WorldView-2

WorldView-2, launched October 2009, is the first high-resolution 8-band multispectral commercial satellite. Operating at an altitude of 770 kilometers, WorldView-2 provides 46 cm* panchromatic resolution and 1.85 meter* multispectral resolution. WorldView-2 has an average revisit time of 1.1 days and is capable of collecting up to 785,000 square kilometers (303,000 square miles) of 8-band imagery per day, greatly enhancing the DigitalGlobe multispectral collection capacity for more rapid and reliable collection.
The WorldView-2 system, offering incredible accuracy, agility, capacity and spectral diversity, allows DigitalGlobe to substantially expand its imagery product offerings to both commercial and government customers.
