See Saudi development Researchers at Carnegie Mellon University's Robotics Institute, working with colleagues at Google and the US Geological Survey (USGS), have adapted their technology for interactively exploring time-lapse imagery to create a tool that enables anyone to easily access 13 years of NASA Landsat images of the Earth's surface. This new capability within the Google Earth Engine enhances the public's ability to view the massive amount of imagery collected by the Landsat program between 1999 and 2011. Users can zoom in or out on any spot on the globe and move back and forth in time. This enables anyone to see deforestation unfold in the Amazon, observe water levels fall in the Aral Sea and watch the urbanization of desert as the city of Riyadh expands. Time-explorable Earth is available only through Chrome and Safari browsers. Videos demonstrating the time-lapse tool can be viewed at http://earthengine.google.org/#intro.
