Title:
2000 IKONOS Image of St. John Utilized to derive Benthic Habitat Maps (IK_304713_0000000.img)
Abstract:
Benthic habitat maps of the nearshore marine environment of St. John, U.S. Virgin Islands were created by visual interpretation of remotely sensed imagery. The objective of this effort, conducted by NOAA's Center for Coastal Monitoring and Assessment - Biogeography Branch in partnership with the U.S. National Park Service (NPS), was to provide spatially-explicit information on the habitat types, biological cover and live coral cover of St. John's coral reef ecosystem. One-meter panchromatic and four-meter multi-spectral data from the IKONOS satellite sensor were purchased for the mapping area. Photo-interpreters accurately and reliably delineated boundaries of features from this IKONOS imagery as they appeared on the computer monitor using a software interface.

Why was the data set created?

This product served as source information for a fine-scale assessment of the status, abundance, and distribution of marine habitats of St. John. The NOAA effort provides the U.S. National Park Service with increased technical capacity for ocean exploration, management, and stewardship. Direct implications to management measures include evaluation of management efficacy, a spatial framework for improved monitoring sampling design, improved assessment of human-use impacts, and marine spatial planning to support alternative marine protected area boundary alternatives.

    Date: 2008 (process 1 of 4)
    Bands 1 - 7: Geo-referencing of the imagery was performed using PCI OrthoEngine module. The NITF IKONOS imagery were orthorectified using the Rational Functions extracted from the NITF, then further supplemented with stereo ground control point positioning using a robust polynomial math model through bundle adjustment of all the satellite scenes.

    IKONOS Imagery was obtained from Space Imaging LLC, 12076 Grant Street, Thornton, Colorado 80241 <http://www.spaceimaging.com>

    Bands 1 - 7: PCI OrthoEngine Pansharpening module was employed to create a high-resolution color image to be used for visual interpretation by NOAA scientists. It was applied to the IKONOS imagery to increase the spatial resolution of the 4 m multispectral data to the panchromatic data resolution of 1 m.

    Bands 5 - 7: The method for removal of sun glint described in Hedley et al. (2005) was applied to the IKONOS imagery to remove specular reflection from the sea surface. Reflection of solar radiation on non-flat water surfaces often results in areas of bright white sun glint in remotely sensed imagery. Typically, sun glint forms bands of white along wave edges on the windward side of nearshore environments. Sun glint can obscure bottom features and should be removed before habitat delineation.
