D)Google Mapping clear skies 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 clear skies

E)Google Mapping clear skies The new, even more beautiful global view in Maps and Earth.

Google Mapping clear skies 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.

F)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 clear skies

The Grand Canyon. As seen by MODIS and by Landsat 7.

G)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 timelapse imagery of the earth. That we released last month. google mapping clear skies

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

H)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 clear skies

Northwestern South America: before and after.

I)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 clear skies

Central Papua, Indonesia: before and after.

J)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 clear skies

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 clear skies

Continuing deforestation in Brazil: before and after. Google mapping

K)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!

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. That’s a loss of forested land comparable in size to the entire state of Alaska.

C)Google Earth Engine Global Forest Bring Forests are the mighty lungs of our planet. They absorb carbon dioxide. And emit oxygen on which all people and animals on Earth rely. For the sake of our future, it is critical that all people. Including the next generation, understand our global forests in order to manage them sustainably.

Today, Science in the Classroom,Dr. Matt Hansen of the University of Maryland. And Google Earth Engine are presenting. Global Forest Change Explorer to help engage young people in forest conservation.

D)Global Forest Change Explorer website contains maps that are available for interactive analysis as well as an accompanying activity worksheet. Explorer Tool relies on open data that is used by remote sensing and. GIS professionals in their work.google earth engine global forest bring

E)Fly to different parts of the world and compare data.
A number of years ago. Dr. Matt Hansen and a team of researchers at the University of Maryland turned to. Google Earth Engine to map high-resolution global forest cover with. Earth Engine’s cloud-based image processing and computing. The team mapped global forest loss and gain from 2000 to 2012 at 30-meter resolution for the entire globe. In 2013, the methods and results were published in Science Magazine and online for everyone to explore. These findings are now an important part of the website. Global Forest Watch. Which gives governments and decision makers free access to the data and tools required to monitor and manage their forests.google earth engine global forest bring

F)Dr. Matt Hansen presenting at the World Economic Forum.
Science in the Classroom. (SitC) thought this was great research to bring into the classroom and make available to anyone online. SitC packages annotated research papers with supplemental teaching materials to help pre-college.

And college students understand the structure and workings of scientific research. SitC and Google Earth Engine built the. Global Forest Change Explorer to make. Dr. Hansen’s data accessible to a younger audience.

G)Annotations provide supplemental context to. Dr. Hansen’s paper
We live in a dynamic world where the pressures of population growth increasingly impact and threaten our forests. Educators can easily flip their classrooms into science labs by combining SitC materials with. Global Forest Change Explorer.
