  26. WorldView2 4 New Bands Coastal • chlorophyll absorption, blue light scattering, water depth, “true-color”; will support coastline water depth studies based upon its chlorophyll and water penetration characteristics. Also, this band is subject to atmospheric scattering and will be investigated to examine atmospheric correction techniques. Yellow • will be used to identify "yellow-ness" characteristics of targets, important for vegetation and turbidity applications. Also, this band will assist in the development of "true-color" hue correction for human vision representation. Red Edge • aids in the analysis of vegetation and vegetative condition. Directly related to plant health revealed through chlorophyll production. NIR2 • overlaps the NIR1 band may help with atmospheric correction, supports vegetation analysis and biomass studies. DigitalGlobe Proprietary

  27. Coastal Mapping • Accuracy • 30 meter depth • 1-5 meter geolocation • 2-5 meter post spacing • Spatial Resolution • 2 meter GSD • Geographic Coverage • Tropical and sub-tropical regions • Clear lakes • Clear, calm waters DigitalGlobe Proprietary

  28. Red Edge Yellow Band Pocomoke, MD RGB = NIR1,Red Edge, Red Land Use/Land Cover Identification Additional spectral bands available with WorldView-2 provide additional separability (improved accuracy) in the characteristics and identification of Land Use and Land Cover features. See following slide… DigitalGlobe Proprietary

  29. Improved Classification Accuracies QB Overall Accuracy 47.3% WV2 Overall Accuracy 76.5% Spectral Classification comparison applying the same generic signature library to both QB2 and WV2, with no corrections applied, using the same classification method. DigitalGlobe Proprietary
