“Landsat provides a very good coverage of Amazonia both spatially and temporally. We have known for some time already that the Landsat images can be used to identify ecologically relevant environmental and biotic variation in Amazonian rainforests, but this is the first time we use satellite images to actually predict species distributions.”
“...Landsat and Copernicus, the best two examples of government satellite programs that have positively impacted global development as result of their free and open data policy.”
"The Landsat program is one of the world’s greatest open data success stories. Landsat satellites have been orbiting the earth for decades, creating an irreplaceable archive for studying questions ranging from the retreat of the Aral Sea to water quality in Iowa."
“That’s the beauty of Landsat—it allows us to quantify these spatial patterns that are of high interest to water managers.”
"Another landmark program within USGS is called Landsat... USGS made a decision...to be able to open up that data, make it free, and the scientific discoveries, the articles, the access, the utility of that data just went absolutely through the roof. So it's been a really wonderful story about how opening up scientific data allows more discovery, gets people more excited... We really do try to put our data out there in a way that it is usable by the most amount of people as possible."
