Google launches mapping tool to monitor global environmental change

The search giant’s philanthropic arm, Google.org, calls the new Google Earth Engine “a planetary-scale platform for environmental data and analysis.” It combines Google Earth’s maps with 25 years’ worth of Landsat satellite images and other data.

Just as important as that data goldmine is Google’s move to put its immense computing resources at scientists’ disposal. Google.org is donating 20 million computational hours over the next two years to developing countries so they can monitor their forests as the United Nation’s prepares to implement an initiative called REDD, Reducing Emissions from Deforestation and Forest Degradation in Developing Countries.

“Deforestation releases a significant amount of carbon into the atmosphere, accounting for 12-18 percent of annual greenhouse gas emissions,” Rebecca Moore, the engineering manager for Google Earth Engine, wrote in a blog post. “For the least developed nations, Google Earth Engine will provide critical access to terabytes of data, a growing set of analytical tools and our high-performance processing capabilities.  We believe Google Earth Engine will bring transparency and more certainty to global efforts to stop deforestation.”

For instance, scientists processed 8,000 Landsat satellite images on Google Earth Engine to create a map of the Democratic Republic of the Congo that shows the loss of forest cover over the past decade.

Scientists also used more than 53,000 satellite images taken between 1984 and 2010 to develop an extremely detailed forest cover and water map of Mexico. The Google Earth Engine tapped 1,000 servers to perform the 15,000 hours of computation needed to create the map in less than a day.

“As we fully develop the platform, we hope more scientists will use new Earth Engine API to integrate their applications online — for deforestation, disease mitigation, disaster response, water resource mapping and other beneficial uses,” Moore wrote. “We look forward to seeing what’s possible when scientists, governments, NGO’s, universities, and others gain access to data and computing resources to collaborate online to help protect the earth’s environment.”

Wonderfully brilliant use of technology to achieve something useful! Thank you Google and UN for working together to bring this to the world! Thanks to Reuters for the reporting!
