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 NCCOS Scientific Data Coordinator NCCOS.data@noaa.gov pointOfContact NCCOS Scientific Data Coordinator NCCOS.data@noaa.gov custodian notPlanned Environmental Monitoring Remotely Sensed Imagery/Photos theme NOS Data Explorer Topic Category IKONOS IKONOS imagery SAV benthic coral habitat mangrove oceans reef seagrass theme Hawaii Kona U.S. Exclusive Economic Zone United States place DOC/NOAA/NOS/NCCOS > National Centers for Coastal Ocean Science, National Ocean Service, NOAA, U.S. Department of Commerce dataCentre Global Change Master Directory (GCMD) Data Center Keywords 2017-04-24 publication 8.5 Earth Science Data and Information System, Earth Science Projects Division, Goddard Space Flight Center (GSFC), National Aeronautics and Space Administration (NASA) https://forum.earthdata.nasa.gov/app.php/tag/GCMD%2BKeywords GCMD Keyword Forum Page Global Change Master Directory (GCMD). 2025.

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 mosaicked to within one pixel width, and were processed to minimize atmospheric effects and compensate for water column effects. Completeness Report 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. Conceptual Consistency 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 mosaicked 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 Source Contribution: Used to identify and digitize benthic habitats for the eight main Hawaiian Islands. | Source Geospatial Form: remote-sensing image | Type of Source Media: IKONOS Imagery IKONOS Satellite Imagery 2000-01-01 publication Space Imaging Inc. http://www.geoeye.com WWW:LINK-1.0-http--link Source Citation URL Source Citation URL information 2000
