GA-SaMMT: Semi-automated Morphological Mapping Tools for Seabed Characterisation

Geoscience Australia's GA-SaMMT comprises seven ArcGIS Pro Python toolboxes for seabed characterisation. The tools map ten bathymetric high and eight bathymetric low Morphology Features, as well as three classes of Morphological surfaces. The system includes tutorials, a user guide, sampled data, and examples of real-world applications.

Use Cases

• Map bathymetric high features based on TPI and Openness tools
• Classify bathymetric features into Morphological Feature categories defined in Dove et al. (2020)
• Calculate shape, topographic, and profile attributes for bathymetric features
• Map Morphological surfaces based on bathymetry and slope data
• Merge and connect features to assist mapping processes

Strengths

• Includes seven distinct toolboxes with 20+ individual tools
• Provides tutorials, user guide, sampled data, and step-by-step examples
• Has been applied to many study areas with published real-world applications

Limitations

• Column-level documentation is absent; field semantics must be inferred after download
• Row count is unknown, which may limit suitability assessment
