyzing large-scale ocean surface features based on 1000m-pixel resolution imagery.
• Providing visual context for higher-resolution satellite data analysis based on quicklook products.
• Tracking daily changes in marine environments based on the Level 1B data format.

Strengths

• Data is produced daily, offering frequent temporal coverage.
• Imagery is processed to Level 1B and provided by the authoritative organization CSIRO.
• Available in multiple access formats including WMS for dynamic mapping.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• The pixel size is approximately 1000m, which may limit analysis of fine-grained features.
• Row count and total dataset size are unknown, which may limit suitability assessment.
