Digital Earth Australia Intertidal: Continental Elevation and Exposure Maps

10-meter resolution annual elevation and exposure products for Australia's entire intertidal zone, derived from Landsat and Sentinel-2 satellite archives. The dataset, provided by the Australian Ocean Data Network, is designed to map dynamic coastal environments. It was last updated on 2026-06-23.

Use Cases

• Predicting coastal hazard impacts based on baseline elevation data.
• Investigating coastal erosion and sediment transport processes.
• Supporting habitat mapping for ecosystems spanning the terrestrial-marine boundary.
• Characterizing exposure patterns to support migratory species studies.

Strengths

• Continental-scale coverage of Australia's coastline.
• 10-meter spatial resolution for detailed analysis.
• Annual updates enable tracking of dynamic intertidal changes.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment.
