WorldView-1 offers panchromatic imagery at 50cm resolution,

With unprecedented accuracy giving map ready imagery – 1:12,000 US scale or better – right off the satellite, while exceptional agility means acquistion of multiple targets on each pass and faster collection, up to 750,000 km2/day. Combined with QuickBird and WorldView-2 (to be launched in 2009) it will be part of a constellation offering very high revisit and large area collection capacity

Operating at an altitude of 496 kilometers, WorldView-1 has an average revisit time of 1.7 days. The satellite is also equipped with state-of-the-art geolocation accuracy capabilities and exhibits stunning agility with rapid targeting and efficient in-track stereo collection.
