Australia's continental coastline is covered by high and low tide mosaics generated from satellite imagery. The dataset likely contains pixel-based surface reflectance composites created using a multi-resolution tidal model and a Voronoi mesh to account for tidal dynamics. The data was produced by researchers including Sagar, Phillips, Bala, Roberts, and Lymburner, with a related publication in the journal Remote Sensing in 2018.
Use Cases
- Coastal change detection based on tidally constrained composite imagery.
- Monitoring tidal influences on coastal environments based on high and low tide mosaics.
- Analyzing spatial variation in tidal dynamics based on the use of a Voronoi mesh.
- Further interpretation and analysis of coastal spectra based on preserved band relationships within modelled spectra.
Strengths
- Covers the continental-scale Australian coastline.
- Provides composites for both high and low tide states.
- Method preserves band relationships within modelled spectra at each pixel.
Limitations
- Column-level documentation is absent; field semantics must be inferred after download.
- Row count is unknown, which may limit suitability assessment.
- Description metadata is limited; actual data quality requires manual inspection after download.
