“The availability of continuous data streams of high quality and free of charge satellite observations such as the Sentinels of the European Copernicus program and the Landsat missions, in combination with the emergence of automated methods for large data processing and data analytics, and the democratization of computing costs, offer unprecedented opportunities to efficiently monitor the changes and trends in urban development globally.”

“Those are the Islands of the Four Mountains… The Landsat image shows them on June 8, 2013… One of the things I love about science is how it gives us perspective.”

“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.”

“The Deltares Aqua Monitor is the first global-scale tool that shows at 30-m resolution where water is converted to land and vice versa. With assistance from Google Earth Engine, it analyzes satellite imagery from multiple Landsat missions, which observed Earth for more than three decades, on the fly.”

“Landsat 8 is an incredible resource for global change research and has been used in a diverse array of scientific endeavors including the monitoring of deforestation, population growth, and glacier recession.”

“The US satellite series—its current flier is named Landsat 8—pioneered the science of monitoring the planet from orbit. It has assembled a continuous record of the world’s fluctuating features that stretches back more than 40 years. In satellite terms, it is the gold standard.”

“Landsat has allowed managers to observe regional trends in kelp canopy area and biomass across more than 30 years. This is very valuable.”

“Sterling service of over four decades of Earth Observations. No ifs, no buts, just a long-term mission to aid science & society.”

“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.”

“The long time span covered by the Landsat scenes allows us to determine long-term flow velocity trends. The high temporal resolution lets us analyze seasonal flow velocity variations of numerous outlet glaciers…The monitoring system provides a powerful tool to examine the flow velocity pattern throughout time and space, and we have detected an acceleration pattern for a number of outlet glaciers.”

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

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

“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.”

“…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.”

“We recognize the essential role forests play in the long-term health of our planet, in contributing to sustainable development, and in meeting our shared goal of avoiding dangerous climate change. More than a billion people depend directly on forests for their livelihoods, and the remaining six billion of us depend on forests for a variety of economic, social, and environmental benefits such as the rainfall, biodiversity, pollinators, carbon storage, and clean water they provide. Forests a…

“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.”

“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.”

“We have mapped then analyzed the area of forest converted each year to industrial oil palm and pulpwood plantations from 2001 to 2016, looking mainly at land under company management – that is, concessions. We use LANDSAT satellite imagery to monitor the annual expansion of plantations. We combine this information with annual maps of forest loss also derived using LANDSAT satellites by Matthew Hansen’s research group at the University of Maryland. The Hansen dataset, as we call it, produce…

“The use of [Landsat] satellite imagery provides the means to monitor the agricultural water consumption over every square foot of land surface.”

“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.”

“Land cover is fundamental for a plethora of applications. Approaches using #Landsat time series have been transformative.”

“Landsat is history’s longest-running Earth imaging project. Its enormous data set cements it as an industry standard.”

“The USGS’s Landsat mission has an incredible 40-year record of the planet’s changing landscape, with virtually every spot imaged every eight days. It’s an incredible scientific asset.”

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.
