WorldView-2

Provides highly detailed imagery for precise map creation, change detection and in-depth image analysis (note that imagery must be re-sampled to 50-cm for non-US Government customers)

Provides the ability to perform precise change detection and mapping at unprecedented resolutions in multispectral imagery, and opens door to creation of numerous new products

Allows the creation of accurate maps in remote areas, maximizing the utility of whatever resources are available:

• Geolocation Accuracy specification of 6.5m CE90, with predicted performance in the range of 4.6 to 10.7 meters (15 to 35 feet) CE90, excluding terrain and off-nadir effects
• With registration to GCPs in image: 2.0 meters (6.6 feet) CE90

Collects, stores and downlinks a greater supply of frequently updated global imagery products than competitive systems

• DigitalGlobe ImageLibrary filled with unrivaled speed
• Broadest range of collection sizes, without sacrificing capacity from small points to long strips and large areas
• Stereoscopic areas on a single pass, ensuring image continuity and consistency of quality

Expedites image processing and delivery to customers where speed is a driving factor

Extends the range of suitable imaging collection targets and enhances image interpretability

Frequent revisits increase image collection opportunities, enhance change detection applications and enable accurate map updates
