"Landsat is indispensable for Timelapse in Google Earth—and so much more. Thank you @USGSLandsat @NASA_Landsat program, the world’s only long-term, continuous, data record of the entire Earth’s land surfaces dating back to 1972."

"Landsat provides an unparalleled record of how terrestrial Earth has changed since the early 1970s, closely coinciding with the beginning of rapid environmental change. It provides important historical context for the current state of land cover and land use and provides a reference for identifying abnormal types and rates of change."

"I’m grateful that NASA, USGS, and scientists like William Pecora had the foresight to begin collecting Earth observations a half century ago."

"The first step of ecosystem accounting is to actually map the dynamics of ecosystems over time."

"I do sleep, but I dream of Landsat!" 

"Without Landsat, we’d still be in the Dark Ages of tracking global forest carbon using spreadsheet models."

"The Landsat Program continues to be one of the most valuable, respected, and referenced Earth observation programs in the world."

"That is one cool thing about Landsat... people are always finding new applications."

"[Landsat] became freely available in 2008 and I think that that completely changed how we are able to use this type of data for decision making."

"This global census can help identify other lakes in need of monitoring or remediation, Dr. Shugar said. 'We hope that it allows governments to see where the hot spots might be for glacial lakes growing in the future.'"

"Whether it’s since 1985 or 2000, we see this greening of the Arctic evident in the Landsat record."

"LANDFIRE is the only complete, nationally consistent collection of spatial resource datasets with an ecological foundation."
