An eye on habitat change
Terra-i is an artificial intelligence program that uses real-time rainfall data to predict how green a given habitat should be. It then matches that prediction against images of the habitat from an Earth-monitoring satellite. Differences in greenness between what is predicted and what is observed – right down to the pixel – suggest habitat conversion by human activity.
What’s really clever is that terra-i ‘learns’ as it analyses, using a neural network to ‘learn’ which actual levels of greenness go with which amounts of precipitation during the year. The result allows conservationists a view of forests and other habitats across an entire continent.
