Geomorphic Units Of Australia's Exclusive Economic Zone

Geomorphic Features 2006 provides polygon outlines for geomorphic units across Australia's Exclusive Economic Zone and offshore island territories. Compiled by Geoscience Australia, this dataset serves as a surrogate for benthic habitats to support environmental management of ocean resources. The data was updated in October 2006 and is accompanied by Geoscience Australia Record 2003/30.

Use Cases

• Map benthic habitat surrogates using the geomorphic unit outlines and their associated feature codes.
• Calculate seabed province areas for bioregionalisation using the polygon area and perimeter attributes.
• Analyze the distribution of specific geomorphic features (e.g., canyons, plateaus) by querying the unit name and feature code fields.
• Integrate geomorphic unit data with other marine datasets using the provided province codes for regional analysis.

Strengths

• Covers the full spatial extent of Australia's Exclusive Economic Zone and offshore islands.
• Includes specific attributes like unit name, feature code, province code, area, and perimeter for analysis.
• Associated with a formal technical record (Geoscience Australia Record 2003/30).

Limitations

• Data currency is limited, with a last noted update in October 2006.
• Sample data and exact row counts are unavailable, preventing assessment of dataset granularity.
• The exclusion of the Australian Antarctic Territory limits pan-Australian marine analysis.
