ISGM-SGC: Seabed Geomorphology Classification Tool and Framework

International Seabed Geomorphology Mapping Working Group's Seabed Geomorphology Classifier (ISGM-SGC) is a standardized tool for classifying seabed shapes with geomorphic interpretations. Developed by geoscience agencies from the UK, Norway, Ireland, and Australia, it assigns five levels of classification attributes and 16 additional descriptive attributes. The tool is implemented as an Esri ArcGIS Pro Python tool and is designed to integrate with broader seabed mapping workflows.

Use Cases

• Standardizing seabed feature nomenclature across mapping projects based on the described classification framework.
• Attributing geomorphic interpretations to mapped seabed features based on the five-level classification structure.
• Integrating classification outputs with Part 1 seabed morphology mapping workflows mentioned in the description.
• Providing baseline geomorphic information for ocean resource management and environmental planning.

Strengths

• Implements a standardized, two-part 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.
• Data may reflect geographic bias inherent to the collaborating agencies' regions.
