Quotes to Note
"By establishing baseline knowledge of Earth’s land areas throughout the last half-century, Landsat allows scientists to evaluate environmental change over time, to better understand the drivers and impacts of change, to model and predict future changes, and to chart these changes in the form of maps."
"The Landsat program—the longest-standing continuous global record of the Earth’s surface through satellite imagery—has enabled... solutions in support of people, planet, and prosperity since its launch in the 1970s."
"Landsat is a powerful example of the benefits of long-term investing to build robust data systems for sustained, longitudinal monitoring of environmental, social, and economic conditions."
“The first year we made Landsat open, we put out 25,000 Landsat scenes. Today, we put out millions of scenes a year.”
“Landsat provides a very good coverage of Amazonia both spatially and temporally.

“That’s the beauty of Landsat—it allows us to quantify these spatial patterns that are of high interest to water managers.”
"Another landmark program within USGS is called Landsat... USGS made a decision...to be able to open up that data, make it free, and the scientific discoveries, the articles, the access, the utility of that data just went absolutely through the roof. So it's been a really wonderful story about how opening up scientific data allows more discovery, gets people more excited... We really do try to put our data out there in a way that it is usable by the most amount of people as possible."
"It is a game changer for people who want to know the impact of a management action on particular piece of land, or how a dam affected the downstream area."
"The Landsat archive and other remote sensing systems provide the means to map and measure disturbance rates of the last 40 years."
