Australian Seafloor Bathymetry Models at 30-Meter Resolution

Digital Elevation Models for bathymetry of areas of interest around Australia with a 30-meter resolution. The dataset is provided by the Australian Ocean Data Network and was last updated in July 2026. Bathymetry mapping of the seafloor supports coastal protection, safe shipping navigation, and environmental management.

Use Cases

• Modeling coastal erosion and sediment transport based on high-resolution seafloor topography.
• Planning safe shipping routes and navigation channels based on detailed bathymetric data.
• Assessing marine habitat suitability and health for the Great Barrier Reef based on seafloor structure.
• Supporting offshore infrastructure planning and environmental impact assessments based on seafloor elevation.

Strengths

• 30-meter spatial resolution provides detailed seafloor topography.
• Covers specific, high-interest areas including Northern Australia, the Great Barrier Reef, and Bass Strait.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count and total data size are unknown, which may limit suitability assessment.
• Freshness should be verified as the last update date is in the future (2026-07-09).
