Title: Palmyra Atoll Quickbird II Seafloor Mosaic (1.8m)
Short Name: Palmyra_Seafloor_Mosaic
Status: Completed
Publication Date: 2010
Abstract:

Benthic habitat maps of the nearshore marine environment of Pamyra Atoll 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 Nature Conservancy (TNC) and Analytical Laboratories of Hawaii (ALH), was to provide spatially-explicit information on the habitat types, biological cover and live coral cover of Palmyra Atoll's coral reef ecosystem. 0.61m panchromatic and 2.44m multi-spectral data from the QuickBird 2 satellite sensor were purchased for the mapping area. Photo-interpreters accurately and reliably delineated boundaries of features from this QuickBird 2 imagery as they appeared on the computer monitor using a software interface.

Purpose:

This product served as source information for a fine-scale assessment of the status, abundance, and distribution of marine habitats of Palmyra Atoll. The NOAA effort provides The Nature Conservancy 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, and improved assessment of human-use impacts.

Process Steps

Process Step 1

CC ID: 600585
Description:

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 QuickBird 2 imagery to increase the spatial resolution of the 2.44 m multispectral data to the panchromatic data resolution of 0.61 m.

Process Date/Time: 2010-01-01 00:00:00

Process Step 2

CC ID: 600586
Description:

Bands 1 - 7: Geo-referencing of the imagery was performed using PCI OrthoEngine module. The pansharpened PIX (PCI Geomatica native format) files were orthorectified using stereo ground control point positioning along with the Rational Functions model extracted from the original NITF files.

Process Date/Time: 2010-01-01 00:00:00

Process Step 3

CC ID: 600587
Description:

Bands 5 - 7: The method for removal of sun glint described in Hedley et al. (2005) was applied to the pansharpened, orthorectified QuickBird 2 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. This is accomplished in this methodology by applying the ratio of reflectance of the near-infrared and visible band to each cell in the scene.
