ISGM-SGC: Seabed Geomorphology Classification Tool and Framework

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

Use Cases

• Standardize seabed feature nomenclature based on the described classification framework.
• Create consistent seabed geomorphology maps for baseline information.
• Integrate classification workflows with complementary morphology mapping tools.
• Attribute mapped seabed shapes with geomorphic interpretations.

Strengths

• Tool implements a standardized, two-part classification framework developed by an international working group.
• Assigns five levels of classification attributes and 16 additional interpretation attributes.
• Developed as an Esri ArcGIS Pro Python tool using Python 3+.

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.
