Geomorphic Features of Australia's Exclusive Economic Zone, 2006

Geoscience Australia compiled outlines for the maximum extent of geomorphic units within Australia's Exclusive Economic Zone, including offshore island territories. The data set includes unit names, source information, feature codes, province codes, area, and perimeter for each unit. It was updated in October 2006 and is intended as a surrogate for benthic habitats to support seabed bioregionalisation.

Use Cases

• Constructing seabed bioregionalisations based on geomorphic unit outlines.
• Modeling benthic habitats using geomorphic units as spatial surrogates.
• Analyzing the area and perimeter of marine geomorphic features for environmental assessments.
• Mapping the distribution of named geomorphic units and provinces within Australia's EEZ.

Strengths

• Data covers Australia's entire Exclusive Economic Zone, including offshore island territories.
• Includes calculated area and perimeter for each geomorphic unit.
• Accompanied by a formal Geoscience Australia Record (2003/30).

Limitations

• Last updated in October 2006; freshness should be verified for current applications.
• Row count is unknown, which may limit suitability assessment.
• Column-level documentation is absent; field semantics must be inferred after download.
