DigitalGlobe's new high-resolution earth-imaging products and service providers have returned the first images of the Earth, and Google users can see a clearer world through Google Maps.

The photos used by Google Maps are provided by DigitalGlobe. As the new photos have been returned to Earth, users see the world through Google Maps will be more clear.

DigitalGlobe has begun collecting data from WorldView-4 satellites it launched on 11 November. The satellite was sent back to the first batch of photos taken in November 26, the shooting goal is Shibuya, Tokyo, Japan National Yoyogi complex gymnasium.

Previously, only the military and intelligence agencies have both the use of satellite photos of the qualifications and financial resources, and now business users are beginning to enjoy such resources. The use of these satellite photos widely, such as construction site planning, agriculture, scientific research and so on. Satellite photos can even help you find parking spots.

The commercialization of satellite photos has spawned many new industries and enterprises. DigitalGlobe emphasizes that while these are high-resolution photos, they are quickly captured and generated, allowing customers to wait for a day to get high-resolution satellite photos of any location on the planet.

As you might expect, WorldView-4 cameras are not only far superior to cameras on smartphones, but also to professional photographers who specialize in wildlife. WorldView-4 satellite-equipped SpaceView 110 camera is made by the defense, aviation and communications company Harris (Harris), weighing about 550 kilograms, about the equivalent of six professional wrestlers weight total.

The SpaceView 110 camera can magnify a target many times through a mirror-based design, which is like a super telescope, not just a set of telephoto lenses. Its high precision, you can at a distance of 617 km from the surface of the satellite orbit to capture the smallest surface of 0.31 meters of detail. In other words, it can clearly capture a person standing on the surface of the earth's foot.

But sites such as Google Maps and Bing Maps offer satellite photos for free, primarily through mobile or web applications, and are not qualified or required to provide the finest images. Microsoft, Apple and Facebook are also customers of satellite imagery. But not all of these companies will use satellite photos, Google and Microsoft previously used the photo is taken from a high-altitude aircraft, the high-altitude aircraft to obtain the photos are not only higher resolution and cost is relatively low, but cover Of the surface area is not large.

The SpaceView 110 camera sees more than the human eye. For example, it can collect infrared images to help firefighters find fire in smoke or help farmers check for minor changes in crop leaves.

It is worth mentioning that, WorldView-4 does not need to wait for the shooting target through it when the bottom can shoot, it can use the gyroscope to rotate, you can adjust the shooting direction. It can also move quickly, for example, it takes as long as 20 seconds to the shooting angle from Los Angeles to Las Vegas.
