Christmas Island Marine Park Satellite-Derived Bathymetry and Seafloor Habitat Maps

Satellite-derived bathymetry and seafloor habitat maps at 2-meter horizontal resolution for the shallow waters of Christmas Island Marine Park. The data was processed by EOMAP using their proprietary Watcor-X software and a physics-based inversion method. These geospatial layers provide a baseline for monitoring and managing the Indian Ocean Territories Marine Parks.

Use Cases

• Modeling coastal erosion and sediment transport based on high-resolution bathymetry.
• Classifying and monitoring benthic habitats for conservation planning based on spectral seafloor reflectance.
• Assessing climate change impacts on shallow marine ecosystems based on the environmental baseline data.
• Supporting marine spatial planning and safety-at-sea navigation (non-navigational use) based on detailed depth maps.

Strengths

• 2-meter horizontal spatial resolution provides detailed mapping.
• Covers shallow waters from approximately 0 to 25 meters depth.
• Processed using a proprietary physics-based inversion method (Watcor-X) for bathymetry.
• Provides a digital, georeferenced baseline for long-term monitoring.

Limitations

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