EOMAP_20220329.0835 Christmas Island Marine Park Satellite-Derived Bathymetry Acquisition

A 2022 acquisition mapped Satellite-derived Bathymetry and seafloor habitats at 2-meter horizontal spatial resolution for shallow waters (0-25 meters) of Christmas Island Marine Park. The data was processed by EOMAP using proprietary software and a physics-based inversion method. These geospatial layers provide an environmental baseline for monitoring and managing the Indian Oceans Territory 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.
• Supporting ecological research on coral reef or seagrass distribution using habitat type maps.
• Informing marine park zoning and management decisions based on baseline environmental data.

Strengths

• High 2-meter horizontal spatial resolution for detailed analysis.
• Covers a defined depth range of approximately 0 to 25 meters in shallow waters.
• Based on a physics-based inversion method for bathymetry derivation.
• Provides standardized reflectance surfaces of the subsurface and seafloor.

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.
• Spatial coverage is limited to the Christmas Island Marine Park.
