Service Description: Benthic habitats were visually interpreted from Digital Globe's Quickbird II (QB2) commercial satellite imagery collected between 2004 and 2006. The satellite collects a four-channel multispectral image (blue, green, red, and near infra-red colors) at 2.44 m spatial resolution as well as a panchromatic image (black and white) at 0.61 m resolution. NOAA fused these images to create "pansharpened" scenes for mapping that have the high spatial resolution of the panchromatic image and the colors of the multispectral image. Three partially overlapping scenes covered the atoll. Where overlapping imagery occurred, the most recent scene with clear views of the seafloor was used. Satellite data was orthorectified by NOAA to improve its positional accuracy. Survey-grade GPS measurements were taken at 21 features around the atoll that were visible in the satellite images. Using the field positions, in addition to satellite orientation data provided by Digital Globe, each satellite scene was positioned to +/- 1.6 m (CEP 95) of its true position.

Title: Majuro Imagery
Author: Matt Kendall
Comments: Benthic habitats were visually interpreted from Digital Globe's Quickbird II (QB2) commercial satellite imagery collected between 2004 and 2006. The satellite collects a four-channel multispectral image (blue, green, red, and near infra-red colors) at 2.44 m spatial resolution as well as a panchromatic image (black and white) at 0.61 m resolution. NOAA fused these images to create "pansharpened" scenes for mapping that have the high spatial resolution of the panchromatic image and the colors of the multispectral image. Three partially overlapping scenes covered the atoll. Where overlapping imagery occurred, the most recent scene with clear views of the seafloor was used. Satellite data was orthorectified by NOAA to improve its positional accuracy. Survey-grade GPS measurements were taken at 21 features around the atoll that were visible in the satellite images. Using the field positions, in addition to satellite orientation data provided by Digital Globe, each satellite scene was positioned to +/- 1.6 m (CEP 95) of its true position.
