Seamap Australia National Benthic Habitat Layer: Integrated Seafloor Data

A 2026 compilation integrates benthic habitat datasets from research, government, industry, and community sources across Australia. The National Benthic Habitat Layer uniformly classifies these disparate datasets under a national scheme. It is maintained as a 'live' asset by the Australian Ocean Data Network and will continue to develop with new validated data.

Use Cases

• Marine spatial planning based on nationally integrated benthic habitat data.
• Biodiversity assessment based on uniformly classified seafloor habitat types.
• Environmental impact monitoring based on ground-truthed and quality-controlled source datasets.
• Habitat mapping research based on data from satellite, aerial, and acoustic remote sensing.

Strengths

• Integrates data from multiple sectors (research, government, industry, community) into a single national-scale database.
• Employs a uniform national classification scheme implemented as a controlled vocabulary.
• Source datasets must meet five documented acceptance criteria, including quality control and ground-truthing validation.
• Available as a 'live' asset that will continue to develop with improved resolution and currency.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment.
• Data is only available in Geodatabase (.gdb) format as it exceeds Shapefile size limits.
