Coral Sea Sentinel 2 Marine Satellite Composite Imagery, 2015-2021

Composite satellite images for the Coral Sea region based on 10 m resolution Sentinel 2 imagery from 2015 to 2021. This draft version from the Australian Ocean Data Network was prepared from approximately 60% of the available imagery and contains 31 tiles with 5 different enhancement styles each. The collection is intended to allow mapping of reef and island features.

Use Cases

• Mapping coral reef tops and shallow features based on the contrast-enhanced 'ReefTop' and 'Shallow' imagery styles.
• Analyzing deeper marine bathymetry to 50-60 meters using the 'DeepFalse' ultraviolet band composite.
• Identifying vegetation on cays and beach rock using the standard 'TrueColour' imagery.
• Cross-validating mapped features by comparing the 'R1' and 'R2' composite versions for each tile.

Strengths

• Provides 10-meter resolution satellite imagery for 31 tiles in the Coral Sea.
• Includes 5 distinct color and contrast enhancement styles per tile, each designed to highlight specific marine or terrestrial features.
• Covers a multi-year time range from 2015 to 2021.

Limitations

• This is a draft version prepared from approximately 60% of the available Sentinel 2 imagery; an improved version has been released.
• Description metadata is limited; actual data quality requires manual inspection after download.
• The 'DeepFalse' enhancement technique does not work in areas where water is not clear, as ultraviolet light scatters easily.
