Quotes to Note
“It’s a fantastic time to be a user of satellite data, if you’re in that moderate resolution domain this is amazing. The Sentinels and Landsat together is going to be really a game changer. It truly is.”
"The fact that USGS and NASA makes this archive freely available, seems to me to be an inestimable service to the world, and the research community in particular."
"Sterling service of over four decades of Earth Observations. No ifs, no buts, just a long-term mission to aid science & society."
“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.”
“The data policy for Landsat was a paradigm shift for the world. There is no doubt about it.”
“Anything that’s historic, it’s got to be Landsat. In temporal depth, Landsat is really the only game in town.”
“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.”
“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.”
“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.”
"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."
“When you have Landsat you can actually show people how we are changing the face of the planet.”
