ISGM-SGC: Standardized Seabed Geomorphology Classification Tool and Data

The International Seabed Geomorphology Mapping Working Group's Seabed Geomorphology Classifier (ISGM-SGC) is a standardized tool and framework for classifying seabed features. It was developed by geoscience agencies from the United Kingdom, Norway, Ireland, and Australia, including Geoscience Australia. The tool assigns five levels of classification attributes and 16 additional descriptive attributes to mapped seabed features.

Use Cases

• Standardizing seabed feature terminology based on the described five-level classification framework.
• Creating consistent baseline seabed geomorphology maps for ocean resource management.
• Integrating classification outputs with broader seabed morphology mapping workflows mentioned in the description.
• Attributing geomorphic interpretations to mapped features using the 16 additional attributes.

Strengths

• Implements a standardized, two-part classification framework developed by an international working group.
• Tool assigns five levels of 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 and dataset size are unknown, which may limit suitability assessment.
• Data may reflect geographic bias inherent to the contributing agencies' regions.
