Like any lake, Australia's largest lake, Lake Eyre, fills and empties in a cycle. Usually it happens so slowly that you don't notice it, but what if you could watch five years of tidal activity in one minute, all taken from space? One Aussie Redditor has combined all the images from the Terra EOS AM-1 satellite taken since 2008 to cram it into one awesome minute.
Here's how they did it:
The images are from the Moderate-resolution Imaging Spectroradiometer (MODIS) on the Terra. The images are stored on the RapidFire service, where they can be downloaded by anyone who wants them. I wrote a script to fetch the images, throw away the more cloudy ones, crop out the Lake Eyre section from the original swathe and put the date stamp in the corner. Put the resulting 1,876 images into a video and voila! I love the 21st century....
So do we. Nice one! [Reddit Australia]
