“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.”

“The use of [Landsat] satellite imagery provides the means to monitor the agricultural water consumption over every square foot of land surface.”

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

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

“The tracking of over-irrigated areas for targeting irrigation advisory texts was completely dependent on Landsat TIR data.”

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

“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.”

“Without Landsat it would be essentially impossible to get good Ground Control Point locations from other sources.”

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

“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.”

“Landsat is proof-positive of the value of Earth observation data, and particularly open access to Earth observation data.”

“Having Landsat 9 in progress, and a long-term commitment to sustainable land imaging, is great for natural resource science and for data-driven industries such as precision agriculture and insurance.”

“The Landsat series of satellites is a cornerstone of our Earth observing capability. The world relies on Landsat data to detect and measure land cover/land use change, the health of ecosystems, and water availability.”

“Landsat is currently the only satellite program to provide a consistent, cross-calibrated set of records stretching back over more than four decades, which in turn means the program occupies a key position in the provision of terrestrial essential climate variables.”

“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.”

“When we showed historical Landsat and more recent high resolution images to communities and shared our analysis, people realized what they’d lost over time and wanted to engage in conversations about how to bring the forests back.”

“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.”

“@USGSLandsat @NASA_Landsat wrote the book on open data, how to do it right, how it creates businesses and benefits economy, and — of course — gifts the world with a 4+ decade *scientific* record of our planet’s changing dynamics.”

“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.”

“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.”

“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.”

“By analyzing velocity estimates extracted from 30 years of Landsat data, this study highlights the complex, and sometimes counterintuitive, interplay between surface meltwater and ice motion.”

“With the Landsat satellite system capable of delivering global coverage every 8 days, we have an unprecedented ability to monitor global forest change. The 2014 tree cover loss data, incorporating hundreds of thousands of Landsat images, confirms that deforestation is not just high in certain countries, it’s speeding up. The next step is to use this information to improve forest protection and more equitably balance economic development with the invaluable ecosystem services forests provid…

“When you have Landsat you can actually show people how we are changing the face of the planet.”

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.
