“The advent of Landsat data enabled an unparalleled increase in our understanding of the Earth system.”


“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.”


“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…


“[Landsat] became freely available in 2008 and I think that that completely changed how we are able to use this type of data for decision making.”


“The Landsat time series is so convenient and easy to use and has triggered science that was not possible a few decades ago.”


“The primary archive available for reviewing the positions of coastlines and effects of sea-level rise is Landsat.”


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


“Landsat pays dividends not only to the prosperity of the global economy, but also to people and planet.”


“We looked at satellite images taken by the NASA-U.S. Geological Survey Landsat missions from 1972 and 1999 and the loss of forest and woodland cover along valleys and steep slopes was clear: eighty percent of the forests were gone. Through our analysis of Landsat forest change maps using GIS, we also calculated that the risk of landslide had increased fivefold during that time.”


“Landsat’s work is epic in scale. In 43 years, it has amassed over a petabyte of data, with over 4 million scenes and counting.”


“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.”


“The success of a mission, and the societal benefits it creates, relies on many factors, including design, manufacture, launch, and operation of the sensor. However, it also includes data acquisition, accessibility, availability, and continuity, all of which are embodied by the Landsat program.”


“The economic value of just one year of Landsat data far exceeds the multi-year total cost of building, launching, and managing Landsat satellites and sensors.”


“Data from Landsat and the MODIS sensor are well-suited to help people make informed policy decisions about ecosystem health, water management, agriculture and much more.”


“Satellite imagery can be used retrospectively, meaning that the data collected by satellites today will probably help solve issues we are not currently even aware of—an advantage which is invaluable.”


“To make accurate machine learning models of major crops, we needed decades of satellite imagery from the entire globe. Thanks to Google Earth Engine hosting the entire Landsat archive publicly on Google Cloud, we can focus on algorithms instead of worrying about collecting petabytes of data. Earth observation will continue to improve with every new satellite launch and so will our ability to forecast global food supply.”


“By analyzing 34 years of [Landsat] data, we estimated that about 56% of the rivers globally are affected by seasonal ice [and] that there is 2.5 percentage points decline of river ice globally during this time.”


“You can see the changes of your orchard over time & over space, and by measuring the canopy temperature [with Landsat] you can see whether the canopy is in balance with the rest of the environment around the trees.”


“With the Landsat satellite system capable of delivering global coverage every 8 days, we have an unprecedented ability to monitor global forest change. The 2014 tree cover loss data, incorporating hundreds of thousands of Landsat images, confirms that deforestation is not just high in certain countries, it’s speeding up. The next step is to use this information to improve forest protection and more equitably balance economic development with the invaluable ecosystem services forests provid…


“We cannot do this project if the Landsat program doesn’t deliver this open data to the scientific community… We are benefiting from these long-term investments now.”


“Until recently the National Geospatial-Intelligence Agency has relied on very high spatial resolution imagery to assess environmental conditions that may pose threats to national security. This project has demonstrated the beneficial use of Landsat to assess water quality at a regional scale, which enables a broader understanding of changing environmental conditions.”


“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.”

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.
