Australia's first national dataset mapping mangrove, saltmarsh, intertidal, and intertidal seagrass ecosystems at continental scale. Produced by Geoscience Australia's Digital Earth Australia program using annual Sentinel-2 satellite imagery at 10-meter resolution. The dataset was last updated on 2026-04-20.
Use Cases
- National Environmental Ecosystem Accounts based on mapped coastal habitat extent.
- State of the Environment reporting based on annual time-series data for monitoring ecological change.
- Complementing higher-resolution expert mapping to fill spatial and temporal gaps.
- Coastal protection and hazard modelling based on the distribution of protective ecosystems like mangroves.
- Integrating with terrestrial and ocean datasets for broader land and marine tenure analysis.
Strengths
- Provides a continental-scale map of Australia's coastal ecosystems.
- Uses 10-meter resolution Sentinel-2 satellite imagery for detailed spatial analysis.
- Offers annual time-series data for consistent, repeatable monitoring.
- Simultaneously maps multiple ecosystem types: mangroves, saltmarsh, intertidal, and intertidal seagrass.
Limitations
- Column-level documentation is absent; field semantics must be inferred after download.
- Row count is unknown, which may limit suitability assessment.
- Freshness should be verified as the last update date is 2026-04-20.
