“Without the free and open Landsat data policy, a lot of commercial applications wouldn’t be feasible and a lot of commercial companies—including GDA—would be very different than they are.”


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


“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.”


“I really believe that Landsat data made a change in how we perceive global change. All of the things we have done so far would not have been possible without the unique Landsat dataset”


“From now on, we’re going to be able to track all of the different types of changes in glaciers – there’s so much science to extract from the data.”


“The relatively high spatial detail from Landsat allows differentiation of water use by crop type and individual farm field. At the moment, only Landsat can provide a consistent historical data going back to the 1980s that is long enough for trend analysis and investigate the relationships between management decisions and climatic drivers.”


“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.”


“We are now beginning to see that the combination of high performance computing, data storage facilities, data preparation techniques, and advanced systems can materially accelerate the value of Landsat data.”


“The availability and accessibility of remotely sensed digital imagery obtained from Landsat satellites allow coastal scientist—and more importantly community members—the opportunity to map, evaluate and continuously monitor shoreline movement at regular intervals given the unprecedented pace of Arctic climate change.”


“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.”


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


“I’d go to meetings and people were just jumping up and down because they had discovered another use for the data.”


“Satellite data is revolutionizing the way we map the world and the way we understand the natural and anthropogenic processes acting on Earth.”


“Landsat 9 replaces the older Landsat 7 and represents a step up in terms of image quality and data volume. Having two state-of-the-art platforms in orbit means more frequent data with excellent image quality.”


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


“The Landsat collection 1 datasets represent a milestone in remote sensing science, with comparatively stable radiometric calibration and atmospheric correction.”


“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.”


“Over the years, we’ve used the Landsat imagery to develop an incredibly accurate depiction of Earth and its changes over time, which we’ve published in Google Earth and Maps for use by billions of people worldwide.”


“Tropical deforestation plays a big role in global climate cycles… without the transparency of Landsat satellite data is difficult to put your finger on changing trends.”


“You may have heard me say this before, but I firmly believe there are few topics more fundamental to study than the workings of our planet. The earth sciences aim to unravel how the lithosphere, atmosphere, hydrosphere, and biosphere operate—and how they operate together. It is a science of synthesis. And it’s one that needs to move forward, both because of the great service the earth sciences perform for society and the understanding of world-shaping processes that they advance.”


“Landsat 8, which launched into orbit in 2013, is the newest sensor in the USGS/NASA Landsat Program — superior to its predecessors in many ways. Landsat 8 captures images with greater detail, truer colors, and at an unprecedented frequency — capturing twice as many images as Landsat 7 does every day.”


“I don’t think there’s any question about how important and how valuable MSS is.”


“Whether it’s since 1985 or 2000, we see this greening of the Arctic evident in the Landsat record.”


“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.”

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.
