Australian Coastal Surface Reflectance Composites Using Tidal Model

Australian continental-scale pixel composites of surface reflectance for coastal and estuarine environments, corrected for tidal influences using a multi-resolution tidal model. The dataset includes high and low tide mosaics of the Australian coastline, generated by researchers from the Australian Ocean Data Network and published in 2018.

Use Cases

• Coastal change detection by analyzing pixel reflectance values in high and low tide composite images.
• Monitoring estuarine environments using the tidally constrained composites to track sediment plumes or vegetation changes.
• Validating tidal models by comparing the spatial variation in tidal dynamics captured by the Voronoi mesh against ground truth data.
• Assessing band relationships within the modelled spectra at each pixel for spectral unmixing or water quality parameter retrieval.

Strengths

• Continental-scale coverage of the Australian coastline.
• Composites generated for specific tidal states (high and low tide).
• Method preserves band relationships within spectra at each pixel.

Limitations

• Specific row count, column count, and temporal resolution are unknown.
• Dataset appears focused on a proof-of-concept study from 2018, potentially lacking regular updates.
• Utility may be limited to applications specifically requiring tide-normalized reflectance, not raw satellite data.
