“The Landsat archive holds great potential for studying the processes behind the Greenland Ice Sheet’s response to our changing climate over multi-decadal time scales. It is essential that this record be exploited over other areas of the Greenland Ice Sheet.”

“Having all of this [30 m] Landsat data available more or less globally since 1984 will keep glaciologists busy for some more years, if not decades.”

“The key role of Landsat in the context of climate change is to document the impact of climate change on global ecosystems, which is highly relevant for the future availability of food, water, and fiber resources, as well as the provision of ecosystem services including biodiversity.”

“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 novelty of our study lies in the bigger picture—measuring glacier change over all main glaciated ranges in Bolivia—and in the identification of potentially dangerous lakes for the first time.”

“We have a globally consistent, locally relevant map product that can be used in a variety of applications: estimating emissions from deforestation, modeling biodiversity, assessing protected areas, and studying forest and human health. We plan to move our record forward and backward where Landsat has a sufficiently rich archive of data.”

“This portal harnesses more than 37,000 images from Landsat archives, dating back to the early 1970s, to track changes in outlet glaciers over time.”

“A growing archive of Landsat images allow us to see how quickly icesheets are changing.”

“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.”

“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.”

“The Landsat satellite series has proven to be a perfect match to the needs of modern irrigated agriculture and water resources management.”

“Landsat provides wide coverage of the Himalayas for years with spatial and spectral quality, especially now, with Landsat 8 that has enhanced spectral resolution, which enables the monitoring of glacier state.”

“Another landmark program within USGS is called Landsat… USGS made a decision…to be able to open up that data, make it free, and the scientific discoveries, the articles, the access, the utility of that data just went absolutely through the roof. So it’s been a really wonderful story about how opening up scientific data allows more discovery, gets people more excited… We really do try to put our data out there in a way that it is usable by the most amount of people as possible.”

“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.”

“We cannot replace Landsat with Copernicus. In fact the programs complement each other. The world has been benefitting from Landsat data for the past 40 years now. It is really a unique and extremely valuable data source that has provided knowledge and understanding of the planet.”

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

“We had to push the spatial resolution because we’re interested in humans.”

“Landsat 8 has been instrumental in monitoring smoke plumes as they spread across the Ninewa plains.”

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

“The majority of tropical countries are using Landsat imagery as the primary source of information to support their forest change assessments.”

“You need decades of data to say that a change in kelp is due to climate change rather than other cyclical factors, with Landsat, we have those data.”

“Landsat’s free and open data policy allows our coastline mapping methods to be easily scaled up and applied to other coastal regions, lowering barriers to understanding recent patterns and processes of coastal change globally.”

“Landsat, a joint program of the U.S. Geological Survey (USGS) and NASA, offers an unparalleled record of our changing planet, with satellites that have been observing the Earth since 1972 to the present day.”

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.
