The all-seeing eye of Google has revealed itself yet again, this time in the form of a series of animated timelapses that show how the earth has changed over the past 25 years. Google partnered with the United States Geological Survey (USGS) to collect over 900 terabytes of data from USGS’s Landsat satellite and compile the results into 25 year long time lapses. Each frame in the timelapse represents a year of satellite data in a 1.7 terapixel snapshot. Because the Landsat has been active for so long (it started recording data in 1972), Google was able to use these images to capture some truly monumental changes in the planet. Glaciers can be seen retreating in Alaska, man-made islands can be seen springing up around Dubai, and Brazil’s deforestation can be witnessed in its horrifying enormity.
