Keeping Earth. Three years ago we introduced a cloud-free mosaic of the world in Google Earth. Today we’re rolling out an even more beautiful and seamless version, with fresh imagery from Landsat 8 satellite and new processing techniques for sharper images than ever before. But not always over the same place, so we looked at millions of images and took the clearest pixels to stitch together this cloud-free and seamless image.Keeping Earth Screen Shot at

Landsat 8, which launched into orbit in 2013, is the newest sensor in the USGS/NASA Landsat Program—superior to its predecessors in many ways. Landsat 8 captures images with greater detail, truer colors, and at an unprecedented frequency—capturing twice as many images as Landsat 7 does every day. This new rendition of Earth uses the most recent data available — mostly from Landsat 8 — making it our freshest global mosaic to date. Keeping Earth Screen Shot atIn the new view of New York City, details like skyscrapers, building shadows, and baseball and softball fields in Central Park shine through.   Today we’re rolling out an even more beautiful and seamless version, with fresh imagery from Landsat 8 satellite and new processing techniques for sharper images than ever before.Keeping Earth Screen Shot atToday we’re rolling out an even more beautiful and seamless version, with fresh imagery from Landsat 8 satellite and new processing techniques for sharper images than ever before. More than 700 trillion. individual pixels—to choose the best cloud-free pixels.

Processing imagery with Earth Engine. But not always over the same place, so we looked at millions of images. And took the clearest pixels to stitch together this cloud-free and seamless image. 

 

 To produce this new imagery. We used the same publicly available. Earth Engine APIs that scientists use to do things like track global tree cover, loss, and gain; predict Malaria outbreaks; and map global surface water over a 30 year period.

Like our previous mosaic. We mined data from nearly a petabyte of Landsat imagery—that’s. More than 700 trillion. individual pixels—to choose the best cloud-free pixels. To put that in perspective. 700 trillion pixels is 7,000 times more pixels than the estimated number of stars in the Milky Way Galaxy. Or 70 times more pixels than the estimated number of galaxies in the Universe. Keeping Earth.

Open data is good for everyone To put that in perspective. 700 trillion pixels is 7,000 times more pixels than the estimated number of stars in the Milky Way Galaxy. Or 70 times more pixels than the estimated number of galaxies in the Universe.

Landsat program and its commitment to free and accessible open data. Landsat, a joint program of the USGS and NASA. Has observed the Earth continuously from 1972 to the present day. And offers a wealth of information on the changes to the Earth’s surface over time. And it’s all available in Earth Engine!

 

The new imagery is now available across all our mapping products. To check it out, open up Google Earth, or turn on the satellite layer in Google Maps. Keeping Earth.

Google Mapping Only clear skies on Google Maps

Google Mapping Only clear skies on Google Maps and Earth

June 26, 2016
To celebrate the sunny days of summer (in the northern hemisphere at least). We’re unveiling new satellite imagery for all Google mapping products today. This stunning new imagery of the earth from space virtually eliminates clouds, includes refreshed imagery for regions of the world where high-resolution imagery is not yet available. And offers a more comprehensive and accurate view of the texture of our planet’s landscape. Google mapping 2

The new, even more beautiful global view in Maps and Earth.

In 2002 NASA released the Blue Marble, a global image of the earth with a resolution of one kilometer per pixel, based on data from NASA’s MODIS instrument. Updated in 2005 to twice the resolution, it has remained the canonical globally-uniform picture of the earth for over a decade.

With the Blue Marble as inspiration, we used Google Earth Engine technology to mine hundreds of terabytes of data from the USGS’s and NASA’s Landsat 7 satellite. The result is a seamless, globally-consistent image of the entire planet with a resolution of 15 meters per pixel, far finer than is possible with MODIS data alone.

To get a feel for the difference, here’s a comparison of the Grand Canyon, first from the Blue Marble Next Generation (courtesy NASA’s Earth Observatory), and then in our new Landsat-based imagery.Google mapping

The Grand Canyon, as seen by MODIS and by Landsat 7.

The Landsat 7 satellite suffered a hardware failure early in its life that introduced striped artifacts into all of its images. By analyzing a large number of images we were able to virtually eliminate these stripes, as well as clouds and other atmospheric effects. The process was very similar to how we produced theglobal time-lapse imagery of the earth that we released last month. Google mapping castellon

Castellón, Spain: One example Landsat 7 image, and the final combined image.

The resulting 800,000 megapixel global image is so big that if you wanted to print it at a standard resolution of 300 dots per inch. You would need a piece of paper the size of a city block! Google mappingGoogle mapping south america

Northwestern South America: before and after.

Mining data from a large number of Landsat images of each area allowed. Us to reconstruct cloud-free imagery even in tropical regions that are always at least partly cloudy. Google mapping papua

Central Papua, Indonesia: before and after.

We prioritized recent data when it was available. So this update also includes refreshed imagery in many regions of the world. Especially in areas where high-resolution imagery is not available. Including parts of Russia, Indonesia, and central Africa. Google mappingGoogle mapping saudi arabia

Agricultural expansion in Saudi Arabia: before and after.

This new picture of the earth also reveals the texture of the landscape with greater clarity than ever before. Google mapping brazil deforestation

Continuing deforestation in Brazil: before and after. Google mapping

We’re proud of the progress we have made, but there is always room to keep improving. For example, although we have tried to minimize the impact of the stripe artifacts in the Landsat 7 images. They are still visible in some areas. There is more good news though: the new Landsat 8 satellite. Launched earlier this year, promises to capture even more beautiful and up-to-date imagery in the months and years ahead.

You can see our new satellite imagery by going to Google Maps and turning on satellite view. Or by launching Google Earth. And zooming out. Have fun exploring!

Street View Dubai Drive by Dubai

Street View Dubai Drive by Dubai with Street View

 Street View Dubai December 8, 2014
Dubai is home to the world’s tallest tower. Street View Dubai Largest mall and the planet’s only seven-star hotel. With all these modern wonders, it’s no surprise that Dubai hosted 10 million global visitors last year—and aims to hit a record-breaking 20 million visitors in 2020. Starting today. It can add virtual visitors to that list, as Dubai becomes the first city in an Arab country to be added to Street View in Google Maps. Street View Dubai

Start your tour with a drive on Sheikh Zayed Road. Street View Dubai the longest road in the Emirates that runs in parallel to the coastline. Peer up at the city’s iconic skyscrapers and high-rise towers that. In some cases, reach more than 1,000 feet into the clouds. On one side, you can see the city’s elevated and driverless metro system. earthtopomaps.com

Along Financial Road. Pass Dubai Mall, home to thousands of shops. But with an average of 75 million visitors every year. The mall is more than just a retail space. Inside is a 10 million-liter aquarium — one of the largest suspended tanks in the world. — and a facing it there is a flock of famous dancing fountains.

It’s hard to believe that a city not much larger than 4,000. square kilometers has become such a hub of modern culture with more than 200. nationalities mingling daily. As well as a center for trade and tourism in just four short decades. We hope that you’ll be inspired to explore its wonders in person, but until then. They’re just a click away. Street View Dubaistreet view Dubai Screen Shot at
Most of Dubai’s buildings were constructed in the last decade. But if you’re curious to go back to where it all began. vVsit Deira. Here, the great-grandfathers of present-day merchants set up shop. Creating one of the region’s biggest markets and establishing a major link in the time’s global trade routes.

Finally, no visit of Dubai is complete without touring the Dubai Creek. Known for its fusion of past and present cultures, and its trading connections with countries around and beyond the Arabian Gulf. Along its banks you can see merchant dhows docked and bazaars bustling with silks and spices.
