ISGM vocabularies

Part 1 and 2 glossaries are also available as four linked vocabularies in Simple Knowledge Organization System format (SKOS). SKOS is machine-readable and delivers definitions and hierarchies for glossary terms and concepts that can be persistently identified and ingested into content management systems:

• Vocabulary 1. Seabed geomorphology – Method Terms. General terms that are used to support implementation of the method.
• Vocabulary 2. Seabed geomorphology – Physiography. Physiographic terms derived from Harris et al (2014), used to classify the macroscale shape and geology of the global seabed.
• Vocabulary 3. Seabed geomorphology – Part 1 Morphology. Terms that are used to describe the shape of the seabed (Morphology Features).
• Vocabulary 4. Seabed geomorphology – Part 2 Geomorphology. Used to classify Part 1 Morphology Features with their process interpretation (geomorphic units).

GIS toolboxes to support implementation of the ISGM approach

• Geoscience Australia’s Semi-automated Morphological Mapping Tools (GA-SaMMT)
  GA-SaMMT is a collection of seven ArcGIS Pro Python toolboxes that use Python 3+ to map ten bathymetric high and eight bathymetric low Part 1 Morphology Features.

• Confined Morphologies Mapping Toolbox (CoMMa)
  Confined Morphologies Mapping (CoMMa) Toolbox is an ArcGIS Pro toolbox for semi-automated morphological mapping (Part 1). CoMMa includes a suite of tools for delineating and describing any type of enclosed features on a DEM, either negative or positive. CoMMa was developed by the Marine Geoscience Group (University College Cork) in collaboration with the British Geological Survey and University of Glasgow.
