    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 EROS’s Landsat operations room and what the technicians do before, during, and after a Landsat pass. The task of making sure those bits of data make their way to the archive so it can be used for land change science occurs for them several times a day. As routine as it might be sometimes, they are a small but important part of a large mission that is documenting global land change.

    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. About 30 posters were on display in the EROS atrium from EROS staff and several students from South Dakota State University and the University of South Dakota. We talked to a few of them to get quick summaries of their research.

    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 Flight Center and engineers at EROS work together to collect imagery, send commands to the satellite, and keep it healthy. After over 133,000 orbits and 3.3 million images collected, Landsat 7 stopped acquiring imagery in 2024. We talked with some of the people who helped keep Landsat 7 flying to make sure it could keep doing its job during its long life. They talk about the close calls, different types of maneuvers, working on holidays, and creatively solving problems to keep it flying and operating. And as always, we discuss the importance of the Landsat mission, its global legacy, and the continuity of the long record that goes back to 1972.

    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 foundational land cover source for scientists, resource managers, and decision-makers across the United States, and now the next generation of USGS land cover mapping is here. This new release includes land cover data of the United States for every year back to 1985, so it is now called Annual NLCD.

    Eyes on Earth Episode 125 – The LANDFIRE Program at 20

    In this episode of Eyes on Earth, we talk about the Landscape Fire and Resource Management Planning Tools (LANDFIRE) project, which is commemorating its 20th year of providing geospatial data to support natural resource management and wildland fire planning. LANDFIRE brings a lot of data together, over 30 data products, into one place. The publicly available, consistent data maps disturbance to the landscape and vegetation condition, which can be useful to virtually any application that deals with what’s occurring on the landscape. LANDFIRE has now been doing this for 20 years, and we talk with some of the people who have been working on LANDFIRE that entire time.

    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 Utah are different. Utah typically does not have a lot of large fires as other western states do. So to better understand the differences that the specific Utah vegetation types have in their response to fire, a fire atlas for the state was developed. This data helps inform land managers about the implications for forest management and for prescribed fire planning.

    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. Bathymetry captures the shape of underwater topography, and satellite-derived bathymetry helps fill in areas where there are data gaps. Even though Landsat was designed to image land, it’s a big part of this work because of its systematic temporal coverage. Besides that, high-resolution data from sonar and lidar are too labor intensive to collect everywhere. Therefore, they use all these sources together to get a better picture of bathymetry, especially in remote areas. This modeling helps with studying changes to shorelines such as storm surge, sediment transport, and flood damage.

    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 lidar scanning, and more. The common theme among them was recognizing the value of the EROS mission and noticing the passion their co-workers demonstrated in their work. They also shared advice for future interns at EROS.
