Earth Timelapes

Description of Earth Timelapes

Earth Timelapse is a global, zoomable video that lets you see how the Earth has changed over the past 34 years. it is made from 35 cloud-free annual mosaics, one for easch year from 1984 to 2018, which are made interactively explorable by Carnegie Mellon University CREATE Lab's Time Machine library, a technology for creating and viewing zoomable and pannable timelapses over space and time.
using Earth Engine, we combined over 15 million satellite images acquired over the past three decades by 5 different satellites. The majority of the images come from Landsat, a joint USGA/NASA Earth observation program that the observed the Earth since the 1970s. For 2015 through 2018, we combined Landsat 8 imagery with imagery from Sentinel-2A, part of the European Commission and European Space Agency's Copernicus Earth observation program.

Timelapse is an example that illustrates the power of Earth Engine's cloud-computing model, which enables users such as scientists, researchers, and journalists to detect changes, map trends, and quantify differences on the Earth's surface using Google's computational infrastructure and the multipetabytes Earth Engine data catalog.
