With unsurpassed accuracy, agility and collection capacity, half-meter panchromatic WorldView-2 is delivering comprehensive new solutions for the marine community. resolution and 1.8 meter multispectral resolution across 8 Remote sensing of the shallow ocean floor will now become much clearer, thanks to the addition of the spectral bands. With unprec- Coastal Blue band. Analysts will be able to discriminate features more accurately and increase the edented agility and a collection scope of remote sensing applications. And, thanks to WorldView-2’s ability to collect large volumes of capacity of 975,000 km2 per day, stereo imagery, new photogrammetric techniques for calculating ocean depth are finally possible. WorldView-2 will double the Current, accurate depth measurements will provide increased navigational security, and support DigitalGlobe collection capacity detailed mapping and modeling applications. and provide worldwide intra-day revisit capabilities.
