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 1.84 meter* multispectral resolution. WorldView-2 has an average revisit time of 1.1 days and is capable of collecting up to 975 000 square kilometers (376 000 squre miles) per day**.

The WorldView-2 system, offering incredible accuracy, agility, capacity and spectral diversity.

Benefit

Provides highly detailed imagery for precise map creation , change detection and in-depth image analysis
Provides the ability to perform precise change detection, mapping and analysis at unprecedented resolutions in 8-band multispectral imagery

Allow creation of accurate maps in mremote areas, maximizing the utility of whatever resources are available:
- Geolocation accuracy specific specification of 6.5m CE90 at nadir, with actual accuracy in the range of 4.6 - 10.7m CE90, excluding terrain and off-nadir effects
- With registration to GCPs in image: 2.0 meters (6.6 feet) CE90

Frequent revisits increase image collection oppoetunities, enhance change detection application and enable accurate map updates
