Hawaiian Islands Reef Bathymetry and Rugosity from Airborne Spectroscopy

Global Airborne Observatory bathymetry maps show high-resolution benthic depth for the Main Hawaiian Islands, derived from airborne imaging spectroscopy data collected in January 2019 and January 2020. The dataset includes multiple map products, with three separate files for each island and Hawaii Island split into quarters for manageability. These maps were created to support analysis of coral habitat complexity and reef structure.

Use Cases

• [Modeling coral reef habitat complexity] based on [high-resolution bathymetry and rugosity data]
• [Assessing drivers of reef structure] based on [island-scale bathymetric maps]
• [Coastal management and planning] based on [detailed benthic depth information for the Main Hawaiian Islands]
• [Validating satellite-derived bathymetry] based on [airborne imaging spectroscopy data]

Strengths

• Data is derived from high-resolution airborne imaging spectroscopy, a detailed remote sensing method.
• Covers all eight Main Hawaiian Islands (Maui, Kahoolawe, Lanai, Molokai, Oahu, Kauai, Niihau, and Hawaii Island).
• Associated with two peer-reviewed publications in Remote Sensing and Frontiers in Marine Science, providing methodological and analytical context.

Limitations

• Key metadata such as row count, file size, specific column names, and exact last update date are unknown across all sources.
• The dataset's structure and specific file formats are not described in the provided inputs.
• Spatial resolution and accuracy metrics for the bathymetry maps are not explicitly stated.
