Four linked vocabularies developed by the International Seabed Geomorphology Mapping Working Group (ISGM-WG) to support standardized global seabed mapping. The vocabularies cover method terms, physiography, morphology features, and geomorphic units, and were published by Geoscience Australia. The underlying classification scheme was published in two parts, with the morphology glossary in 2020 and the geomorphology framework in 2023.
Use Cases
- Standardizing seabed map annotations based on the provided morphology and geomorphology vocabularies.
- Classifying seabed features with process interpretations based on the structured geomorphic unit terms.
- Integrating macroscale seabed shape and geology data using the retained physiographic terms.
- Developing or validating automated seabed feature classification systems using the consistent framework design.
Strengths
- Developed by an international working group (ISGM-WG) for standardized global use.
- Includes four distinct, linked vocabularies covering methods, physiography, morphology, and geomorphic units.
- Based on a published two-part classification scheme with peer-reviewed references (Dove et al., 2020; Nanson et al., 2023).
Limitations
- Column-level documentation is absent; field semantics must be inferred after download.
- Row count is unknown, which may limit suitability assessment.
- Data format is HTML, which may require parsing to extract structured vocabulary data.
