“Satellite imagery can be used retrospectively, meaning that the data collected by satellites today will probably help solve issues we are not currently even aware of—an advantage which is invaluable.”

“The use of [Landsat] satellite imagery provides the means to monitor the agricultural water consumption over every square foot of land surface.”

“Usage rocketed in 2008, when Landsat made its images free. More than a million images were downloaded in the first year, compared with a previous annual high of 25,000 images sold. More than 20 million images have been downloaded since the archive opened and the rate continues to increase.”

“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.”

“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.”

“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.”

“In the world of water resource management, Landsat has played a key role in providing objective and continuous data for the United States, particularly in the arid west. Water-related benefits of Landsat imagery are also reaped far beyond the United States’ borders in countries such as Chile, Australia, Morocco, Sudan, and Venezuela, which are using Landsat data to make informed decisions regarding natural resource allocation and use.”

“…Landsat products can be used—and are necessary—for quantifying and summarizing water use volumes at spatial scales that are relevant for water resource studies in water-limited regions.”
