Thorton CO publisher REMOTE SENSING IMAGE This project is a cooperative effort between 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. Multispectral (blue/green/red/near-infrared) IKONOS imagery was obtained at a four meter pixel resolution. The IKONOS imagery was processed to minimize atmospheric and water column effects. 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. completed National Oceanic and Atmospheric Administration (NOAA), National Ocean Service (NOS), National Centers for Coastal Ocean Science (NCCOS), Center for Coastal Monitoring and Assessment (CCMA), Biogeography Program Biogeography Team Leader, Mapping Manager 301-713-3028 301-713-4388 1305 East West Highway Silver Spring MD 20910 steve.rohmann@noaa.gov pointOfContact notPlanned CoRIS_Metadata theme NCEI Geoportal Filter Main 8 Hawaiian Islands Benthic Habitat Mapping 1129 1026 project CRCP Project Map Images > IKONOS theme CoRIS Discovery Thesaurus EARTH SCIENCE > Biosphere > Zoology > Corals > Reef Monitoring and Assessment > Mapping > Habitat Mapping EARTH SCIENCE > Biosphere > Zoology > Corals > Reef Monitoring and Assessment > Remote Sensing > Satellite (digital scans) > IKONOS theme CoRIS Theme Thesaurus coral seagrass SAV reef IKONOS IKONOS imagery benthic habitat mangrove oceans theme None OCEAN BASIN > Pacific Ocean > Central Pacific Ocean > Hawaiian Islands > Hawaii Island > Hawaii Island (19N155W0003) COUNTRY/TERRITORY > United States of America > Hawaii > Hawaii > Hawaii Island (19N155W0003) place CoRIS Place Thesaurus U.S. Exclusive Economic Zone United States Hawaii Kona place None MHI place CoRIS Region The National Oceanic and Atmospheric Administration (NOAA), National Centers for Coastal Ocean Science (NCCOS), Biogeography Program produced this data CD-ROM.

When using image analysis software capable of reading NITF files with associated RPCs, the horizontal positioning error never exceeded 15 m (for locations where there is little or no vertical relief to affect image pixel displacement. The IKONOS imagery swaths, were mosaiced to within one pixel width, and were processed to minimize atmospheric effects and compensate for water column effects. The IKONOS imagery were optimized to maximize true color and during the map preparation the color was strategically manipulated to extract the most habitat information. The IKONOS satellite imagery were processed to remove atmospheric effects and compensate for water column effects. All of the IKONOS images were collected with collection angles of less than 20 degrees from nadir. Constraining the collection angle is important because positioning features on the seabed using satellite imagery is affected by refraction of light through the water column. When the collection angle is limited to less than 20 degrees, the maximum offset of seabed features would be less than 4 m in water less than 15 m deep and less than 8 m in water less than 30 meters deep. The IKONOS imagery was purchased in National Imagery Transmission Format (NITF) with the associated Rational Polynomial Coefficients (RPCs) in 11-km-wide swaths. NOS mosaiced the IKONOS imagery swaths to produce complete images of locales to within one pixel width. The IKONOS satellite imagery was processed to minimize atmospheric and water column effects. First, the raw satellite images were converted from Digital Numbers (DNs) to normalized reflectance. Normalized reflectance converts DNs into standardized, satellite-independent, comparable values. The acquisition angles (ephemeris data) of the satellite relative to the ground at the time of image acquisition were also used. Calibration coefficients for the satellite, provided by Space Imaging, were used to calculate at-satellite radiance, which was then transformed to reflectance. The normalized reflectance imagery was then transformed into water reflectance (or the signal less than 10 cm above the water surface). Water reflectance uses the near-infrared band to remove radiance attributable to atmospheric and surface effects. 2002-01-01T00:00:00 National Oceanic and Atmospheric Administration (NOAA), National Ocean Service (NOS), National Centers for Coastal Ocean Science (NCCOS), Center for Coastal Monitoring and Assessment (CCMA), Biogeography Program Biogeography Team Leader, Mapping Manager 301-713-3028 301-713-4388 1305 East West Highway Silver Spring MD 20910 steve.rohmann@noaa.gov processor Source Contribution: Used to identify and digitize benthic habitats for the eight main Hawaiian Islands.
