DEA Coastal Ecosystems: Australia's Mangroves, Saltmarshes, and Seagrass at 10m Resolution

Australia's first national dataset simultaneously mapping mangrove, saltmarsh, intertidal, and intertidal seagrass ecosystems at a continental scale. The product suite uses annual time-series of Sentinel-2 satellite imagery to provide consistent 10-meter resolution mapping. It is provided by the Australian Ocean Data Network via Digital Earth Australia.

Use Cases

• Generate National Environmental Ecosystem Accounts based on annual coastal ecosystem extents.
• Support State of the Environment reporting based on consistent, continental-scale mapping.
• Fill spatial and temporal gaps in higher-resolution expert mapping (e.g., from drones) based on the satellite-derived annual time-series.
• Model coastal protection and hazards based on mapped ecosystem locations and extents.

Strengths

• First national dataset to simultaneously map four key Australian coastal ecosystems.
• Provides 10-meter resolution mapping derived from Sentinel-2 satellite imagery.
• Uses annual time-series for consistent continental-scale monitoring.

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; last metadata update was 2026-06-23.
