我们最伟大的创新之一是我们能够从太空俯瞰我们的星球。从地表数百英里之上,我们可以看到一切如何结合在一起。我们可以看到数百万年来土壤的侵蚀,以及在水的存在下涌现的生命。我们也看到人类的实验在田野和平原、沿着河流和海洋展开。从那里俯瞰,我们的印记以灰色有机体的形式留在地球上,混凝土和钢铁的有机体生长和蔓延,填满山谷,点缀山脊。在远离城市中心数英里的地方,也发现了我们存在的其他迹象:森林被砍伐,湖泊被耗尽。

谷歌的地球引擎项目让我们看到这些变化随着时间的推移而发生。谷歌重点展示了地球表面八个地点的变化:蓬勃发展的拉斯维加斯市、遍布怀俄明州的煤矿、沙特阿拉伯的灌溉、伊朗的乌尔米耶湖干涸、亚马逊雨林的森林砍伐、哥伦比亚冰川的退缩、迪拜的沿海扩张以及咸海的干涸

遗憾的是,我无法嵌入地图视图,但我确实找到了延时摄影的动画GIF

每个30米分辨率的延时摄影帧都是一个1.7太像素的合成图像,由1984年至2012年间捕获的全球年度陆地卫星图像构建而成。

最酷的部分是延时摄影是交互式的,因此您可以缩放和平移地球。我查看了德克萨斯州奥斯汀,并观看了道路和社区的大规模扩张。如果您点击此链接,您也可以看到。

我想知道:您发现了什么有趣的东西?
