ARTIST RENDERING OF WORLDVIEW-1

WorldView-1

THE START OF A NEW GENERATION

 

WorldView-1 was launched September 2007, and is the first of the WorldView next-generation satellites. Equipped with revolutionary technology, WorldView-1 proved that collecting sub 1 m imagery is possible and incredibly useful for a huge range of new applications, launching a new era in the remote sensing industry.
