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


“Landsat has been extremely beneficial as it allowed us to frequently evaluate the movement of the shoreline based on data gleaned from one consistent source over the duration of the study period. Further, the continued use of Landsat will allow for ongoing monitoring of the coastline in this region to ensure that potential infrastructural improvements are sustainable based on projections of near-term climate change.”


“Landsat makes it possible to compare images over almost 5 decades and makes the role of climate change unmistakable in this incredibly beautiful mountainous part of Alaska.”


“We use Landsat images on a daily basis at SkyTruth for environmental monitoring.”


“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 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.”


“This [Google Earth] update was made possible in a large part thanks to the Landsat program and its commitment to free and accessible open data. Landsat, a joint program of the USGS and NASA, has observed the Earth continuously from 1972 to the present day and offers a wealth of information on the changes to the Earth’s surface over time.”


“It’s being able to go back in time for the same location, with the same program, that’s given us a tremendous amount of really valuable information… With Landsat we can do that because the archive is so rich.”


“Work has begun on the next mission, Landsat 9, with launch scheduled for late 2020. Plans for the next generation of Landsat are also underway, with a series of studies leading to a decision on the Landsat 10 and beyond architecture in 2018.”


“Landsat represents a public good, Earth-observation infrastructure that allows everyone to study their respective land resources and their change over time.”


“When I arrived in Gombe 50-plus years ago, looking up at the stars, it never occurred to me that one day, we’d be relying on remote sensing—satellites circling the globe high above—to help unite communities of people and save Gombe’s chimpanzees. NASA—through its resources and data and funding—is helping us to apply the kinds of innovative solutions needed to address the complex problems people and chimpanzees face today.”


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


“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.”


“Landsat satellite data are the most important source we have about how much deforestation happens each year across the Amazon.”


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


“It is undeniable that having access to long-term satellite data has allowed ecologists and environmental managers to increase their understanding of the natural world, to make predictions about how this world might transform and to design efficient mitigation and adaptation strategies in the face of global environmental change.”


“Landsat 8 can collect more than 700 images per day—14 times as much as in the 1980s.”


“Our mapping techniques build on the historical Landsat record to provide highly needed information on regional scale and this helps in evaluating subtle changes in mangroves over a long period of time (trends) and to detect sudden changes due to natural catastrophes or dramatic anthropogenic impacts… [and] Thanks to the increased abundance of Landsat satellite images, it is becoming progressively easier to collect available images of mangrove habitats captured at low tide and high tide.”


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


“When I arrived in Gombe 50-plus years ago, looking up at the stars, it never occurred to me that one day, we’d be relying on remote sensing—satellites circling the globe high above—to help unite communities of people and save Gombe’s chimpanzees. NASA—through its resources and data and funding—is helping us to apply the kinds of innovative solutions needed to address the complex problems people and chimpanzees face today.”


“Landsat is providing better [surface] water data—not just at the state level or nationally, but globally”


Landsat satellite imagery is ideal for gauging vegetation cover shifts because it supplies spectral data for surface areas of about 90 square meters – fine enough to track changing spectral signal patterns across large study areas.


“Satellite technologies have led to one of the most productive periods in the history of cartography, comparable only to the golden age of mapmaking in the sixteenth and seventeenth centuries.”


“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.”

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.
