38661 207b-0613-272217 Data Set Published / External 37187 Hawaii_images_2000 Project Completed 2000 This project is a cooperative effort among the National Ocean Service, National Centers for Coastal Ocean Science, Center for Coastal Monitoring and Assessment; the University of Hawaii; and Analytical Laboratories of Hawaii, LLC. The goal of the work was to develop coral reef mapping methods and compare benthic habitat maps generated by photointerpreting georeferenced color aerial photography, hyperspectral and IKONOS satellite imagery. The enhanced spectral resolution of hyperspectral and control of bandwidths of multispectral data yield an advantage over color aerial photography particularly when coral health and time series analysis of coral reef community structure are of interest. Depending on the type of instrument, a spectral imaging system can be utilized to see multiple colors from ultraviolet through the far infrared range. The AURORA hyperspectral imaging system collected 72 ten nm bands in the visible and near infrared spectral range with a 3 meter pixel resolution. The data was processed to select band widths, which optimized feature detection in shallow and deep water. Photointerpreters can accurately and reliably delineate boundaries of features in the imagery as they appear on the computer monitor using a software interface such as the Habitat Digitizer. The National Ocean Service is conducting research to digitally map biotic resources and coordinate a long-term monitoring program that can detect and predict change in U.S. coral reefs, and their associated habitats and biological communities. 485 Theme ISO 19115 Topic Category environment Theme ISO 19115 Topic Category imageryBaseMapsEarthCover Theme NOS Data Explorer Topic Category Environmental Monitoring Theme NOS Data Explorer Topic Category Remotely Sensed Imagery/Photos Theme AURORA hyperspectral imagery Theme SAV Theme benthic Theme coral Theme habitat Theme mangrove Theme oceans Theme reef Theme seagrass Spatial Hawaii Spatial Oahu Spatial U.S. Exclusive Economic Zone Spatial United States National Centers for Coastal Ocean Science Silver Spring MD Data Set None Planned remote sensing image The National Oceanic and Atmospheric Administration (NOAA) National Centers for Coastal Ocean Science(NCCOS) produced this data CD-ROM.

File naming convention is as follows 'flightline number-date(s) acquired-hyperspectral or airphoto imagery'. Hyperspectral flightline files will end in either 272217 or 332211 representing the band number in the respective file. Band numbers equate to the following spectral wavelength in nanometers: 27 - 605.51991, 22 - 556.918030, 17 - 508.319000, 33 - 663.835022, and 11 - 450.001007. These approximate true-color band combinations were chosen to highlight shallow (272217) and deep (332211) water benthic features. Note that the resolution of the georeferenced imagery has been degraded significantly to reduce file size and facilitate internet viewing.; None None https://coastalscience.noaa.gov/datasets/ccma/biogeo/hawaii/mosaics/207b-0613-HSI.zip Downloadable Data MrSID SID-MrSID/Multiresolution Seamless Image DB https://ccma.nos.noaa.gov/products/biogeography/hawaii_cd/data/ Online Resource https://ccma.nos.noaa.gov/products/biogeography/hawaii_cd/data/oahufl.aspx Online Resource https://coastalscience.noaa.gov/datasets/ccma/biogeo/hawaii/mosaics/207b-0613-HSI.zip Online Resource 2013-12-23 Date that the source FGDC record was last modified. 2017-04-05 Converted from FGDC Content Standards for Digital Geospatial Metadata (version FGDC-STD-001-1998) using 'fgdc_to_inport_xml.pl' script.

Microsoft Windows 2000 Version 5.0(Build 2195) Service Pack 3; ESRI ArcCatalog 8.2.0.700 The hyperspectral imagery were obtained at a 3 meter pixel resolution Habitat delineations could be made accurately in water depths up to 30 meters. Band combinations were selected which optimized benthic habitat information in shallow and deep water and the scenes were converted into RGB composites. The shallow band IDs and centers were configured as: 1) Band 17 at 508.319 nm 2) Band 22 at 547.918 nm 3) Band 27 at 605.516 nm The deep band IDs and centers were configured as: 1) Band 11 at 450.001 nm 2) Band 22 at 547.918 nm 3) Band 33 at 663.835 nm All habitat delineations were completed by a photointerpreter on data that had been processed only to maximize specific band widths for viewing data at varying depths. 1 The hyperspectral image data were collected using the AURORA Hyperspectral Imaging data acquisition system (Advanced Power Technologies, Inc). Navigation data were incorporated using the Applanix inertial navigation system. The imaging system was used to collect 72 ten nm bands in the visible and near infrared spectral range at a three meter pixel resolution.
