Satellite-Derived Bathymetry and Seafloor Habitat Maps for Cocos (Keeling) Islands

Satellite-derived bathymetry and seafloor habitat classification maps for the shallow waters of the Cocos (Keeling) Islands Marine Park. The data was processed by EOMAP using proprietary software and a physics-based inversion method, providing a 2-meter horizontal spatial resolution for depths up to 25 meters. This project was conducted for Parks Australia - Indian Oceans Territory to establish an environmental baseline for long-term monitoring and management.

Use Cases

• Modeling coastal erosion and sediment transport based on high-resolution bathymetry.
• Classifying and monitoring benthic habitats for conservation planning based on spectral characteristics.
• Supporting ecological research on coral reef and seagrass distribution using seafloor reflectance data.
• Assessing climate change impacts on shallow marine environments using standardized geospatial layers.

Strengths

• High 2-meter horizontal spatial resolution for detailed analysis.
• Covers shallow waters from approximately 0 to 25 meters depth.
• Based on a physics-based inversion method of the radiative transfer equation.

Limitations

• Description metadata is limited; actual data quality requires manual inspection after download.
• Column-level documentation is absent; field semantics must be inferred after download.
• Data may reflect geographic bias inherent to data_gov_au, being specific to a single marine park.
