“Until recently the National Geospatial-Intelligence Agency has relied on very high spatial resolution imagery to assess environmental conditions that may pose threats to national security. This project has demonstrated the beneficial use of Landsat to assess water quality at a regional scale, which enables a broader understanding of changing environmental conditions.”


“Earth Observation data acquired by the Landsat missions are of immense value to the global community and constitute the world’s longest continuous civilian Earth Observation program.”


“We’ve got this data of every field, of every country…. the archive is just going to continue to yield good information, good science, better management, reduce costs. It’s incredible.”


“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.”


“As the global population surpasses eight billion people, it will be important to effectively manage land to sustain life on Earth. Landsat 9 will pair with Landsat 8 to greatly improve our understanding of what is driving changes to our lands, surface waters, and coasts, and how we can sustainably manage it.”


“Without Landsat’s long record, studies like ours would be impossible to undertake, because we don’t have a time machine to go back to the 1970s and 1980s and see how Turkey’s glaciers were doing then. Using Landsat and commercial satellite data together, we can map glaciers with high accuracy. It’s a powerful combination for studying the Earth from space.”


“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.”


“We would not have been able to complete this research without Landsat’s free and open data policy.”


“Our Landsat-based insect atlas facilitates comparisons across space, time, and insect agents that have not been possible to date.”


“Having water consumption maps produced quickly on Smartphones has been everyone’s dream. In two years time we hope to see all farmers watching their fields from their phones and scheduling irrigations. EEEFlux is making Landsat the evapotranspiration satellite.”


“Global Forest Watch’s ability to take advantage of Landsat imagery to produce a global forest monitoring platform highlights why remote sensing has become such a revolutionary technology. The imagery has achieved a state-of-the-art quality—NASA’s Landsat data is delivered in 30x30meter squares and has been for the past 40 years. Beyond this, it has been made radically accessible. Since 2008, anyone has been able to view and download the data from the United States Geological Survey (USGS) websi…


“With Landsat we can see temperature of individual fields and how it varies from field-to-field. The temperature of the land surface gives us a good indication of how rapidly water is evaporating off that surface. And this is really important for knowing how healthy the crops are and also for supplying information for irrigators: how much water was used last week and how much do they need to replenish in the current week to keep the crops healthy.”


“Landsat is the longest civil satellite data collection we have. The USGS opening the archive has created opportunities for instructors like us to integrate students.”


“Landsat is really important because it gives us that time component. We can go back in time and see what an area let’s say a coastal zone or a mangrove forest has been like over time.”


“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.”


“We’re happy to see that the Agribotix imaging system performs so well when compared to Landsat 8, one of the highest quality land imaging satellite systems…”


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


“Our mapping techniques build on the historical Landsat record to provide highly needed information on regional scale and this helps in evaluating subtle changes in mangroves over a long period of time (trends) and to detect sudden changes due to natural catastrophes or dramatic anthropogenic impacts… [and] Thanks to the increased abundance of Landsat satellite images, it is becoming progressively easier to collect available images of mangrove habitats captured at low tide and high tide.”


“The economic value of just one year of Landsat data far exceeds the multi-year total cost of building, launching, and managing Landsat satellites and sensors.”


“This is an example of something government can do well: investing in infrastructure that broadly benefits society, and provides a stable platform for the development of businesses and economic activity. Landsat is the data equivalent of the interstate highway system, a public good that has spawned a thriving for-profit remote sensing industry in the US and beyond.”


“We have mapped then analyzed the area of forest converted each year to industrial oil palm and pulpwood plantations from 2001 to 2016, looking mainly at land under company management – that is, concessions. We use LANDSAT satellite imagery to monitor the annual expansion of plantations. We combine this information with annual maps of forest loss also derived using LANDSAT satellites by Matthew Hansen’s research group at the University of Maryland. The Hansen dataset, as we call it, produce…


“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 use Landsat 8 to document glacier velocity patterns on a mountain-range-wide scale. Mapping glacier velocity is facilitated by Landsat’s high radiometric resolution and precise geolocation.”

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.
