“Landsat is widely considered to be a crucial national asset, comparable to the satellite-based GPS system and National Weather Service satellites. Ready access to Landsat images supplies a reliable common record of Earth conditions that fosters the mutual understanding of environmental challenges by citizens, researchers, and decision makers worldwide.”


“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 long-term acquisition plan of the Landsat mission provides a unique and invaluable dataset for tracking multi-decadal changes in the density and distribution of mangroves at continental scales.”


“The growth of open satellite-image archives such as Landsat is leading to more sophisticated data products.”


“We have brought it from the brink of death and back to life so many times over the last seven years. It’s just amazing what our flight operations team and our engineers are able to do with that spacecraft. It’s the oldest spacecraft of its type still functioning. We’ve certainly gotten our money’s worth out of it.”


“By combining the 34-year record provided by Landsat [30 m] with climate data, we can now quantify relations between water availability and vegetation dynamics in ways that were not previously possible.”


“For our main aim of quantifying surface water extent dynamics during a period of high hydro-climatic variability, Landsat was the only satellite archive to meet all our criteria.”


“Landsat is the oldest continually operated program of its kind: Its satellites have been capturing images of the Earth since the Nixon administration.”


“Many of our customers’ work couldn’t be done without Landsat.”


“We’ve got this data of every field, of every country…. the archive is just going to continue to yield good information, good science, better management, reduce costs. It’s incredible.”


“In many cases the Landsat archive has provided the only consistent source of information to monitor changes in the surface of the Earth.”


“Landsat is key to a wide range of applications that support global glacier monitoring and elucidate the impacts of global climate change.”


“This is an example of something government can do well: investing in infrastructure that broadly benefits society, and provides a stable platform for the development of businesses and economic activity. Landsat is the data equivalent of the interstate highway system, a public good that has spawned a thriving for-profit remote sensing industry in the US and beyond.”


“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.”


“I don’t think there’s any question about how important and how valuable MSS is.”


“The results of the Scopus bibliometric analysis indicate that inland water quality remote sensing has been growing dramatically since its introduction in the 1970s…The most pronounced year-on-year jump occurs right after 2008, which corresponds to the public release of freely available Landsat imagery by NASA and the US Geological Survey…This result is consistent with previous research showing that for multiple earth observation fields, the release of the Landsat archive resulted in more fr…


“We believe this type of continuous mapping of forest metrics at expansive scales would not have been possible without the excellent radiometric characteristics of Landsat 8, particularly the high level of quantization and the outstanding signal-to-noise ratio, which enables fine distinctions that were not previously possible.”


“There are roughly 400 billion land pixels in a single [Landsat] global mosaic.” (With at least one image of every location on Earth per season every year, the entire 43-year Landsat record contains more than 50 trillion pixels.)


“Without Landsat, ‘we would be flying blind. We need those eyes in the sky to complement our ground efforts.'”


“The Landsat science community is giddy at the results they’re seeing from the latest Landsat instrument. It’s that much better than the last one.”


“As a researcher with a limited budget, using the Landsat data for free made this project possible. The global geographic range together with free availability ensures that our study could potentially be repeated in other countries.”


“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.”


“Free and open access to the Landsat archive has already spurred scientific innovation and provided a foundation for REDD+ monitoring, reporting and verification.”

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.
