"If you don't do the calibration right, you can't do anything else."

"Landsat data is hugely important for society, science, and technology."

"We started with all of the Landsat images from the beginning of the [30-meter resolution era of the] Landsat program, so we could go back to 1984 and show how the surface of the planet had changed. It shows the changes in cities, the birth of cities. It shows flooding. It shows things like deforestation. It shows the incredible expansion of agriculture. There's just so many things you get from that data set."

— Randy Sargent, senior systems scientist with the CREATE Lab, "Savvy Use of Data, Technology Tells the Planet's Story;" Carnegie Mellon University News, Jan 18, 2019

"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."

“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.”

— Luba Reshitnyk, Hakai geographer, "Mapping Kelp from Space," Hakai Institute, Dec 6, 2018

“I saw more use of Landsat as the gold standard of calibration than I’ve ever seen in the past. Most of the commercial vendors I heard from called out Landsat as the gold standard. Even the European vendors called out Landsat, which I thought was unique."

— Greg Stensaas, manager of the Requirements, Capabilities and Analysis for Earth Observation (RCA-EO) project and JACIE coordinator for EROS, EROS Headlines, Oct 5, 2018

"Landsat pays dividends not only to the prosperity of the global economy, but also to people and planet."

— Jay Neuner, GEO Observations Blog, Oct 4, 2018

"Landsat is proof-positive of the value of Earth observation data, and particularly open access to Earth observation data."

— Jay Neuner, GEO Observations Blog, Oct 3, 2018

"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."

— Josef Aschbacher, Director of EO Programs, European Space Agency, Geospatial World, Oct 3, 2018

"I don’t think people appreciate just how revolutionary it was when the Landsat archive became available for free and really empowered researchers and advocates to have access to that data at an affordable price to be able to do the kind of mapping that's now been done, making visible what was previously invisible…”

— Frances Seymour, senior fellow at the Center for Global Development, Twitter interview by Kate Fickas at 2018 ForestSAT meeting, Oct 2, 2018

"By establishing baseline knowledge of Earth’s land areas throughout the last half-century, Landsat allows scientists to evaluate environmental change over time, to better understand the drivers and impacts of change, to model and predict future changes, and to chart these changes in the form of maps."

— Jessica Espey, Thematic Research Network on Data and Statistics (TReNDS) Director, Sustainable Development Solutions Network (SDSN)/TReNDS Case Study of Landsat, Sep 27, 2018
