LCLUC Scientists map the historical Land Cover and Land use changes using the Corona Imageires. Imagery from the Cold War’s Corona satellites is helping scientists fill in how we have changed our planet in the past half-century. To map a landscape’s history, foresters long depended on maps and traditional tree inventories that could be riddled with inaccuracies. But now they have a bird’s-eye view that is the product of a 20th-century American spy program: the Corona project, which launched classified satellites in the 1960s and ’70s to peer down at the secrets of the Soviet military. In the process, these orbiting observers gathered approximately 850,000 images that were kept classified until the mid-1990s.
