More than 100 million Landsat scenes have been downloaded from the USGS since 2008, when the data became free as part of the Department of the Interior’s Open Data Policy.

Consistent collection methods provide direct comparability across decades, making it easier to detect subtle land change.

This provides the ideal scale to observe and measure human- and natural land change.

The processed data are at 30-meter resolution – meaning 1 pixel is 30 x 30 meters, roughly the size of a baseball field.

Processed Landsat data are globally recognized for their scientific quality, precision and consistency.

The Landsat imagery collection is the world’s only long-term, continuous, data record of the entire Earth’s land surfaces dating back to 1972.

Today, by leveraging digital communications, supercomputer technology, and cloud processing, USGS makes the world’s largest archive of land surface imagery accessible to anyone for free. In the past, data delivery was cumbersome, and users had to pay for access. Scientists can use Landsat’s deep historical archive to study glacial loss. Both glaciers have retreated significantly since the launch of the first Landsat satellite in 1972. This USGS Landsat 8 image shows the extent of Bear Glacier (upper) and Aialik Glacier (lower) on Alaska’s Kenai Peninsula, as of September 4, 2018. By observing phenomena that can’t be seen by the human eye, Landsat helps users identify and analyze a wide variety of critical landscape changes. Landsat’s unique multi-spectral instruments simultaneously collect visible, shortwave and thermal infrared data. The baseline configuration of two operational Landsat satellites achieves 8-day repeat coverage of any location on Earth. At an altitude of 705 km, one Landsat satellite takes 232 orbits, or 16 days, to complete global coverage. Every day, the Landsat data archive grows by about 40 million square kilometers – the size of Europe and North America combined. These substantial investments, measured in tens of billions of dollars, have created a Landsat archive containing nearly 300 billion square kilometers of global imagery. Government investment in Landsat observations and data distribution. The content served by 3D Timelapse is derived, in large part, from five decades of U.S. Landsat is Indispensable for Google Timelapse

The videos will be available for free download in ready-to-use MP4 format. Google is also releasing more than 800 time-lapse videos covering more than 300 locations on YouTube. Or open Google Earth and click on the ship’s wheel to find interactive guided tours of the new imagery and featured locations.

You can use the search bar to choose any place on the planet where you want to see the changes over time in motion. To explore Timelapse in Google Earth, go to g.co/Timelapse. Google partnered with Carnegie Mellon University’s CREATE Lab to create five thematic “Earth Voyager” stories that users can explore through guided tours:

Landsat’s spectral bands allow researchers to see photosynthetic activity that is invisible to the naked eye. USGS Landsat 8 image showing algal bloom in Lake Erie in September of 2017. None of this would have been possible without the help of USGS: The data from USGS/NASA Landsat satellites have been the major source for the global imagery behind the Google Earth application, including this new feature. The new Timelapse tool allows researchers, educators, nonprofits, governments, and the world-wide community to access powerful 3D visuals to study our planet’s stories and consider actions regarding climate change, sustainable development and much more. Now anyone can watch time unfold across the globe and witness nearly four decades of planetary change. With Timelapse in Google Earth, 20 million satellite photos from the past 37 years have been embedded into Google Earth, allowing users to explore changes to our planet's surface over time.

In the biggest update to Google Earth since 2017, you can now see our planet in an entirely new dimension: time. The USGS, along with NASA, the European Commission, and the European Space Agency, has been critical in the provision of imagery for this new version of Google Earth Timelapse that shows visual evidence of global changes spanning nearly 40 years.
