A continental-scale dataset of pixel-based surface reflectance composites for Australia's dynamic coastal and estuarine environments. The composites are generated using a multi-resolution tidal model based on a Voronoi mesh to account for tidal influences, enabling robust analysis of coastal changes. This dataset is associated with a 2018 research paper published in the journal Remote Sensing.
Use Cases
- Coastal change detection based on tidally constrained composites mentioned in the description
- Monitoring of estuarine environments using the spatial variation in tidal dynamics captured by the model
- Analysis of band relationships within modelled spectra at each pixel for further interpretation
- Creation of continental-scale mosaics of coastline imagery at specific tidal states
Strengths
- Composites are generated at a continental scale for the Australian coastline
- Method specifically addresses tidal confounding in dynamic coastal environments
- Case studies demonstrate application for a range of coastal monitoring tasks
Limitations
- Column-level documentation is absent; field semantics must be inferred after download
- Row count is unknown, which may limit suitability assessment
- Data may reflect geographic bias inherent to data_gov_au, focusing on Australia
