Spectral Library for Lihou Reef Substrate from 2008 Survey

2008 spectral reflectance data for aquatic substrates at Lihou Reef, collected for habitat mapping and change detection. The dataset is part of the Australian National Spectral Database, managed by CSIRO's Wealth from Oceans research program. It was published in a 2009 report for the Department of Environment, Water, Heritage and the Arts.

Use Cases

• Classify substrate type (e.g., sand, coral, seagrass) using spectral reflectance signatures.
• Train supervised classification algorithms for habitat mapping from satellite or airborne imagery using the library's reference spectra.
• Detect changes in benthic cover over time by comparing new imagery against the 2008 spectral baselines.
• Validate the accuracy of spectral unmixing models for mixed pixels in reef environments.

Strengths

• Data is part of a national authoritative database (National Spectral Database).
• Spectral measurements are tied to a specific, documented location (Lihou Reef) and year (2008).

Limitations

• Specific sample count, spectral resolution, and number of substrate classes are unknown.
• Data is from a single year (2008), limiting analysis of temporal trends without newer reference data.
• Geographic coverage is restricted to one reef system, which may not represent other marine regions.
