“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.”

“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.”

“We would not have been able to complete this research without Landsat’s free and open data policy.”

“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.”

“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.”

“The value of Landsat data is internationally recognized as indispensable to science, natural resource management, commerce, security, foreign policy, agriculture, and education.”

“With the full Landsat record available, we can finally look at really big problems, like the global carbon cycle.”

“A recent industry report estimates that total annual value of $2.19 billion, far exceeding the multi-year total cost of building, launching, and managing Landsat satellites and sensors. The value is derived from consumer use of the data. There is no inherent value in idle data.”

“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.”

“An alert system operating at the scale presented here depends on systematic global acquisitions, robust preprocessing, and free and accessible data. Only Landsat has these criteria at medium spatial resolutions, with Sentinel aspiring to emulate Landsat.”

“The Landsat mission has been monitoring Earth from orbit for more than 40 years. It is by far the longest continuous record of the surface of the planet, and certainly one of the most valuable data sets in existence.”

“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.”

“With 32 years’ worth of data — and ongoing data collection — the Landsat data record (satellites 5, 7 and 8) captures the decadal and interannual variability in forest losses and gains needed to drive global carbon cycle models.”

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

“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.”

“The Landsat satellites have also proved to be very useful, particularly for trying to do more detailed, finer-scale risk mapping.”

“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.”

“Even though I have a book coming out about the Moon Landing, I’ll say it: Landsat is likely the greatest, most impactful, yet under-appreciated, accomplishment of the entire space age.”

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

“That is one cool thing about Landsat… people are always finding new applications.”

“The [Landsat-informed] World Settlement Footprint is a great example on how we can mobilize the data revolution for the benefits of all countries and cities, leaving no one behind, which is one of the leitmotifs of the 2030 agenda on sustainable development.”

“The Landsat Program continues to be one of the most valuable, respected, and referenced Earth observation programs in the world.”

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.
