Geoscience Australia Data produced a report detailing the iterative methodology for creating seascape classifications for Australia's marine region. The process uses an unsupervised 'crisp' ISOClass classification in ERMapper, combining biophysical properties with consistent relationships to benthic biota. An initial validation of the classification technique was performed on a subset of data for the Tasmanian shelf using an alternative 'fuzzy' classification.
Use Cases
- Validating unsupervised classification techniques for marine habitats based on the described 'fuzzy' classification method.
- Mapping benthic biota relationships using biophysical properties as described in the classification process.
- Developing regional marine planning zones based on the documented seascape creation methodology.
Strengths
- Report includes a detailed appendix documenting the different datasets used across planning zones.
- Methodology underwent initial validation on a subset of data for the Tasmanian shelf.
- Classification uses biophysical properties with definable relationships to benthic biota across Australia's entire marine region.
Limitations
- Column-level documentation is absent; field semantics must be inferred after download.
- Row count is unknown, which may limit suitability assessment.
- Data files are in PDF and HTML formats, which may require extraction for computational analysis.
