Coastal to Deep-Marine Geomorphic Classification Framework and Glossary

A global marine and coastal geomorphic classification framework developed by the International Seabed Geomorphology Mapping Working Group. It includes a standardized glossary of over 400 terms across 11 overlapping classes and a two-part mapping approach separating morphology from interpretation. The framework is designed to support consistent terminology from global to local scales.

Use Cases

• Classify seabed morphology based on 40 standardized bathymetric shape terms.
• Assign hierarchical geomorphic interpretation using a glossary of over 400 terms.
• Tailor marine habitat mapping classification to available data quality and application needs.
• Support evidence-based decision-making for ocean management using a standardized framework.

Strengths

• Framework includes a glossary of over 400 standardized geomorphic terms.
• Classification process separates morphological mapping from geomorphic interpretation to constrain uncertainty.
• Implementation is supported by open-access, machine-readable digital vocabularies and GIS tools.

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.
