The WorldView-2 Advantage

Improved Spectral Analysis

With 8 multispectral bands and a huge archive, WorldView-2 is the satellite of choice for those completing spectral analysis. The additional bands improve every analytic technique including classifications, vegetative analysis and change detection.

Extreme Agility

WorldView-2 is an extremely agile satellite that can collect large areas of high-resolution mono imagery, as well as stereo data from which accurate topographic models can be created.

High Positional Accuracy

Featuring positionally accurate 8-band imagery, WorldView-2 is appropriate for mapping projects and site monitoring; and is the choice for spectral analysis.

Overview & History

WorldView-2 was the most technologically-advanced high-resolution satellite ever launched before it’s twin, WorldView-3, reached orbit. The Maxar Technologies satellite was launched into space on October 8, 2009 from Vandenberg Air Force Base, CA. WorldView-2 collects 46-centimeter (cm) panchromatic and 1.85-meter (m) multispectral imagery.

WorldView-2 features the first 8-band multispectral imaging system, adding a coastal, yellow, red edge and an additional near-infrared red (NIR) band to the traditional four (i.e. blue, green, red and NIR). Positioned 770 kilometers (km) above the planet, WorldView-2 collects up to 785,000 sq km of 8-band imagery every day. No wonder it’s our best seller!
