Digital Earth Australia Intertidal: Annual 10m Resolution Elevation and Exposure Maps

Digital Earth Australia Intertidal provides annual continental-scale elevation and exposure products for Australia's intertidal zone. The data is mapped at a 10-meter resolution from Digital Earth Australia's archive of open-source Landsat and Sentinel-2 satellite data. It is hosted by the Australian Ocean Data Network and was last updated in June 2026.

Use Cases

• Integrating elevation data with topographic and bathymetric data to map the coastal zone seamlessly.
• Predicting the impact of coastal hazards like storm surges and sea-level rise based on baseline elevation data.
• Investigating coastal erosion and sediment transport processes using annual exposure patterns.
• Supporting habitat mapping and modelling for ecosystems across the terrestrial-marine boundary.
• Characterizing spatio-temporal exposure patterns to support migratory species studies.

Strengths

• Provides continental-scale coverage of Australia's intertidal zone.
• Offers a 10-meter spatial resolution for detailed analysis.
• Derived from the long-term, open-source Landsat and Sentinel-2 satellite archive.
• Produces annual elevation and exposure products to monitor dynamic changes.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count and total data size are unknown, which may limit suitability assessment.
• Data may reflect geographic bias inherent to its focus on Australia.
