It's good to see that Google.org is still alive and kicking, despite all the rumours about its inevitable demise. Their new project - aimed at
helping to visualize and then crowdsource the online monitoring of deforestation - is not only impressive, but also very timely:
In Google.org's prototype software, environmental authorities or NGOs interested in monitoring forests start with satellite images of their area and track how the size and shape of the tree cover has changed over time. The software can processes the images to extract useful scientific and tracking information about how much the forests have changed.
For the analysis, the Google.org team worked with Greg Asner of Carnegie Institution for Science and Carlos Souza of Imazon. Technology developed by Asner and Souza is used in Latin America to track changes in forest cover – but mainstream use of the models has been slow due to lack of access to high-quality satellite images and the computer power needed to carry out the analysis.
Google.org's solution is to enhance the Asner and Souza models using its own computing power. "What if we could gather together all of the earth's raw satellite imagery data – petabytes of historical, present and future data – and make it easily available on this platform? We decided to find out, by working with Greg and Carlos to re-implement their software online, on top of a prototype platform we've built that gives them easy access to terabytes of satellite imagery and thousands of computers in our data centres," it wrote.
It also seems like a smart way to put all those idle computers in Google's network to a good use.
