Digital Earth Australia's Coastal Ecosystems product suite provides annual, continental-scale maps of mangrove, saltmarsh, intertidal, and intertidal seagrass ecosystems. The dataset is derived from Sentinel-2 satellite imagery at 10-meter resolution and is hosted by the Australian Ocean Data Network. The metadata was last updated on April 16, 2026.
Use Cases
- Generate National Environmental Ecosystem Accounts based on mapped ecosystem extents.
- Support State of the Environment reporting by monitoring annual changes in coastal habitats.
- Fill spatial and temporal gaps in higher-resolution expert mapping by providing consistent continental-scale data.
- Model coastal protection and hazards by integrating ecosystem maps with other terrestrial and ocean datasets.
Strengths
- Provides the first national dataset simultaneously mapping four key coastal ecosystems.
- Offers consistent continental-scale mapping at 10-meter resolution.
- Uses annual time-series of Sentinel-2 imagery for repeatable analysis.
Limitations
- Column-level documentation is absent; field semantics must be inferred after download.
- Row count is unknown, which may limit suitability assessment.
