Quotes to Note


“Landsat’s thermal data is critical for tracking water use in the western United States, where rainfall can be short in supply and managing water resources is critical to ensuring a sustainable supply for farmers, cities, and natural ecosystems.”

— Bruce Cook, NASA Landsat 9 deputy project scientist, New Landsat Infrared Instrument Ships from NASA, Aug 23, 2019

"What should be done with the old bird?"

— From USGS EROS article:, Science Team Tackles Question of Landsat 7’s Future, Aug 6, 2019

"[T]he case for open data is more than proven by Landsat and Copernicus. Many innovative applications using these datasets are the dividends that benefit the taxpayer."

"The Landsat collection 1 datasets represent a milestone in remote sensing science, with comparatively stable radiometric calibration and atmospheric correction."

— Bruce Cook, NASA Landsat 9 deputy project scientist, New Landsat Infrared Instrument Ships from NASA, Jul 1, 2019

“The Landsat archive enables us to develop products that tackle problems and address issues at a continental scale. For a country the size of Australia, this would simply not be possible without free and open access to the full time-series that the Landsat archive provides.”

— Dr. Stephen Sagar, Aquatic Remote Sensing Project Leader at Geoscience Australia, More than Naught: The Z of Where Land Meets Sea, Jun 27, 2019

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

— Tom Patterson, National Park Service cartographer, Updating and Enhancing Maps with Landsat 8, Avenza Systems blog, Jun 13, 2019

“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."
