Kure Atoll, Midway Atoll, Pearl and Hermes Atoll, Lisianski Island, Laysan Island, French Frigate Shoals, and Nihoa Island are positioned to within five (5) meters at sea level. Necker Island is positioned to within 15 meters at sea level. Maro Reef is positioned to within eight (8) meters at sea level. Vertical Positional Accuracy Report none reported High-resolution satellite imagery was analyzed to produce estimated depth maps of the North Western Hawaiian Islands. Estimated depth can be determined from imagery for clear water to between 20 m and 35 m, depending on the bottom type and absolute water clarity. Because the water surrounding Gardner Pinnacles is too deep, no estimated depth was generated there. No satellite imagery was available for Gambia Shoal. Multispectral satellite imagery was positioned using National Geodetic Survey ground control data for Kure Atoll, Midway Atoll, Pearl and Hermes Atoll, Lisianski Island, Laysan Island, French Frigate Shoals, and Nihoa Island. Satellite imagery of Necker Island was positioned using satellite ephemeris data. Satellite imagery of Maro Reef was positioned using a combination of satellite ephemeris data and supplemental depth transect data. Estimated depth was produced using a band-ratio procedure (see Stumpf et al., Limnology and Oceanography, 2003). The procedure uses two multispectral bands and requires very little tuning. Using this method, estimated depth can be determined in clear water to between 20- 35 meters, depending on the bottom type and water clarity. Estimated depth (estimated water depths in feet) were assigned either a range of numeric values or a single numeric value representative of (but not equal to) depth. These individual numeric values or ranges of numeric values were used to apply a ramped RGB color palette. Because the environment in the NWHI is very complex, two profiles of estimated depth were generated. The "shallow-water" RGB depth profile was applied to Kure Atoll, Midway Atoll, Pearl and Hermes Atoll, and French Frigate Shoals. The "deep-water" RGB depth profile was applied to Lisianski Island, Laysan Island, Maro Reef, Necker Island, and Nihoa Island. Because the water surrounding Gardner Pinnacles is too deep, no estimated depth was generated there. 2001-01-01T00:00:00 National Oceanic and Atmospheric Administration (NOAA), National Ocean Service (NOS), National Centers for Coastal Ocean Science (NCCOS), Center for Coastal Monitoring and Assessment (CCMA), Remote Sensing Team Remote Sensing Specialist 301-713-3028 301-713-4384 1305 East West Highway, N/SP Silver Spring Maryland 20910 Richard.Stumpf@noaa.gov Monday to Friday, 0800 -1700, EST processor Source Contribution: High resolution satellite imagery was analyzed to produce estimated depth maps of the Northwestern Hawaiian Island Source Type: IKONOS high-resolution satellite imagery IKONOS Panchromatic and Multispectral Imagery for the Northwestern Hawaiian Islands 2002-01-01 publication 1 Space Imaging Thornton CO publisher Space Imaging originator Acquisition_Date: Gardner Pinnacles (2 swaths; 20001014) Acquisition_Date: Kure Atoll (2 swaths; first acquisition; 20001120) Acquisition_Date: Kure Atoll (2 swaths; second acquisition; 20010926) Acquisition_Date: Laysan Island (swaths 1 and 3; 20010124) Acquisition_Date: Laysan Island (swath 2; 20010215) Acquisition_Date: French Frigate Shoals (first acquisition; 4 swaths; 20001011) Acquisition_Date: French Frigate Shoals (second acquisition; swaths 1, 2, and 3; 20010911) Acquisition_Date: French Frigate Shoals (second acquisition; swath 4; 20010919) Acquisition_Date: Midway Atoll (swath 1; 20010122) Acquisition_Date: Midway Atoll (swath 2; 20010318) Acquisition_Date: Lisianski Island (3 swaths; 20001012) Acquisition_Date: Nihoa (swath 1; 20010109) Acquisition_Date: Nihoa (swath 2; 20010120) Acquisition_Date: Nihoa (swath 3; 20010418) Acquisition_Date: Pearl and Hermes Atoll (3 swaths; 20010119) Acquisition_Date: Maro Reef (3 swaths; 20010724) Acquisition_Date: Necker Island (2 swaths; 20010126) 2000-01-01 2001-01-01 annually This metadata was automatically generated from the FGDC Content Standard for Digital Geospatial Metadata standard (version FGDC-STD-001-1998) using the 2016-01-11 version of the FGDC RSE to ISO 19115-2 transform.
