Satellite-Derived Bathymetry and Seafloor Habitat Classification Mapping of Christmas Isla

Satellite-derived bathymetry and seafloor habitat classification maps for the shallow waters of Christmas Island Marine Park, processed at a 2-meter horizontal spatial resolution. The data was generated by Parks Australia using EOMAP's Watcor-X software and multispectral satellite imagery. 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 coral reef or seagrass habitats based on classified seafloor habitat maps.
• Planning marine conservation zones based on detailed benthic habitat classification.
• Assessing navigation safety and underwater hazards based on satellite-derived bathymetry.
• Studying the impacts of climate change on shallow marine ecosystems based on time-series comparisons of habitat maps.

Strengths

• 2-meter horizontal spatial resolution provides detailed mapping for shallow coastal areas.
• Data covers the shallow water zone from approximately 0 to 25 meters depth.
• Processing used a physics-based inversion method (Watcor-X) for bathymetry and object-based classification for habitats.
• Data is georeferenced and provided in multiple formats including WMS for direct web access.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count and total dataset size are unknown, which may limit suitability assessment.
• Freshness should be verified as the last updated date is in the future (2026-06-04).
