They are a breathtaking visualisation of just how quickly our planet is changing.
Google has released these astonishing images showing data collected from the Landsat satellite from 1982 until 2012.
They reveal everything from man's impact on the desert as Las Vegas expands to the retreat of glaciers in Columbia.

HOW THEY DID IT
Each frame of the timelapse map is constructed from a year of Landsat satellite data, constituting an annual 1.7-terapixel snapshot of the Earth at 30-meter resolution.
The Landsat program, managed by the USGS, has been acquiring images of the Earth's surface since 1972. Landsat provides critical scientific information about our changing planet.
Google worked with the U.S. Geological Survey (USGS), Nasa and Time to develop the images, even digitising tapes containing the early data from the satellites.
