Landsat Next Defined

Landsat Next Defined

Landsat Next is on the horizon—the new mission will not only ensure continuity of the longest space-based record of Earth’s land surface, it will fundamentally transform the breadth and depth of actionable information freely available to end users. Take a look at the new capabilities that will define the next Landsat mission.

Data as Good as it Gets:
A Discussion with Brian Markham

Why do we calibrate Landsat data? We spoke with Brian Markham, a key figure of Landsat calibration science for four decades. He said that it all comes down to this: “If we’re using a system to quantify changes on the Earth, we must make sure the system we’re using is not changing.”

“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.”


“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”


“I don’t think people appreciate just how revolutionary it was when the Landsat archive became available for free and really empowered researchers and advocates to have access to that data at an affordable price to be able to do the kind of mapping that’s now been done, making visible what was previously invisible…”


“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.”


“We show governments across the world that it makes financial sense to release broadly and openly the data that the taxpayer has already paid for. It will build your economy, it is certainly good for transparent government and, it is a boon for capacity building and education.”


“The power of Landsat is that you can travel through time and you can travel through space and tell these really rich stories to help the greater good.”


“While Landsat instruments are fundamentally just electro-optical transducers that ingest photons and eject a digital bit stream, this transduction relies upon the state of the art in numerous technologies including optics, precision electromechanics, detectors, advanced materials, cryogenics, and signal processing.”


“[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.”


“Landsat 8 is an incredible resource for global change research and has been used in a diverse array of scientific endeavors including the monitoring of deforestation, population growth, and glacier recession.”


“We have so many options with Landsat Next, to add additional information and context to support our wetland managers as well as continuing the historical record of change and variability of our wetlands.”


“The primary archive available for reviewing the positions of coastlines and effects of sea-level rise is Landsat.”


“As one of the longest data archives suitable for this purpose, Landsat data allows us to analyze coastal wetland change over time-periods that enable us to monitor long-term directional change in the extent of the world’s coastal ecosystems and distinguish them from natural fluctuations. Our work on tidal flats and global coastal wetland change would not be possible without free access to a long-term, spatially comprehensive dataset such as Landsat.”


“While Landsat instruments are fundamentally just electro-optical transducers that ingest photons and eject a digital bit stream, this transduction relies upon the state of the art in numerous technologies including optics, precision electromechanics, detectors, advanced materials, cryogenics, and signal processing.”


“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.”


“There should be no competition between satellite remote sensing and fieldwork, there should only be collaborations.”


“Landsat provides a very good coverage of Amazonia both spatially and temporally. We have known for some time already that the Landsat images can be used to identify ecologically relevant environmental and biotic variation in Amazonian rainforests, but this is the first time we use satellite images to actually predict species distributions.”


“By using Landsat 8 imagery, and classification tree analysis, which is an advanced artificial intelligence routine, we have been able to construct a reliable classification system to identify cheatgrass infestations that is accurate. This has implications for fire susceptibility. Cheatgrass is driving wildfire on rangelands and we need to identify areas that have heightened susceptibility to wildfire.”


“Landsat’s work is epic in scale. In 43 years, it has amassed over a petabyte of data, with over 4 million scenes and counting.”


“Those are the Islands of the Four Mountains… The Landsat image shows them on June 8, 2013… One of the things I love about science is how it gives us perspective.”


“We knew that ice had been retreating from this region recently but now, thanks to a wealth of freely available satellite data, we know this has been occurring pervasively along the coastline for almost half a century.”


“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.”


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


“Satellites like those in the the Landsat program – which celebrates its 50th anniversary on July 23, 2022 – have become crucial for pinpointing urban risks so cities can prepare for and respond to extreme heat, a top weather-related killer.”

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.
