“Without Landsat we would not have the record we have today about deforestation and changing agriculture across a vast and important biome.”

“We like to think about Landsat as being, for this particular problem, sort of the sweet spot—the perfect asset. We found Landsat was really good at mapping the bulk of biomass for this particular test area we were looking at.”

“Science and technologies, especially satellite imagery, are absolutely essential because people’s livelihoods, natural resources, and biodiversity are connected to each other. Satellite imagery are our eyes in the sky, providing those insights and up-to-date information.”

“Landsat can see the surface—human settlements, forests, coastal systems. It helps us understand crucial areas of biodiversity on land, crop yields, how to manage our resources, how to protect them.”

“You may have heard me say this before, but I firmly believe there are few topics more fundamental to study than the workings of our planet. The earth sciences aim to unravel how the lithosphere, atmosphere, hydrosphere, and biosphere operate—and how they operate together. It is a science of synthesis. And it’s one that needs to move forward, both because of the great service the earth sciences perform for society and the understanding of world-shaping processes that they advance.”

“We’re taking darkness out of the equation. Extending the ability to observe ice and polar ocean changes increases the probability of capturing major glacier calving events, wind-driven surface melting or warming, and coastal ocean ice shelf breakup that can be expected to occur more frequently in the future if the pace of warming does not slow.”

“That’s the beauty of Landsat—it allows us to quantify these spatial patterns that are of high interest to water managers.”

“A new era of open-access satellite data has arrived. In 2008, The U.S. Geological Survey released for free to the public its Landsat archive, which dates back to the 1970s and is the world’s largest collection of Earth imagery.”
