Eyes on Earth Episode 137 – Landsat Takes Yellowstone’s Temperature
The Yellowstone National Park area has more than 10,000 thermal features. And while Old Faithful is a pretty predictable geyser, some thermal features can change quite a bit. New ones can even pop…
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…
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…
Eyes on Earth Episode 134 – Data Accuracy: The Calibration and Validation of Landsat
Landsat is the longest-running, continuously operating record of Earth observations, and it’s the gold standard reference point that other civil and commercial satellite programs trust. If a…
Eyes on Earth Episode 133 – Vietnam War Bomb Craters
Declassified spy satellite imagery, distributed by the USGS EROS Center, is finding fascinating uses since being made available to the public starting in the 1990s. In this episode of Eyes on Earth,…
Eyes on Earth Episode 132 - Moving Forward with AI at EROS
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…
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…
Eyes on Earth Episode 130 – NLCD Accuracy
Every pixel has a story. At least that’s how land remote sensing scientist Jo Horton sees it. The new Annual National Land Cover Database (NLCD) was just released in October 2024. NLCD is widely used…
Eyes on Earth Episode 129 – What Happens During a Landsat Pass?
In this episode of Eyes on Earth, we talk to ground station technicians to find out how Landsat satellite data gets from the spacecraft to EROS and then to the archive. We see what it’s like in…
Eyes on Earth Episode 128 – 2024 EROS Fall Poster Session
In this episode of Eyes on Earth, we mingle at the 2024 EROS Fall Poster Session. A poster session is essentially a way for scientists to share their work with their colleagues in a public forum.…
Eyes on Earth Episode 127 – The Historic Landsat 7 Mission
In this episode of Eyes on Earth, we talk about the incredible career of Landsat 7, which collected science imagery of the Earth for nearly 25 years. The Flight Operations Team at NASA Goddard Space…
Eyes on Earth Episode 126 – Annual NLCD
In this episode of Eyes on Earth, we talk about the latest release of the National Land Cover Database (NLCD). More than just a map, NLCD is a stack of maps—a database. It has long been the…
Eyes on Earth Episode 125 – The LANDFIRE Program at 20

Eyes on Earth Episode 124 – Mapping Fires in Utah
In this episode of Eyes on Earth, we talk to forest ecologist Jim Lutz about the effort to map fires in Utah. Fire research in the West is dominated by the study of large fires, but the forests in…
Eyes on Earth Episode 123 – Bathymetry Mapping
This Eyes on Earth episode is the third in our series on using Landsat for coastal studies. We talk to physical geographer Jeff Danielson about bathymetry and how it is critical for coastal modeling.…
Eyes on Earth Episode 122 – EROS Interns, 2024
In this episode of Eyes on Earth, we talked with some of the interns who worked at EROS this summer. They shared their experiences learning about the cloud, AI, wildland fire research, terrestrial…
Eyes on Earth Episode 121 – Mapping the Australia Coastline
This episode of Eyes on Earth is the second in a series about how Landsat is helping researchers study coastal changes. The first one was about mapping changes to beaches in California and using…
Eyes on Earth Episode 120 – Mapping the California Coastline
In this episode of Eyes on Earth, we begin a series on Landsat’s usefulness in coastal studies. First, we talk with Sean Vitousek, a USGS research oceanographer, about changes to beaches in…
