Great Barrier Reef Surficial Facies Maps Using Entropy-Ratio Classification

Entropy-ratio maps for classifying surficial facies of coral reefs at any chosen resolution. The data, provided by the Australian Ocean Data Network, uses a ternary classification based on detritus, framework encrustation, and pavement, and is sensitive to zonation across reef flats. The dataset was last updated on 2026-04-16.

Use Cases

• Map coral reef facies distribution based on the ternary classification of detritus, framework, and pavement.
• Analyze reef flat zonation patterns based on the described sensitivity to all reef environments.
• Superimpose the entropy-ratio classification on other reef mapping systems as mentioned in the description.

Strengths

• Classification is described as sensitive to all reef environments, particularly zonation across reef flats.
• Method allows mapping at any chosen resolution, as stated in the description.
• Data is hosted by the authoritative Australian Ocean Data Network.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count and file size are unknown, which may limit suitability assessment.
• Data is available only in HTML and PDF formats, which may require extraction for analysis.
