GA-SaMMT: ArcGIS Tools for Seabed Morphology Mapping

Geoscience Australia's Semi-automated Morphological Mapping Tools (GA-SaMMT) are a suite of seven ArcGIS Pro Python toolboxes for mapping and classifying seabed features. The tools map ten bathymetric high and eight bathymetric low morphology features, as defined in Dove et al., 2020. They include tools for feature detection, attribute calculation, and classification.

Use Cases

• Mapping bathymetric high features using TPI, LMI, or Openness algorithms.
• Calculating shape, topographic, and profile attributes for identified seabed features.
• Classifying detected bathymetric features into standardized morphological categories.
• Processing seabed data with multiprocessing-enabled tools for faster attribute calculation.

Strengths

• The tool suite comprises seven specialized toolboxes with 22 distinct tools for a complete workflow.
• It implements a published morphological classification scheme for ten high and eight low feature types.
• Includes a fast version of attribute calculation tools with multiprocessing capabilities.

Limitations

• Key metadata such as license, author, and exact file size is missing from all platform entries.
• The dataset's description is repeated verbatim across multiple listings, suggesting limited contextual information.
• The 'Last updated' date shows a conflict, with one source listing 2026-05-05 and others listing 2026-06-04.
