The planned launch of WorldView-2, DigitalGlobe’s second next-generation class high-resolution satellite, is expected to nearly double DigitalGlobe's collection capabilities to approximately two million square kilometers per day, enable intra-day revisits to specific geographic areas, and enhance the company's ability to collect up-to-date imagery.
The additional capacity and more frequent revisit rate are expected to provide DigitalGlobe’s customers with up-to-date and comprehensive high-resolution satellite imagery products and services.
WorldView-2 is expected to be able to collect imagery at 0.46 meter resolution. Due to NOAA operating license restrictions, all imagery will be re-sampled to 0.50 meter resolution unless the U.S. Government has granted a customer-specific waiver of the restriction.
DigitalGlobe expects images and products from WorldView-2 to be available approximately 90 days following a successful launch.
