Digital Earth Australia Intertidal: Annual 10m Elevation Maps of Australia's Coast

Annual continental-scale elevation and exposure data for Australia's intertidal zone, mapped at a 10-meter resolution. The product suite is derived from Digital Earth Australia's archive of open-source Landsat and Sentinel-2 satellite data and is produced by Geoscience Australia. The dataset was last updated on 2026-03-25.

Use Cases

• Integrating elevation data with topographic and bathymetric data to map the coastal zone seamlessly, as mentioned in the description.
• Predicting the impact of coastal hazards like storm surges and future sea-level rise using baseline elevation data.
• Investigating coastal erosion and sediment transport processes across dynamic intertidal regions.
• Supporting habitat mapping and modeling for coastal ecosystems spanning the terrestrial-marine boundary.
• Characterizing spatio-temporal exposure patterns to support migratory species studies and conservation efforts.

Strengths

• Provides continental-scale coverage for Australia's entire intertidal zone.
• Offers annual time-series data at a 10-meter spatial resolution.
• Derived from a long-term archive of open-source Landsat and Sentinel-2 satellite imagery.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count and dataset size are unknown, which may limit suitability assessment.
• Freshness should be verified as the last metadata update was 2026-03-25.
