DEA Coastal Ecosystems

The Digital Earth Australia Coastal Ecosystems product suite is the first national dataset to simultaneously map Australia’s mangrove, saltmarsh, intertidal, and intertidal seagrass ecosystems at 10 m resolution. It uses annual time-series of Sentinel-2 satellite imagery for consistent mapping at a continental scale, produced by Geoscience Australia. The dataset was last updated on 2026-04-30.

Use Cases

• National Environmental Ecosystem Accounts based on mapped coastal ecosystem extents.
• Coastal protection and hazard modelling based on the location and type of protective ecosystems.
• Filling spatial and temporal gaps in higher-resolution expert mapping as a complementary product.
• Monitoring ecological change over time based on annual time-series satellite imagery.

Strengths

• First national dataset to simultaneously map four key coastal ecosystem types for Australia.
• Provides consistent continental-scale mapping at 10-meter resolution using Sentinel-2 imagery.
• Uses annual time-series data, enabling change detection over time.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count and specific file formats are unknown, which may limit suitability assessment.
• Freshness should be verified as the last update timestamp is in the future (2026-04-30).
