National Coastal Geomorphic Classification of Australia

Australia's coastal zone is mapped in a nationally consistent geomorphic classification. The dataset represents the first phase of a national-scale map, created by reclassifying pre-existing state-wide GIS datasets into a unified scheme developed by Geoscience Australia. It is structured as a geodatabase containing feature datasets for each state.

Use Cases

• Coastal vulnerability assessment based on geomorphic unit classification.
• National environmental reporting using a standardized coastal landform inventory.
• GIS analysis for coastal zone management planning across state boundaries.
• Validating regional geomorphological models against a national classification framework.

Strengths

• Provides a nationally consistent classification scheme for the entire Australian coastline.
• Integrates pre-existing datasets from multiple government levels (local, state, federal).
• Structured as a geodatabase, which likely contains detailed vector feature datasets.

Limitations

• Metadata is incomplete; specific column names, row counts, file sizes, and license information are not provided.
• The dataset is described as 'Phase one,' suggesting coverage or classification detail may be partial.
• Conflicting 'last updated' dates (2026-04-30 and 2026-03-07) create uncertainty about version freshness.
