ISGM-SGC: Seabed Geomorphology Classification Tool and Framework

Geoscience Australia and international partners developed a standardized tool for classifying seabed geomorphic features. The International Seabed Geomorphology Mapping Working Group's classifier implements a two-part mapping approach, assigning five levels of classification attributes and 16 additional descriptive attributes. The tool is designed as an Esri ArcGIS Pro Python tool to bring consistency to seabed mapping efforts.

Use Cases

• Standardizing seabed feature terminology based on the described five-level classification framework.
• Creating consistent baseline geomorphology maps for ocean planning based on the standardized nomenclature.
• Integrating geomorphic classification into broader seabed mapping workflows as mentioned in the description.

Strengths

• Implements a standardized, peer-reviewed classification framework developed by an international working group.
• Tool assigns five levels of geomorphology classification attributes and 16 additional descriptive attributes.
• Includes tutorials, a user guide, and sampled data for application examples.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment.
• Description metadata is limited; actual data quality requires manual inspection after download.
