WorldView-2 High-Resolution Satellite Imagery
WorldView-2, the world’s newest high-resolution commercial color imaging satellite, was launched on October 8, 2009 from Vandenburg Air Force Base in California. WorldView-2 is the first high-resolution satellite with 8-Multispectral imaging bands. WorldView-2 will simultaneously collect Panchromatic imagery at 0.46m and Multispectral imagery at 1.84m. Due to U.S. Government Licensing, the imagery will be made available commercially as 0.5m imagery. WorldView-2 is capable of collecting up to 975,000 square kilometers of imagery per day (376,000 square miles). Contact LAND INFO for a detailed price quote.

WorldView-2 – New High Resolution Spectral Bands
Coastal Band (400-450nm):
This band supports vegetation identification and analysis, and supports bathymetric studies based upon its chlorophyll and water penetration characteristics. Also, this band is subject to atmospheric scattering and will be used to investigate atmospheric correction techniques
Yellow Band (585-625nm):
Used to identify "yellow-ness" characteristics of targets, important for vegetation applications. Also, this band assists in the development of "true-color" hue correction for human vision representation.
Red Edge Band (705-745nm):
Aids in the analysis of vegetative condition. Directly related to plant health revealed through chlorophyll production.
Near Infrared Band (860-1040nm):
This band overlaps the NIR 1 band but is less affected by atmospheric influence. It supports vegetation analysis and biomass studies.
