A 2026 standardized framework for marine and coastal geomorphic mapping developed by the International Seabed Geomorphology Mapping Working Group. It includes a hierarchical glossary of over 400 terms across 11 classes and a system for classifying 40 bathymetric shapes. The framework is supported by open-access, machine-readable digital vocabularies and GIS tools.
Use Cases
- Standardizing seabed geomorphic terminology across global datasets based on the hierarchical framework.
- Mapping bathymetric morphology features based on the 40 standardized shape classifications.
- Tailoring geomorphic classification to specific data quality and application needs using the BGU hierarchy.
- Integrating geomorphic interpretations from different disciplines using the common glossary.
Strengths
- Framework includes a glossary of over 400 standardized geomorphic terms.
- Classification system defines 40 bathymetric morphology features.
- Supports hierarchical classification from Setting/Process down to sub-types.
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 or source bias inherent to data_gov_au.
