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

Cocos (Keeling) Islands Marine Park shallow waters (0-25 m) are mapped at 2-meter horizontal resolution. The dataset contains satellite-derived bathymetry and seafloor habitat classification, processed using EOMAP's Watcor-X algorithm and object-based classification. These geospatial layers provide a baseline for long-term monitoring and management of the Indian Ocean Territories Marine Parks.

Use Cases

• Modeling coastal erosion and sediment transport based on high-resolution bathymetry.
• Monitoring changes in benthic habitats for conservation management based on seafloor classification.
• Supporting marine navigation and safety planning based on detailed bathymetric maps.
• Assessing climate change impacts on shallow marine ecosystems based on the environmental baseline data.

Strengths

• 2-meter horizontal spatial resolution provides detailed mapping.
• Covers shallow waters from approximately 0 to 25 meters depth.
• Data processed using a proprietary physics-based inversion method (Watcor-X).
• Provides a standardized reflectance surface of the subsurface and seafloor.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Data is provided in PNG format, which may limit direct geospatial analysis without georeferencing.
• Row count is unknown, which may limit suitability assessment.
