“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.”


“The Landsat satellite series has proven to be a perfect match to the needs of modern irrigated agriculture and water resources management.”


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


“What makes this [Landsat 8] mission team special is the fervor they brought to task. They were challenged to retain the historic data continuity, yet take advantage of new technology while balancing cost and complexity. Few, if any, missions face such a challenge with such consequences on the line. After more than a decade of dedication, this Team launched a new sensor that was more sensitive and robust than previous sensors, and provided not only data continuity but even more and better d…


“You can acquire data until the cows come home. But if the data isn’t available, you can only go so far. If people can’t rely on data availability and continuity, they won’t build a system to use it. And then the whole puzzle falls apart.”


“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.”


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


“[T]he case for open data is more than proven by Landsat and Copernicus. Many innovative applications using these datasets are the dividends that benefit the taxpayer.”


“We are in this unique position where we have ice core records from these mountaintops, and Landsat has these detailed images of the glaciers, and if we combine those two data sets, we see clearly what is happening.”


“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.”


“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.”


“This research was only possible thanks to the free and open Landsat data policy.”


“Landsat’s thermal data is critical for tracking water use in the western United States, where rainfall can be short in supply and managing water resources is critical to ensuring a sustainable supply for farmers, cities, and natural ecosystems.”


“NASA’s comprehensive study of Earth has provided much of the underlying understanding of current trends in the planet’s climate – including definitive measurements of rising sea levels, glacier retreat, ice sheet changes and the decline in the volume of the Arctic sea ice cap. Our satellites have provided global, long-term views of plant life on land and in the ocean. And our supercomputing power is allowing us to better understand how all the parts of the Earth system work together and he…


“Very importantly, big data and its use for societal good is based on really progressive data policies. The Landsat sensor has 40 years of data in the archive and it is available to anyone on the planet.”


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


“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?”


“Landsat data gives us a fuller picture of the planet we live on and the resources humanity needs to survive.”


“The first year we made Landsat open, we put out 25,000 Landsat scenes. Today, we put out millions of scenes a year.”


“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.”


“As the global population surpasses eight billion people, it will be important to effectively manage land to sustain life on Earth. Landsat 9 will pair with Landsat 8 to greatly improve our understanding of what is driving changes to our lands, surface waters, and coasts, and how we can sustainably manage it.”


“There is no other asset in the sky that can show us what Landsat does in terms of the effect of this eruption and also the effect of recovery following the eruption.”


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


“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.”

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.
