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

EOMAP derived this bathymetry dataset for the Ashmore Reef and Cartier Island Marine Parks in Western Australia from multispectral WorldView-3 satellite data. The data was acquired in 2022-2023 as part of the Australian Government's Marine Parks Grant - Round 3. It provides a high-resolution, georeferenced map of shallow water depths using a physics-based inversion method on reflected sunlight energy.

Use Cases

• Modeling coastal erosion and habitat changes based on high-resolution bathymetric data.
• Supporting marine conservation and management decisions using essential environmental baseline information.
• Conducting ecological research on benthic habitats in shallow water zones.
• Monitoring the impacts of climate change on marine park environments.

Strengths

• Data was derived using a physics-based inversion method on WorldView-3 satellite imagery, suggesting a quantitative approach.
• The dataset provides an environmental baseline for long-term monitoring of two specific Marine Parks in Western Australia.
• It is a high-resolution, georeferenced digital product for shallow water areas.

Limitations

• The dataset is explicitly not to be used for navigational purposes, limiting its application.
• Column-level documentation and sample data are unavailable, making field semantics and structure uncertain.
• The row count and file size are unknown, which complicates suitability assessment.
