Timelapse Google Earth Engine

A)Timelapse Google Earth Engine. B)Timelapse Google Earth Engine. In 2013, we released Google Earth Timelapse, our most comprehensive picture of the Earth’s changing surface. This interactive experience enabled people to explore these changes like never before—to watch the sprouting of Dubai’s artificial Palm Islands, the retreat of Alaska’s Columbia Glacier and the impressive urban expansion of Las Vegas, Nevada. Today, we’re making our largest update to Timelapse yet, with four additional years of imagery, petabytes of new data, and a sharper view of the Earth from 1984 to 2016. We’ve even teamed up again with our friends at TIME to give you an updated take on compelling locations.

C)Leveraging the same techniques we used to improve Google Maps and Google Earth back in June, the new Timelapse reveals a sharper view of our planet, with truer colors and fewer distracting artifacts. A great example of this is San Francisco and Oakland in California:

D)There’s much more to see, including glacial movement in Antarctica, urban growth, forest gain and loss, and infrastructure development:.

E)Using Google Earth Engine, we sifted through about three quadrillion pixels—that’s 3 followed by 15 zeroes— from more than 5,000,000 satellite images for this latest update, we had access to more images from the past, thanks to the Landsat Global Archive Consolidation Program and fresh images from two new satellites, Landsat 8 and Sentinel-2.

F)We took the best of all those pixels to create 33 images of the entire planet, one for each year  we then encoded these new 3.95 terapixel global images into just over 25,000,000 overlapping multi-resolution video tiles. Made interactively explorable by Carnegie Mellon CREATE Lab’s Time Machine library. A technology for creating and viewing zoomable and pannable timelapses over space and time.

G)To view the new Timelapse, head over to the Earth Engine website. You can also view the new annual mosaics in Google Earth’s historical imagery feature on desktop, or spend a mesmerizing 40 minutes watching this YouTube playlist. Happy exploring! Landsat imagery courtesy of NASA Goddard Space Flight Center and U.S. geological Survey images also contain modified Copernicus Sentinel data 2015- 2016.                                                                                                         earthtopomaps

Mississippi river flooded

A)Mississippi river flooded

C)Mississippi river flooded. In 1926, the Mississippi river flooded to its highest level in history, destroying towns and leaving hundreds of thousands homeless. Since then, dams and thousands of kilometers of levees have been built to control the mighty Mississippi. 60 years on, another effect of the historic flood is becoming apparent. As the river has become calmer. It now also carries a lot less of the sediment that created and replenished the delta. Without that. More than 13 thousand square kilometers of the delta — an area 10 times the size of London — is slowly slipping into the Gulf of Mexico. Once again the river is threatening to displace thousands and drown the fragile delta wetlands.                                                                               mississippi river flooded

The change of the Mississippi over decades is just one of the hundreds of stories of similarly dramatic change around the globe; from the draining of the Aral Sea in the Middle East for crops. To the effects of dam construction in China, or the impacts of the multi-year drought on the Western U.S. Water has been shaping our planet since it was formed. And still plays a direct and crucial role in all of our lives.

It took three years to download 1.8 petabytes of data from the USGS/NASA Landsat satellite program and prepare that for analysis. Each pixel in 3 million satellite images, going all the way back to 1984. Was examined by a computer algorithm developed by the Joint Research Center running on the. Google Earth Engine platform. More than 10 million hours of computing time was needed for this, roughly equivalent to a modern 2-core computer running day and night for 600 years.

Mississippi river flooded. The results for the first time allow us to map. And measure changes in the water surface over time with a 30-meter accuracy. Month-by-month, over 32 years. Here are some of our findings:

  • 90 thousand square kilometers of water – the equivalent of half of the lakes in Europe – have vanished altogether. Over 200 thousand square kilometers of new, mostly man-made water bodies came into existence.
  • The continuing drying up of the Aral Sea in Uzbekistan and Kazakhstan accounts for the biggest loss in the world.
  • Iran and Afghanistan lost over a half, Iraq over a third of its water area.
  • Although the area covered by water in the U.S. has overall increased a little. A combination of drought. And sustained demand for water have seen six western states. Arizona. California. Idaho. Nevada. Oregon, Utah, account for a third of the loss in U.S. water surface.

The research findings and the maps. F)published today in the journal Nature, are available for you to explore on. G)This new website. The data are also freely available in Google Earth Engine for further research, use, and download. These new maps, statistics and the stories of change they reveal provide essential information which can aid global water security. Agricultural planning, disaster preparedness, public health. Climate understanding and more. Offering the most detailed view to date of one of our planet’s most vital resources.

Mapping Deforestation Time

November 14, 2013

C)We’re excited to announce today that, in a collaboration led by Dr. Matthew Hansen at the University of Maryland, we’ve built the first detailed maps of the world’s forests, from 2000-2012. Documenting and quantifying forest landscape changes such as fires, tornadoes, disease and logging.The most significant findings were that the overall rate of tropical deforestation is increasing. And global forests have experienced a net loss of 1.5M sq km during 2000-2012 due to both natural (disturbance) and human causes.

Sumatra has lost over 50% of its natural forest within the past 30 years. Click to enlarge.

E)The detailed study was published today in the journalScience, High-Resolution Global Maps of 21st-Century Forest Cover Change. Key to the study’s success was the collaboration between scientists at the University of Maryland, who developed the models to analyze Landsat satellite data, and computer scientists at Google. Who then used Google Earth Engine technology to run these models on more than 650,000 Landsat images. While the analysis would have taken a single computer more than 15 years to perform.

Here are some other notable sites:

F)Paraguay’s Chaco woodlands within the western half of the country are experiencing rapid deforestation in the development of cattle ranches. The result is the highest rate of deforestation in the world. Click to enlarge. Mapping deforestation.

G)The Siberian larch forests of Yakutia, Russia, are prone to fire during spring to early summer. Such extensive fires result in significant carbon emissions. Click to enlarge. H)Mapping deforestation.
