The WorldView-1 Advantage

Global Coverage

The archive of WorldView-1 is filled with 10,000 sq km (or larger) rectangles of continuous high resolution imagery. It would be unusual if the WorldView-1 archive did not contain at least one image over your location.

Stereo Imagery

WorldView-1 is an extremely agile satellite that can collect stereo imagery. Stereo imagery is the raw data needed to create accurate elevation models.

High Positional Accuracy

With impressive positional accuracy (often even without orthorectification) and an ever-expanding archive, WorldView-1 is appropriate for regional and local mapping projects, site monitoring and land use determination.

Overview & History

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 Maxar Technologies 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.
