ISGM-SGC: Seabed Geomorphology Classification Tool and Framework

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

Use Cases

• Standardizing seabed feature terminology based on the described two-part classification framework.
• Creating consistent seabed geomorphology maps for ocean economy stakeholders based on the described mapping approach.
• Integrating geomorphic classification into broader seabed mapping workflows using the described GIS tool.

Strengths

• Implements a standardized, two-part classification framework developed by an international working group.
• Assigns five levels of classification attributes and 16 additional descriptive attributes to seabed features.
• Tool logic updates lower-level classification options based on user choices at higher levels.

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 data_gov_au.
