Ashmore Reef and Cartier Island Marine Parks Satellite-Derived Bathymetry (2022-2023)

EOMAP Australia Pty Ltd and EOMAP GmbH & Co.KG derived this bathymetry dataset from multispectral WorldView-3 satellite data for the Australian Government in 2022-2023. The data covers the Ashmore Reef and Cartier Island Marine Parks in Western Australia, providing a high-resolution, georeferenced map of shallow water depths. It serves as an essential environmental baseline for long-term monitoring and management of these marine parks.

Use Cases

• Monitor changes in shallow water habitats based on the high-resolution bathymetry and benthic habitat maps.
• Model coastal erosion or sea-level rise impacts using the georeferenced depth data.
• Support marine navigation planning in shallow zones, though the dataset is not for operational navigational use.
• Conduct ecological research on coral reef or seagrass distribution correlated with water depth.
• Establish environmental baselines for conservation management as mentioned in the description.

Strengths

• Data derived from high-resolution WorldView-3 satellite sensor imagery.
• Processed using a physics-based inversion method for quantitative bathymetric information.
• Provides an essential environmental baseline for long-term monitoring of Marine Parks.
• Acquired under a formal Australian Government Marine Parks Grant in 2022-2023.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count and dataset size are unknown, which may limit suitability assessment.
• Explicitly not to be used for navigational purposes, limiting one potential application.
