Eyes on Earth is a podcast on remote sensing, Earth observation, land change and science, brought to you by the USGS Earth Resources Observation and Science (EROS) Center.
Eyes on Earth Episode 112 - Landsat in Popular Media
11/02/2024In this episode of Eyes on Earth, we aim to separate science fiction from science fact when it comes to how Landsat satellites and the EROS Center are portrayed in popular media. To do that, we consulted experts on a range of potential uses, including military, heat signatures, paleontology, and forests.
Eyes on Earth Episode 111 – Mendenhall Fellow’s Drought Forecasting
22/01/2024In this episode of Eyes on Earth, we spoke with Mikael Hiestand, a Mendenhall Postdoctoral Fellow. Using algorithms developed at EROS, Mikael is working on near-term drought forecasting. With synthetic Landsat data, he found that predicting evapotranspiration could be used as a means of drought prediction and monitoring. The Mendenhall Fellowship allows people who have just completed their PhD an opportunity to work on research with USGS scientists and prepare for their career.
Eyes on Earth Episode 110 – Geospatial Information Response Team
18/12/2023First responders need reliable, accurate mapping capabilities as quickly as possible in the wake of a disaster—and they don’t have time to download and organize it. In this episode of Eyes on Earth, we learn how the USGS Geospatial Information Response Team draws data from multiple sources to show what an area looked like before an event as well as after, creating accessible, usable maps and data sets for those bringing relief.
Eyes on Earth Episode 109 – Fall 2023 EROS Poster Session
04/12/2023In this episode of Eyes on Earth, we hear from several EROS staff members and university graduate students who took part in our Fall Poster Session. Lively conversations filled the EROS atrium during the hour-long event. Participants got to learn from one another as they shared their work. We talked to a few of them to get quick summaries of their research.
Eyes on Earth Episode 108 – Landsat 8’s 100th Drag Make-Up Maneuver
20/11/2023The Landsat Program is considered the gold standard for satellite Earth-observation imagery. To keep it that way, the USGS EROS Flight Operations Team continually monitors the flight paths of the Landsat satellites to make sure they stay at a consistent 705-kilometer altitude. That means frequently speeding it up to counter the effects of atmospheric drag. But that’s not all. The team accounts for solar activity, space junk, and other factors to keep the satellites safe. Landsat 8’s 100^th^ Drag Make-Up maneuver in October 2023 gives us the opportunity, in this episode of Eyes on Earth, to talk about these and the other maneuvers the flight team executes and how they work.
Eyes on Earth Episode 107 – EROS 50th: Land Cover, Part 2
13/11/2023The National Land Cover Database (NLCD) has a long history as the definitive U.S. land cover product. But the newer Land Change Monitoring, Assessment and Projection (LCMAP) effort takes a longer look back in time. In this episode of Eyes on Earth, we learn how the two projects at EROS, both based on 30-meter resolution Landsat satellite data, are merging to bring the strengths of each to future data releases under the NLCD name. This is the second of two episodes discussing land cover work at EROS, with the first focused on earlier pioneering efforts.
Eyes on Earth Episode 106 – EROS 50th: Land Cover, Part 1
30/10/2023Several decades ago, USGS EROS employees were pioneers in land cover mapping—turning satellite imagery into a record of what covers the land, from farmland to forest to urban areas. National and global datasets with a variety of uses resulted from these efforts. In this episode of Eyes on Earth, we explore some of this history, along with how it benefited people at the time and the mapping efforts that would follow. Our next episode will look at two modern efforts at EROS, NLCD and LCMAP, and how their strengths are merging for the next generation of land cover and change products.
Eyes on Earth Episode 105 – Imagery Challenges of Alaska
10/10/2023In this episode of Eyes on Earth, we focus on Alaska. Rich in wildlife and natural resources, not to mention its sheer size, Alaska has long been a source of fascination for remote sensing scientists. But it is also a source of frustration, with frequent cloud and snow cover and months of darkness each year. Three EROS researchers well versed in interpreting Landsat imagery from Alaska shared their insights about the Last Frontier.
Eyes on Earth Episode 104 – EROS 50th: Alumni and Friends, Part 2
25/09/2023At the USGS EROS 50th anniversary events on August 17-19, 2023, a special effort was made to include alumni who had worked at the center, especially those from the earliest years of EROS’ existence. This episode of Eyes on Earth is the second to highlight their stories, with emphasis on science, technology, and EROS’ international outlook.
Eyes on Earth Episode 103 - EROS 50th: Alumni and Friends, Part 1
18/09/2023At the USGS EROS 50th anniversary events on August 17-19, 2023, a special effort was made to include alumni who had worked at the center, especially those from the earliest years of EROS’ existence. This episode of Eyes on Earth highlights their stories, with emphasis on EROS’ history and its dedicated employees.
