“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.”

“The data policy for Landsat was a paradigm shift for the world. There is no doubt about it.”

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

“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.”

“The long, consistent view of Earth from space provided by Landsat sparks advances in science, enables more efficient natural resources management, and promotes profitable applications of the data in commerce and industry. In step with the National Research Council and other objective reviews, the non-federal Landsat Advisory Group has found that the broad benefits of Landsat far outweigh the cost.”

“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.”

“Landsat sees the earth in a unique way. It takes images of every location in the world to reveal earth’s secrets, from volcanic activity to urban sprawl.”

“With these new [Landsat] data, we can begin to unravel the mechanisms by which the ice flow is speeding up or slowing down in response to changing environmental conditions.”

“Landsat 9 data will be delivered in a format that is consistent with currently available data from the previous Landsat satellites. This provides an unbroken story of land changes through over 40 years of Earth observation data.”

“It’s really a new era for Landsat, in that we’re going to have two observatories with very similar capabilities and very similar—if not identical—performances operating together. And this is going to provide more data to the Landsat mission than we’ve ever had before.”

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

“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.”

“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.”

“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…”

“Until we made the map of coral reefs with Landsat 7, global maps of reefs had not improved a lot since the amazing maps that Darwin drafted.”

“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.”

“[Landsat] became freely available in 2008 and I think that that completely changed how we are able to use this type of data for decision making.”

“Many of our customers’ work couldn’t be done without Landsat.”

“Landsat 8 represents yet another substantial advance to continuing a 40 year land data record, essential to understanding the Earth’s biosphere, anthropogenic changes to land use and land cover, the terrestrial carbon cycle, and the consequences for climate and biodiversity. This important extension to the Landsat series, the Landsat 8 mission, was achieved, through an outstanding interagency and industrial partnership, effectively managed to achieve breakthrough improvements in satellite …

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

“There is a sensor in the Landsat satellite which measures the intensity of the reflected radiation back into space. What if we could use satellite imagery from the Landsat program to find fossils?”

“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.
