6/12/2014DigitalGlobe Proprietary26 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.
