Quotes to Note

 

“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.”

— Martha Anderson, U.S. Department of Agriculture and Landsat Science Team member, Landsat In Action—Monitoring Crop Land with Martha Anderson, Feb 5, 2018

“The data policy for Landsat was a paradigm shift for the world. There is no doubt about it.”

— Barbara Ryan, Director of GEO, USGS Landsat in Action video, Jan 23, 2018

“Anything that’s historic, it’s got to be Landsat. In temporal depth, Landsat is really the only game in town.”

— Mike Wulder, Canadian Forest Service, on historical land use change, USGS Landsat in Action video, Jan 16, 2018

“We’ve got this data of every field, of every country…. the archive is just going to continue to yield good information, good science, better management, reduce costs. It’s incredible.”

— John Schott, Rochester Institute of Technology, on the Landsat archive, USGS Landsat in Action video, Jan 9, 2018

“It’s a fundamental resource for the Australian community. It’s used at local government level, state government level, and national levels. It’s our most important Earth-observing satellite with out a question in my mind.”

— Adam Lewis, Geoscience Australia’s Acting Chief Scientist, on the Australian archive of Landsat data, USGS Landsat in Action video, Jan 2, 2018

“The most unique thing about Landsat is its length of record… The ability to go back 30 years or more is something you just can’t do with any other sensor.”

— Andrew Elmore, University of Maryland Center for Environmental Science, USGS Landsat in Action video, Dec 14, 2017

"We have mapped then analyzed the area of forest converted each year to industrial oil palm and pulpwood plantations from 2001 to 2016, looking mainly at land under company management – that is, concessions. We use LANDSAT satellite imagery to monitor the annual expansion of plantations. We combine this information with annual maps of forest loss also derived using LANDSAT satellites by Matthew Hansen’s research group at the University of Maryland. The Hansen dataset, as we call it, produces very accurate tree loss maps over the humid tropics, and combined with a good forest mask, reveals where old-growth forests have been cleared...By combining our annual maps of plantations with this forest loss dataset, we can extract the area of forest converted each year to industrial plantations by producing companies. This is what we call company-driven deforestation."

"Landsat 8 is part of a revolution of how much remote sensing can do to track the polar areas."

— Ted Scambos, Lead Scientist at the National Snow & Ice Data Center, USGS Landsat in Action video, Oct 18, 2017

“When you have Landsat you can actually show people how we are changing the face of the planet.”

— Alan Belward, scientist at European Union’s Joint Research Center, Landsat In Action - Interview with Alan Belward, Oct 18, 2017

“It’s being able to go back in time for the same location, with the same program, that’s given us a tremendous amount of really valuable information... With Landsat we can do that because the archive is so rich.”

— Alan Belward, scientist at European Union’s Joint Research Center, Landsat In Action - Interview with Alan Belward, Oct 18, 2017

“Landsat is everywhere, and has been for 40 years.”

— Alan Belward, scientist at European Union’s Joint Research Center, Landsat In Action - Interview with Alan Belward, Oct 18, 2017

"Within Australia, Earth Observation is so commonly used across all levels of government, industry and society that the minimum economic impact of Earth Observation from space-borne sensors alone is approximately $5.3 billion each year [Australian $; ~4.15B US$]."

— Australian Earth Observation Community Coordinating Group, Australian Earth Observation Community Plan 2026, Oct 2, 2017
