NOAA and partner organizations collected hyperspectral imagery for coral reef mapping on Oahu. The AURORA system captured 72 spectral bands in the visible and near-infrared range at a 3-meter pixel resolution. Data was processed in 2000 to optimize feature detection in shallow and deep water.
Use Cases
- Classify benthic habitat types using 72 spectral bands from the AURORA hyperspectral system.
- Compare coral reef community structure over time using time-series analysis enabled by the spectral data.
- Delineate boundaries of underwater features via photointerpretation of the 3-meter resolution georeferenced imagery.
- Assess coral health by analyzing specific spectral band widths optimized for feature detection in water.
Strengths
- 72 spectral bands in the visible and near-infrared range provide detailed spectral signatures.
- 3-meter pixel resolution offers high spatial detail for feature delineation.
- Data was processed to select optimal band widths for feature detection in both shallow and deep water.
Limitations
- Data is from a single collection date in 2000, offering no temporal recency for current analysis.
- Specific row count, file size, and geographic coverage beyond Oahu are unknown.
- Class distribution and potential label noise from photointerpretation are unspecified.
