WorldView-2 is an imaging and environment-monitoring satellite from Maxar of the United States which launched on 8 October 2009 and remains operational.
It is the follow-on spacecraft to WorldView-1.
|Orbit Altitude||770 km|
|Orbit Period||100 minutes|
|Revisit Time||Up to 1.1 days|
|Equator Crossing Time||10:30 am descending node|
The overall objective is to meet the growing commercial demand for high-resolution satellite imagery. WorldView-2 provides commercially available panchromatic imagery of 0.46 m resolution, and eight-band multispectral imagery with 1.84 m resolution - representing one of the highest available spaceborne resolutions on the market.
WorldView-110 camera (WV110)
This instrument collects images at 0.41 metre panchromatic and 1.64 metre 8-band multi-spectral data. Along with the Pan (450-800 nm) and the four typical multispectral bands (blue, green, red, NIR), WorldView-2 has four additional bands for enhanced multispectral analysis (coastal blue, yellow, red edge, NIR2) designed to improve segmentation and classification of land and aquatic features.

These collections are available as part of the Maxar Standard Satellite Imagery products and are distributed by European Space Imaging (EUSI).
ESA will support as many high-quality and innovative projects as possible within the quota limit available, therefore only a limited amount of products can be made available to each project.
The following collections are available:
