Earth Engine Timelapse, the newest project of Google is a zoomable and searchable video on how much the world has changed in the last 30 years. It is only 30 years, because it has been possible to make professional materials with satellite photography for this long, writes

The pictures consist of 33 cloudless satellite-photo mosaics, one from each year, between 1984 and 2016. The buildings of all the larger cities can be seen by clicking on ‘play’.

The project needed 5 million satellite photos from 3 decades and 5 different satellites. The majority of the pictures are from Landsat, which is a joint program of USGS and NASA, and has been monitoring the surface of the Earth since 1970.

The photos, of course, can be zoomed or scrolled.
