ARTIST RENDERING OF WORLDVIEW-2
WorldView-2
QUALITY IMAGERY AT YOUR DISPOSAL
WorldView-2 was launched in October 2009, and was the first high-resolution 8 band multispectral commercial satellite. WorldView-2 has been European Space Imaging’s most valuable tool for years, reliably collecting very high resolution images to solve our customer’s problems. Capable of collecting up to 1 million square kilometers of imagery every day, it greatly enhances our capacity for rapid collection.
