Entropy-ratio maps enable classification of coral reef surface facies at a user-defined resolution. The method uses a ternary classification based on detritus, framework encrustation, and pavement, subdivided by their degree of mixing. This dataset, hosted by the Australian Ocean Data Network, provides an example application for the Great Barrier Reef.
Use Cases
- Map surficial reef facies distribution based on the described ternary classification system.
- Analyze zonation patterns across reef flats based on the method's described sensitivity.
- Superimpose entropy-ratio classifications on other reef mapping schemes based on the description.
- Test resolution-dependent mapping of coral reef environments based on the method's capability.
Strengths
- Method is sensitive to all reef environments, particularly zonation across reef flats.
- Classification can be superimposed on other mapping schemes, increasing flexibility.
- Platform indicates the dataset originates from the authoritative Australian Ocean Data Network.
Limitations
- Column-level documentation is absent; field semantics must be inferred after download.
- Row count and dataset scale are unknown, which may limit suitability assessment.
- Data files are in PDF and HTML formats, which may require extraction for analysis.
