The First Images From the World's Most Powerful Commercial Satellite



This month, a company called DigitalGlobe launched what was billed as the world’s sharpest commercial Earth-imaging satellite. Called WorldView-3, the $500 million gadget can snap images of the ground at a 30-centimeter resolution. That’s sharp enough to see “not only a car, but the windshield and the direction the car is going,” the company boasted in a press release—as well as home plate on a baseball diamond, or the health of agricultural crops or even individual trees.

Will Oremus is Slate's senior technology writer. 

In fact, it’s so sharp that the company isn’t allowed to show the satellite’s full-resolution images to the public yet. The U.S. government recently eased its restrictions on high-resolution commercial satellite imagery, but the change won’t take full effect until February 2015. Still, the 40-centimeter versions you’ll see below rank among the sharpest yet seen by non-classified eyes.

First, here’s a gif of the WorldView-3 satellite’s Aug. 13 launch, as viewed by one of the company’s other satellites

And here is a Web-optimized version of one the first images DigitalGlobe has released since the launch. It shows the Madrid Airport in Spain along with the surrounding neighborhood:

Here's a zoomed-in view of the airport, taken from the full image above:

Ditto for some of the nearby homes:


And here's an ever closer crop on an individual swimming pool at what appears to be a little water park:

Why does high-resolution commercial satellite imagery matter? As I explained whenGoogle bought SkyBox, a rival Earth-imaging startup, its immediate applications range from mapping to corporate logistics to academic research, but there may be long-term uses that no one has yet foreseen.

Military satellites with even higher resolution are already in operation, but the commercialization of the technology means that spies won’t be the only ones keeping a close eye on us from above. Until now, images approaching this resolution could be captured only by aircraft, which is far more expensive (for now, at least).
