“A growing archive of Landsat images allow us to see how quickly icesheets are changing.”


“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 undoubtedly transformed our ability to understand urbanization processes and how cities expand and evolve… the multi-spectrality of Landsat, its relatively high spatial resolution, its revisit period, and especially the long observational record that made millions of scenes publicly available, make Landsat a key asset for the research community.”


“Our research would not have been possible if it weren’t for decades of reliable Landsat data to help us look back in time. We hope these findings will encourage people to not only mitigate the effects of increased wildfire activity, but also to limit emissions and curb global warming.”


“With a launch in 2023, Landsat 9 would propel the program past 50 years of collecting global land cover data. That’s the hallmark of Landsat: the longer the satellites view the Earth, the more phenomena you can observe and understand.”


“In a world of scarce resources, there are distinct tradeoffs in costs and benefits of land use, and whether to conserve or convert forest to cropland. Map-based images are perhaps one of the most succinct means of helping policymakers digest complex ideas of social and economically driven environmental change.”


“By unleashing the power of our vast and open data resources, the Climate Data Initiative helps spark private sector innovation and will leverage resources for those on the front lines who are dealing with climate change. We are pooling into one place data from across the federal government to make it more accessible to the public and we hope our efforts will inspire other countries to follow suit.”


“Landsat 8 global ice mapping is enabled by its better data acquisition rate.”


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


“We are now beginning to see that the combination of high performance computing, data storage facilities, data preparation techniques, and advanced systems can materially accelerate the value of Landsat data.”


“The Landsat satellites have provided an unprecedented volume of high quality medium-resolution imagery spanning more than 30 years. Without this record it would be exceedingly difficult to place presently observed changes in ice discharge into a longer-term context.”


“Since the first in the line of Landsat craft entered orbit in 1972, this satellite program has proven valuable to the economy of the United States.”


“There is a sensor in the Landsat satellite which measures the intensity of the reflected radiation back into space. What if we could use satellite imagery from the Landsat program to find fossils?”


“Because Landsat’s been operating for so long—thermal imaging has been enabled since the 1980s—we can study how patterns in water use have changed over the landscape over long periods of time as the climate has changed and as land use patterns have changed. So Landsat has been really a critical sensor for our work.”


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


“When the archive was opened, there were more Landsat images outside it than in it. Many images were retained by the global network of receiving stations. An effort to consolidate these has added more than 3 million images to the repository since 2010; agreements are in place for a further 2 million to be ingested.”


“We are learning more about cool things to do with Landsat at a faster rate than anytime in the past.”


“In order to produce a rock outcrop map for the entire Antarctic continent, we required a freely available georeferenced multispectral dataset. The dataset needed to cover the high latitudes; be recently acquired; be of a high enough resolution to identify individual outcrops and geomorphological features; and have suitable coverage of the continent. On this basis, the Landsat 8 multispectral satellite data was chosen for analysis as no other platform met these requirements. It would not ha…


“Even though I have a book coming out about the Moon Landing, I’ll say it: Landsat is likely the greatest, most impactful, yet under-appreciated, accomplishment of the entire space age.”


“The most unique thing about Landsat is its length of record… The ability to go back 30 years or more is something you just can’t do with any other sensor.”


“Having Landsat 9 in progress, and a long-term commitment to sustainable land imaging, is great for natural resource science and for data-driven industries such as precision agriculture and insurance.”


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


“There are more than 800 billion Landsat-derived pixels of land in our imagery. If we printed out just our Landsat-based world map at poster resolution, it would cover two acres.”

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.
