In this USGS Landsat In Action video, John Schott, with the Rochester Institute of Technology, discusses using Landsat Data over the years and how its thermal data tracks temperature changes in water bodies.
A quote to note from John Schott on the importance of the Landsat archive:
“We’ve got this data of every field, of every country…. the archive is just going to continue to yield good information, good science, better management, reduced costs. It’s incredible.”
