Cocos (Keeling) Islands Marine Park Satellite-Derived Bathymetry and Seafloor Habitat Map

Cocos (Keeling) Islands Marine Park shallow waters were mapped at 2-meter horizontal spatial resolution. The dataset provides satellite-derived bathymetry and seafloor habitat classification for depths between 0 and 25 meters, processed using EOMAP's proprietary Watcor-X software. These geospatial layers were created by Geoscience Australia Data to serve as an environmental baseline for long-term monitoring and management.

Use Cases

• Modeling coastal erosion and sediment transport based on high-resolution bathymetry.
• Monitoring changes in major seafloor habitat types based on spectral classification.
• Supporting marine park management and conservation planning based on baseline habitat maps.
• Conducting ecological research on coral reef and seagrass distribution based on seafloor reflectance data.

Strengths

• 2-meter horizontal spatial resolution provides detailed mapping of shallow waters.
• Bathymetry is derived using a physics-based inversion method of the radiative transfer equation.
• Seafloor habitat classification is based on object-based analysis of multispectral satellite imagery.
• Data provides a standardized reflectance surface of the subsurface and seafloor for the marine park.

Limitations

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