EL paso del tiempo y su impacto en la tierra.

Las nuevas tecnologías de la imagen (como: Timelapse) nos permiten ver en pocos segundos lo que ha ocurrido en largos periodos de tiempo vean este fascinante trabajo que está haciendo la NASA, con Google y los datos de la encuetsa de geolocalización de U.S.A así como el CREATE Lab de Carnegie Mellon University

A Terrifying, Fascinating Timelapse of 30 Years of Human Impact on Earth

A new interactive project from Google, NASA and the US Geological Survey.

Since the 1970s, NASA and the U.S. Geological Survey have been amassing satellite images of every inch of our planet as part of the Landsat program. Over time, the images reveal a record of change: of cities expanding, lakes and forests disappearing, new islands emerging from the sea off the coast of rising Middle East metropolises like Dubai.

If you could thumb through these historic pictures as if in a flip book, they would show stunning change across the earth’s surface, in both our natural environments and our man-made ones. Now, the digital equivalent of that experience is possible – three decades of global change as GIF – in a project unveiled today between NASA, the USGS, TIME, Google, and the CREATE Labat Carnegie Mellon University.

Landsat images taken between 1984 and 2012 have been converted into a seamless, navigable animation built from millions of satellite photos. As Google wrote this morning on its blog: “We believe this is the most comprehensive picture of our changing planet ever made available to the public.”

Below are a few of the GIFs Google has created showing some of the most startling pockets of change:

You can also zoom in to any spot on the planet – your hometown, the Amazon, your favorite Chinese mega-city – and watch the same three-decade timelapse unroll. Good luck getting anything done for the rest of the day.
