Digital Earth Australia Intertidal provides annual continental-scale elevation and exposure products for Australia's intertidal zone. The data is derived from Landsat and Sentinel-2 satellite imagery and is mapped at a 10-meter resolution. It is hosted by the Australian Ocean Data Network and was last updated in June 2026.
Use Cases
- Predicting coastal hazard impacts based on baseline elevation data.
- Investigating coastal erosion and sediment transport processes based on dynamic topography.
- Supporting habitat mapping for coastal ecosystems spanning terrestrial to marine boundaries.
- Characterizing spatio-temporal exposure patterns to support migratory species studies.
Strengths
- Continental-scale coverage of Australia's intertidal zone.
- Annual products derived from open-source Landsat and Sentinel-2 satellite data.
- 10-meter spatial resolution for detailed analysis.
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 is unknown, which may limit suitability assessment.
