In this USGS video, Alan Belward from the European Union’s Joint Research Center discusses how Landsat helps his team promote sustainable development.
Some quotes to note:
“Landsat… is everywhere and has been for 40 years.”
“It’s being ability to go back in time for the same location, with the same program, that’s given us a tremendous amount of really valuable information… With Landsat we can do that because the archive is so rich.”
“When you have Landsat you can actually show people how we are changing the face of the planet.”
