Estimated Depth Maps of the Northwestern Hawaiian Islands Derived from High Resolution IKONOS Satellite Imagery (Draft)

Published by NOAA's Ocean Service, National Centers for Coastal Ocean Science (NCCOS) | National Oceanic and Atmospheric Administration, Department of Commerce | Metadata Last Checked: January 31, 2026 | Last Modified: 2002-12-31T00:00:00.000+00:00
Estimated shallow-water, depth maps were produced using rule-based, semi-automated image analysis of high-resolution satellite imagery for nine locations in the Northwestern Hawaiian Islands. This project is a cooperative effort between the National Oceanic and Atmospheric Administration, State of Hawaii Department of Land and Natural Resources, and the U.S. Fish and Wildlife Service to produce benthic habitat maps and georeferenced imagery for the Northwestern Hawaiian Islands. This project was conducted in support of the U.S. Coral Reef Task Force.
