First images from new satellite, Google maps more clearly in the eyes of the world-IT information

According to foreign media reports, the commercial high-resolution Earth imaging products and services supplier DigitalGlobe new satellite back to the first Earth Google Google Maps users can see the world more clearly.

Photos for Google Maps is provided by DigitalGlobe. New pictures have been transmitted back to Earth, and Google Maps users see the world more clearly.

DigitalGlobe has started collecting data from the WorldView-4 satellite launched on November 11. The satellite sent back the first photo was taken on November 26, shooting the target is Japan, Shibuya, Tokyo's national Yoyogi sports arena.

Previously, only military and intelligence authorities both eligibility to use satellite photos and financial resources, business users now have begun to enjoy these resources. These satellite photos of a wide range of uses, such as building site planning, agriculture, scientific research, and so on. Satellite images can even help you find a parking place.

Commercial satellite photos has spawned many new industries and businesses. DigitalGlobe stressed that although this is a high resolution photo, shot and build quickly, customers only need to wait a day to access to any place on Earth in high resolution satellite images.

If you want, WorldView-4 satellite is equipped with cameras not only is far superior to the Smartphone's camera, but also special camera for professional photographers shoot wild animals and plants also can't compare. SpaceView 110 of the WorldView-4 satellite is equipped with cameras were from the defense, aerospace and communications company Harris (Harris) manufacturing, weighing about 550 kg, roughly equivalent to 6 professional wrestler's weight combined.

SpaceView 110 cameras through a mirror-based design will target magnified many times, which is like a very large telescope, rather than a head of Prime lenses. Its high shooting accuracy can be captured on the surface of 617 km orbit to the ground minimum details of 0.31 m. In other words, it can shoot clearly standing on the Earth's surface a person on foot.

But website like Google Maps and Bing Maps through mobile applications or Web applications to provide free satellite photos, they are not eligible and there is no need to provide the most precise images. Microsoft, Apple and Facebook are customers of the satellite image. But not all of these companies are using satellite images, Google and Microsoft's previous photo was taken from a high altitude aircraft available, this photo obtained by flying jets shot not only better resolution and relatively low cost, covers little surface area.

SpaceView 110 cameras see more than the human eye. For example, it can collect infrared images to help fire-fighters found in the smoke from fires, or helping farmers to check small changes in crop leaves.

It is worth mentioning that WorldView-4 does not need to wait for shots when shooting below the goal after it, it can make use of a gyroscope to rotate or adjust the direction. It can move quickly, for example, it takes 20 seconds to move from Los Angeles to Las Vegas City perspective.

新卫星发来首批照片，谷歌地图眼中的世界更清晰 - IT资讯

据外媒报道，商用高分辨率地球影像产品和服务供应商DigitalGlobe的新卫星发回了第一批地球照片，谷歌用户通过Google Maps可以看到更清晰的世界了。

Google Maps所用的照片是由DigitalGlobe提供的。由于新照片已经传回地球，用户通过Google Maps看到的世界将更加清晰。

DigitalGlobe已经开始收集由它在11月11日发射的WorldView-4卫星发回的数据。这颗卫星发回的首批照片是在11月26日拍摄的，拍摄目标是日本东京涩谷区的国立代代木综合体育馆。

以前，只有军方和情报机关才兼具使用卫星照片的资格和财力，现在商业用户也开始享受这类资源。这些卫星照片的用途广泛，比如建筑场地规划、农业、科学研究等等。卫星照片甚至还能帮你找到停车地点。

卫星照片的商用化催生了很多新的行业和企业。DigitalGlobe强调说，虽然这都是高分辨率的照片，但是拍摄和生成的速度很快，客户只需等待一天就能获得地球上任何一处地点的高分辨率卫星照片。

如你所想，WorldView-4卫星配备的摄影机不但远远优于智能手机上的摄像头，而且连专门拍摄野生动植物的专业摄影师所用的照相机也无法与其相提并论。WorldView-4卫星配备的SpaceView 110摄影机是由国防、航空和通讯公司哈里斯（Harris）制造，重约550公斤，大约相当于6名职业摔跤运动员的体重总和。

SpaceView 110摄影机可以通过一种基于镜子的设计将目标放大很多倍，这种设计就像一个超大型望远镜，而不仅仅是一组长焦镜头。它的拍摄精度极高，可以在距离地表617公里的卫星轨道上捕捉到地表最小0.31米的细节。换句话说，它可以清晰拍摄到站在地球表面上的一个人的一只脚。

但是像Google Maps和必应Maps这样的网站主要通过手机应用或网页应用为用户免费提供卫星照片，它们没有资格也没有必要提供最精细的影像。微软、苹果和Facebook也都是卫星影像的客户。但是并非所有这些公司都会使用卫星照片，谷歌和微软以前所用的照片就是从一架高空飞机上拍摄得到的，这种由高空飞机拍摄获得的照片不但分辨率更高而且成本相对低廉一些，但是覆盖的地表面积不大。

SpaceView 110摄影机看到的东西比人眼更多。例如，它可以收集红外线图像，帮助消防队员在浓烟中找到起火点，或者帮助农民检查农作物叶子中的细微变化。

值得一提的是，WorldView-4并不需要等待拍摄目标经过它下方时才能拍摄，它可以利用陀螺仪进行旋转，也可以调整拍摄方向。它还能快速移动，比如它只要20秒的时间就能把拍摄视角从洛杉矶市转移到拉斯维加斯市。
