DEA Intertidal: Annual 10m Resolution Elevation Maps of Australia's Coastline

Annual continental-scale elevation and exposure products for Australia's intertidal zone, mapped at a 10m resolution. The data is derived from Digital Earth Australia's archive of open-source Landsat and Sentinel-2 satellite data and is provided by the Australian Ocean Data Network. The record was last updated on 2026-06-16.

Use Cases

• Predict coastal hazard impacts based on baseline elevation data mentioned in the description
• Investigate coastal erosion and sediment transport processes based on dynamic topography data
• Support habitat mapping for coastal ecosystems spanning the terrestrial-marine boundary
• Characterize spatio-temporal exposure patterns to aid migratory species studies

Strengths

• Continental-scale coverage of Australia's intertidal zone
• 10-meter spatial resolution derived from Landsat and Sentinel-2 satellite archives
• Annual updates provide a time series for monitoring dynamic coastal changes

Limitations

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