Overview & HistoryWorldView-1 SpecificationsPricing

WorkdView-1 is the industry leader when it comes to high resolution coverage. This satellite collects more than 1,000,000 square kilometers (sq km) of imagery every day! After a six year break in the launch of high resolution satellites, WorldView-1 was launched by DigitalGlobe on September 18, 2007 from Vandenberg Air Force Base, CA.

As the first of the second-generation high-resolution satellites, WorldView-1 features 50-centimeter (cm) panchromatic imagery. Orbiting our planet at 496 km, it is an extremely agile satellite with an enormous archive of high resolution imagery, including stereo data for topographic model creation.
