“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.”


“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.”


“Landsat has been extremely beneficial as it allowed us to frequently evaluate the movement of the shoreline based on data gleaned from one consistent source over the duration of the study period. Further, the continued use of Landsat will allow for ongoing monitoring of the coastline in this region to ensure that potential infrastructural improvements are sustainable based on projections of near-term climate change.”


“Landsat 8 global ice mapping is enabled by its better data acquisition rate.”


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


“Landsat offers a globally consistent data set with a short enough revisit time to allow us to consider the percent of time that surface water is present on an annual and seasonal basis, while its 30 meter resolution also enables detection of smaller ponds and rivers, providing greater connectivity.”


“You may have heard me say this before, but I firmly believe there are few topics more fundamental to study than the workings of our planet. The earth sciences aim to unravel how the lithosphere, atmosphere, hydrosphere, and biosphere operate—and how they operate together. It is a science of synthesis. And it’s one that needs to move forward, both because of the great service the earth sciences perform for society and the understanding of world-shaping processes that they advance.”


“Sentinel-2a is essentially Europe’s version of the American Landsat mission.”


“It’s a treasure trove.”


“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.”


“With applied conservation programs, we’re using that [Landsat] imagery to say here are the areas that we can prioritize for conservation management, and here are areas that maybe we can let go. It’s a very powerful tool for getting conservation to happen.”


“The Landsat time series is so convenient and easy to use and has triggered science that was not possible a few decades ago.”


“Satellite data is revolutionizing the way we map the world and the way we understand the natural and anthropogenic processes acting on Earth.”


“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.”


“It is undeniable that having access to long-term satellite data has allowed ecologists and environmental managers to increase their understanding of the natural world, to make predictions about how this world might transform and to design efficient mitigation and adaptation strategies in the face of global environmental change.”


“Thanks to its detailed spatial resolution, Landsat made the estimation of small reservoirs’ surface area possible.”


“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.”


“From a valuation standpoint, Landsat is an extremely valuable public good just in its direct use—let alone the economic value of all the indirect uses built on the direct data.”


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


“Our new interface specifically uses Landsat to track flow velocity fields of Greenland’s outlet glaciers and how they have changed over time.”


“Giant kelp forests are especially sensitive to environmental changes and have a history of undergoing abrupt, dramatic declines and increases in response to a variety of climatic and human-induced factors. The application of our remote sensing methods to the long-term (continuous since 1984), high frequency (~ once per month) global coverage of Landsat imagery is providing a unique opportunity for studying these dynamics over spatial and temporal scales that were previously impossible to e…


“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.”


“During the decade following 1969, a singular development catapulted computer mapping: the launch of Landsat by NASA and the U.S. Department of the Interior in July 1972.”


“It’s a fantastic time to be a user of satellite data, if you’re in that moderate resolution domain this is amazing. The Sentinels and Landsat together is going to be really a game changer. It truly is.”

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.
