“NASA’s comprehensive study of Earth has provided much of the underlying understanding of current trends in the planet’s climate – including definitive measurements of rising sea levels, glacier retreat, ice sheet changes and the decline in the volume of the Arctic sea ice cap. Our satellites have provided global, long-term views of plant life on land and in the ocean. And our supercomputing power is allowing us to better understand how all the parts of the Earth system work together and he…

“Landsat is the crown jewel of Earth Observation datasets—unique 40+ year archive.”

“Landsat is an invaluable tool for people working in our field of community wildfire safety.”

“I am a big fan of Landsat 8 satellite images as a resource when making maps.”

“The novelty of our study lies in the bigger picture—measuring glacier change over all main glaciated ranges in Bolivia—and in the identification of potentially dangerous lakes for the first time.”

“We basically built … Tinder for Landsat maps: Swipe right if it’s good, swipe left if it’s bad.”

“As we continue the work to understanding our planet in the face of climate change, Landsat’s unique data and record of our changing Earth has proven invaluable,”

“The data policy for Landsat was a paradigm shift for the world. There is no doubt about it.”

“The Landsat collection 1 datasets represent a milestone in remote sensing science, with comparatively stable radiometric calibration and atmospheric correction.”

“Landsat 9 is really a land imaging cornerstone in guaranteeing that we’ll continue to have the types of surface measurements that we’ve had for nearly 50 years, and I think that’s significant. The user community that has developed science and application advancements around Landsat 8 will now get two observatories that are nearly identical, and we can expect to have a high-quality and reliable data stream for the next 10-plus years while Landsat continues to evolve into the future.”

“Landsat 8 imagery is an incredibly powerful resource. It is some of the most valuable open data produced by the US Government. Our partners rely on Landsat data for everything from evaluating droughts to tracking conflict.”

“With Landsat we can see temperature of individual fields and how it varies from field-to-field. The temperature of the land surface gives us a good indication of how rapidly water is evaporating off that surface. And this is really important for knowing how healthy the crops are and also for supplying information for irrigators: how much water was used last week and how much do they need to replenish in the current week to keep the crops healthy.”

“[T]he case for open data is more than proven by Landsat and Copernicus. Many innovative applications using these datasets are the dividends that benefit the taxpayer.”

“Landsat data are a key climate data source. That’s true for vegetation, for the carbon cycle, and it’s true for the cryosphere.”

“Until we made the map of coral reefs with Landsat 7, global maps of reefs had not improved a lot since the amazing maps that Darwin drafted.”

“Landsat has been producing Big Data since before data was big.”

“With these new [Landsat] data, we can begin to unravel the mechanisms by which the ice flow is speeding up or slowing down in response to changing environmental conditions.”

“A sizable portion of our greenhouse gas contribution to the atmosphere comes from land use. And having Landsat data to look back to the 1970s, from there to now, you can then calculate or approximate year-by-year what that contribution is, and that’s extremely important.”

“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.”

“Landsat and SRTM are my eyes on the ground. Without them I am totally blind. They are great gifts to humanity.”

“By using Landsat 8 imagery, and classification tree analysis, which is an advanced artificial intelligence routine, we have been able to construct a reliable classification system to identify cheatgrass infestations that is accurate. This has implications for fire susceptibility. Cheatgrass is driving wildfire on rangelands and we need to identify areas that have heightened susceptibility to wildfire.”

The NASA/USGS Landsat Program provides the longest continuous space-based record of Earth’s land in existence. Landsat data give us information essential for making informed decisions about Earth’s resources and environment.
