Visualizing Data—Landsat at the World Economic Forum

The World Economic Forum has published a talk given by Illah Nourbakhsh, professor of robotics from Carnegie Mellon and Matthew Hansen, a remote sensing specialist at the University of Maryland, that demonstrates how visualizing big data can revolutionize the way we understand and imagine the world.
Landsat data features prominently into this talk (see timestamps 06:10 and 07:00–16:02). In this presentation, Matt Hansen commented:

“Very importantlty, big data and its use for societal good is based on really progressive data policies. The Landsat sensor has 40 years of data in the archive and it is available to anyone on the planet.”

“One of the things we like about the [Landsat] satellite is that as it orbits the Earth it is calibrated consistently so we have a globally constant picture that we can make comparisons—apples to apples—of what’s happening. We can drill down to countries, even parks, and say this is what is happening at a local scale. That is another really powerful part of this big data story.”
