Quotes to Note
"Land cover is fundamental for a plethora of applications. Approaches using #Landsat time series have been transformative."
“Thanks to satellites and to science, we now know much more about Earth than we did on the first Earth Day fifty years ago.”
“I don’t think there’s any question about how important and how valuable MSS is.”
"Because Landsat's been operating for so long—thermal imaging has been enabled since the 1980s—we can study how patterns in water use have changed over the landscape over long periods of time as the climate has changed and as land use patterns have changed. So Landsat has been really a critical sensor for our work."
“The archive is just going to continue to yield good information, good science, better management, reduced costs... The biggest contribution of Landsat will be that archive.”
“You can launch a new satellite, but you can’t put something up in the past. Landsat will always be that historic record that new satellites can tie themselves to.”
"@USGSLandsat @NASA_Landsat wrote the book on open data, how to do it right, how it creates businesses and benefits economy, and — of course — gifts the world with a 4+ decade *scientific* record of our planet's changing dynamics."
“A 35-year dataset in marine biology is really hard to find... But we need long-term data to understand climate change and how it impacts populations. This was an exponential increase in the amount of information available about kelp forests in Oregon.”
"Using Landsat images, an epidemiologist can build dynamic prediction models that take into account sudden environmental changes which may increase the risk of disease spread."
“By analyzing 34 years of [Landsat] data, we estimated that about 56% of the rivers globally are affected by seasonal ice [and] that there is 2.5 percentage points decline of river ice globally during this time.”

"The results of the Scopus bibliometric analysis indicate that inland water quality remote sensing has been growing dramatically since its introduction in the 1970s...The most pronounced year-on-year jump occurs right after 2008, which corresponds to the public release of freely available Landsat imagery by NASA and the US Geological Survey...This result is consistent with previous research showing that for multiple earth observation fields, the release of the Landsat archive resulted in more frequent and larger-scale studies."
