The NGA has initiated a program to evaluate high resolution commercial sensors developed by Space Imaging, DigitalGlobe, Orbimage and others. Recent evaluations have involved QuickBird panchromatic products including the Basic 1B, Ortho-Ready Standard 2A, orthorectified, and Basic Stereo Pair products. This paper presents the results of an additional geo-positional accuracy evaluation of multispectral QuickBird Ortho-Ready Standard 2A images. These products were compared to a globally distributed set of Ground Control Points (GCPs), and the calculated geo-positional accuracy was compared to the published QuickBird specifications and to the panchromatic Ortho-Ready Standard 2A product. The results of the panchromatic and multispectral bands are compared, and the band-to-band registration of the multispectral arrays is evaluated.
