“That’s the beauty of Landsat—it allows us to quantify these spatial patterns that are of high interest to water managers.”

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

“The USGS’ incredible gift of open-source [Landsat] imagery and this kind of tool are truly advancing what non-scientists can expect when it comes to views of their planet. Never before have regular people had such ready access to geographic data at this depth and quality.”

“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.”

“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.”

“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.”

“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.”

“In the world of water resource management, Landsat has played a key role in providing objective and continuous data for the United States, particularly in the arid west. Water-related benefits of Landsat imagery are also reaped far beyond the United States’ borders in countries such as Chile, Australia, Morocco, Sudan, and Venezuela, which are using Landsat data to make informed decisions regarding natural resource allocation and use.”

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

“Landsat is an invaluable tool for people working in our field of community wildfire safety.”

“What should be done with the old bird?”

“Because of Landsat’s global purview and long history, it has become a reference point for all Earth observation work and is considered the gold standard of natural resource satellite imagery.”

“The fact that USGS and NASA makes this archive freely available, seems to me to be an inestimable service to the world, and the research community in particular.”

“Fire perimeters collected using Landsat imagery are accurate, timely and cost-effective.”

“[T]he pivotal aspect of the Landsat mission is the acquisition and curation of the most comprehensive and longest uninterrupted cross-calibrated EO data record ever gathered, with ensured continuity, and with ongoing efforts to consistently reprocess the entire image archive to incorporate cutting-edge advances in data preprocessing, which are then distributed as ‘collections’.”

“The really unique part about the Landsat record is the fact that it goes back to the ’70s. I can’t imagine what it would be like to describe what this volcano did without having a timeseries of Landsat. 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.”

“What a Landsat it is! The data are strikingly good and the delivery system is flawless. Landsat 8 arrives just as Landsat data use has exploded under the free data policy and the ability to deliver geolocated and atmospherically-corrected products… new and exciting applications are being revealed daily.”

“The Landsat archive enables us to develop products that tackle problems and address issues at a continental scale. For a country the size of Australia, this would simply not be possible without free and open access to the full time-series that the Landsat archive provides.”

“Landsat and SRTM are my eyes on the ground. Without them I am totally blind. They are great gifts to humanity.”

“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.”

“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 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.
