“As a researcher with a limited budget, using the Landsat data for free made this project possible. The global geographic range together with free availability ensures that our study could potentially be repeated in other countries.”


“Several satellite systems can now measure the surface urban heat island, but the Landsat program provides decades of continuous, comparable data in the detail necessary to examine variations within a city. That continuity helps scientists measure the impact of changes and track how development patterns change a neighborhood’s heat profile.”


“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.”


“Landsat is an invaluable tool for people working in our field of community wildfire safety.”


“The economic and scientific benefits to the United States of Landsat imagery far exceed the investment in the system.”


“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…


“I am a big fan of Landsat 8 satellite images as a resource when making maps.”


“Landsat is the oldest continually operated program of its kind: Its satellites have been capturing images of the Earth since the Nixon administration.”


“Landsat provides a global view of the the worlds alpine glaciers and enables us to track their retreat in ways that would be difficult without this important environmental time series.”


“In a world of scarce resources, there are distinct tradeoffs in costs and benefits of land use, and whether to conserve or convert forest to cropland. Map-based images are perhaps one of the most succinct means of helping policymakers digest complex ideas of social and economically driven environmental change.”


“Science and reliable data need to be at the heart of policy decisions around the globe if we are to tackle climate change and other serious environmental challenges facing our world. It is vital that we share the trusted data that comes from Earth observation so citizens, scientists, and political leaders everywhere can most effectively work together to meet these most difficult challenges.”


“Landsat 9 replaces the older Landsat 7 and represents a step up in terms of image quality and data volume. Having two state-of-the-art platforms in orbit means more frequent data with excellent image quality.”


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


“Data from Landsat and the MODIS sensor are well-suited to help people make informed policy decisions about ecosystem health, water management, agriculture and much more.”


“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 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.”


“As a researcher with a limited budget, using the Landsat data for free made this project possible. The global geographic range together with free availability ensures that our study could potentially be repeated in other countries.”


“The economic and scientific benefits to the United States of Landsat imagery far exceed the investment in the system.”


“Agricultural engineer Jean-Francois Pekel and colleagues have created a kind of virtual time machine, showing past changes in surface water and providing a baseline for charting the changing future of our watery world. To achieve this feat, Pekel and colleagues used more than 3 million Landsat images of Earth’s lakes, wetlands, and rivers taken between 1984 and 2015.”


“What we’re able to do now is track the flow of the world’s ice from pole to pole and on every continent.”


“Landsat is an invaluable resource for developing these high resolution maps. Without the Landsat imagery we would not have the spectral information needed to decompose urban landscapes into Local Climate Zone types. Hence the data is at the heart of the project and it is the most critical piece—without Landsat there is no project.”


“By unleashing the power of our vast and open data resources, the Climate Data Initiative helps spark private sector innovation and will leverage resources for those on the front lines who are dealing with climate change. We are pooling into one place data from across the federal government to make it more accessible to the public and we hope our efforts will inspire other countries to follow suit.”


“We need to drive towards building sustainable cities and human settlements, and this depends on how well we measure these areas and how well we can predict the growth in all these cities in the future. I believe Earth observation and geospatial technologies give us the tools needed in order for us to grow in this direction.”


“Last year the White House found that GPS, weather satellites, and Landsat are the three most critical types of Earth-orbiting assets for civil applications, because they’re used by many economic sectors and fields of research.”

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.
