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. 2000 ground condition Complete None Planned -155.8633 -155.8188 20.0557 20.0115 CoRIS Discovery Thesaurus Map Images > IKONOS CoRIS Theme 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 None coral seagrass SAV reef IKONOS IKONOS imagery benthic habitat mangrove oceans ISO 19115 Topic Category imageryBaseMapsEarthCover 010 CoRIS Place Thesaurus 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) None U.S. Exclusive Economic Zone United States Hawaii Kona CoRIS Region MHI None None 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 mailing and physical address

Silver Spring MD 20910 301-713-3028 301-713-4388 steve.rohmann@noaa.gov 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 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 imagery was purchased in National Imagery Transmission Format (NTIF) with the associated Rational Polynomial Coefficients (RPCs). 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. Space Imaging Inc. 2000 remote-sensing image Thornton, CO Space Imaging Inc. This imagery was obtained at a 4 m pixel resolution. IKONOS Imagery 2000 ground condition multispectral imagery Used to identify and digitize benthic habitats for the eight main Hawaiian Islands. 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 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 mailing and physical address
