GA-SaMMT: Semi-automated Seabed Morphology Mapping Tools for ArcGIS Pro

Geoscience Australia's Semi-automated Morphological Mapping Tools (GA-SaMMT) are a suite of seven ArcGIS Pro Python toolboxes for seabed characterisation. The tools map ten bathymetric high and eight bathymetric low morphology features, plus three morphological surface classes, as defined in published research. The package includes tutorials, a user guide, sample data, and has been applied to multiple real-world study areas.

Use Cases

• Mapping bathymetric high features like ridges and banks based on TPI and Openness algorithms.
• Classifying bathymetric low features such as channels and depressions into defined morphological categories.
• Calculating shape, topographic, and profile attributes for extracted seabed features to support quantitative analysis.
• Generating morphological surface maps from bathymetry and slope data for habitat or geological studies.

Strengths

• Includes seven specialized toolboxes with a total of 20 distinct mapping and analysis tools.
• Based on a published morphological feature taxonomy defining ten high and eight low feature types.
• Provides multiprocessing capabilities in one toolbox version for improved performance on large datasets.
• Supported by tutorials, a user guide, sample data, and documented 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 for specific project scales.
• Requires ArcGIS Pro and Python 3+, creating a dependency on proprietary software for full use.
