“Landsat satellite data are the most important source we have about how much deforestation happens each year across the Amazon.”


“The USGS’ incredible gift of open-source [Landsat] imagery and this kind of tool are truly advancing what non-scientists can expect when it comes to views of their planet. Never before have regular people had such ready access to geographic data at this depth and quality.”


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


“The Landsat program provides an unparalleled historical record of coastal observations that captures how the world’s coastlines have changed over time in incredible detail.”


“A 35-year dataset in marine biology is really hard to find… But we need long-term data to understand climate change and how it impacts populations. This was an exponential increase in the amount of information available about kelp forests in Oregon.”


“We knew that ice had been retreating from this region recently but now, thanks to a wealth of freely available satellite data, we know this has been occurring pervasively along the coastline for almost half a century.”


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


“Landsat is providing better [surface] water data—not just at the state level or nationally, but globally”


“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…”


“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.”


“[T]he pivotal aspect of the Landsat mission is the acquisition and curation of the most comprehensive and longest uninterrupted cross-calibrated EO data record ever gathered, with ensured continuity, and with ongoing efforts to consistently reprocess the entire image archive to incorporate cutting-edge advances in data preprocessing, which are then distributed as ‘collections’.”


“We recognize the essential role forests play in the long-term health of our planet, in contributing to sustainable development, and in meeting our shared goal of avoiding dangerous climate change. More than a billion people depend directly on forests for their livelihoods, and the remaining six billion of us depend on forests for a variety of economic, social, and environmental benefits such as the rainfall, biodiversity, pollinators, carbon storage, and clean water they provide. Forests a…


“Dai Yamazaki, a hydrodynamic engineer at the Japan Agency for Marine-Earth Science and Technology, calls the new [Landsat-based] imagery collection the best understanding yet of Earth’s changing surface water.”


“A 35-year dataset in marine biology is really hard to find… But we need long-term data to understand climate change and how it impacts populations. This was an exponential increase in the amount of information available about kelp forests in Oregon.”


“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.”


“For our main aim of quantifying surface water extent dynamics during a period of high hydro-climatic variability, Landsat was the only satellite archive to meet all our criteria.”


“I don’t think there’s any question about how important and how valuable MSS is.”


“Landsat has been producing Big Data since before data was big.”


“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.”


“Thanks to Landsat, we were able to dramatically improve our satellite base map in Google Earth and Google Maps on two separate occasions, first in 2013, and again in June 2016. Our most recent 15 meter-per-pixel global mosaic was made from over 1.5 million Landsat 7 and Landsat 8 images and forms the view of Earth you see across our mapping products for the first twelve zoom levels of the imagery basemap.”


“Tropical deforestation plays a big role in global climate cycles… without the transparency of Landsat satellite data is difficult to put your finger on changing trends.”


“Landsat is the crown jewel of Earth Observation datasets—unique 40+ year archive.”

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.
