Eyes on Earth Episode 135 – Exotic Annual Grasses and Sheep Grazing
Exotic annual grasses, or EAGs, are invasive species. They outcompete native grasses. They are extremely flammable. And they are expanding into higher elevations. Targeted sheep grazing is one way to combat these invasive grasses, manage fire risk, and help restore native sagebrush in western states.

Eyes on Earth Episode 136 – The EROS Test Site
Landsat has been accurate and reliable for over 50 years because of the diligent calibration and validation work done by the team at EROS. One of the ways the team validates what they have so carefully calibrated is to take measurements on the ground while Landsat passes by overhead.

Eyes on Earth Episode 131 – Using AI in Geospatial Work
Eyes on Earth tackles artificial intelligence (AI) in a 2-part episode. AI is quickly becoming a necessary part of geospatial work at EROS, helping us efficiently do science to better manage our world. In Part 1, EROS Director Pete Doucette discusses AI and its current and upcoming impact on our work at EROS.
