Quotes to Note

 

“The community was very vocal regarding the value of a free and open data policy.”

— Frank Avila, National Geospatial-Intelligence Agency and National Geospatial Advisory Committee member, Keep Landsat data free, panel urges Department of the Interior; Science Magazine, Jun 12, 2019

“You can see the changes of your orchard over time & over space, and by measuring the canopy temperature [with Landsat] you can see whether the canopy is in balance with the rest of the environment around the trees.”

— Dr. Daniele Zaccaria, UC Davis, "The food grown to withstand disaster", BBC's Follow the Food, Jun 6, 2019

“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.”

— Kristine Engemann, Department of Bioscience at Aarhus University in Denmark, Green Space is Good for Mental Health, Landsat Helps Establish, May 22, 2019

"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."

— Hesham El-Askary, Center of Excellence in Earth Systems Modeling & Observations and Schmid College of Science and Technology, Chapman University, The Curious Case of Missing Mangroves in the Jubail Conservation, May 9, 2019

"Global Forest Watch’s ability to take advantage of Landsat imagery to produce a global forest monitoring platform highlights why remote sensing has become such a revolutionary technology. The imagery has achieved a state-of-the-art quality—NASA’s Landsat data is delivered in 30x30meter squares and has been for the past 40 years. Beyond this, it has been made radically accessible. Since 2008, anyone has been able to view and download the data from the United States Geological Survey (USGS) website free of charge, which has made satellite imagery a primary tool for forest and land cover monitoring. Without it, GFW would not be possible."

— Sarah Ruiz, writer/editor at Global Forest Watch, To Learn about the Earth, the Best Vantage Point is in Space; Global Forest Watch blog, Apr 11, 2019

"Landsat, now one of the largest and most powerful tranches of Earth-science data, is an invaluable scientific resource."

"Without the free and open Landsat data policy, a lot of commercial applications wouldn’t be feasible and a lot of commercial companies—including GDA—would be very different than they are."

— Dmitry L. Varlyguin, Geospatial Data Analysis Corp. Vice President & Chief Scientist, How Looking for Clouds Helped Forecast Global Food Production, Apr 9, 2019

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

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

— Zhe Zhu, Assistant Professor of Natural Resources and the Environment at UConn & 2018-2023 Landsat Science Team member, "A Policy Proposal That Could Curb Remote Sensing Research" UConn Today, Mar 8, 2019

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

— Zeke Lunder, a pyrogeographer and founder of Deer Creek GIS, The Synoptic View of California’s Camp Fire: A Scorching Reality of Today’s Fires, Feb 19, 2019

"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."
