ISGM-SGC: Standardized Seabed Geomorphology Classification Tool

ISGM-SGC is a standardized classification tool for seabed geomorphology developed by an international working group. The tool assigns five levels of geomorphic attributes and 16 additional interpretation attributes to mapped seabed features. It was created by geoscience agencies from the UK, Norway, Ireland, and Australia to bring consistency to ocean mapping efforts.

Use Cases

• Standardizing seabed feature classification based on a five-level hierarchical framework.
• Attributing geomorphic interpretations to mapped features using the 16 additional descriptive attributes.
• Integrating classified geomorphology data into broader seabed mapping workflows supported by complementary tools.

Strengths

• Implements a standardized, peer-reviewed classification framework developed by an international consortium.
• Tool assigns five levels of classification attributes and 16 additional interpretation 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 contributing national surveys.
