In this episode, we talk with several people involved with the next Landsat mission, targeted for launch around 2030. While that may seem like a ways into the future, it takes a lot of work to prepare for such a big mission. In Part 2 of this two-part series on Landsat Next, we’ll hear about what needs to be done before launch to prepare the ground system, data processing and data calibration. Be sure to also listen to Part 1, where we talk about how different Landsat Next will be from previous Landsat missions, and what scientists are really looking forward to with this mission.

Guests: Brian Sauer, USGS Landsat Next Project Manager at EROS; Chris Engebretson, USGS Acting Ground System Manager for Landsat Next at EROS; Cody Anderson, USGS EROS Calibration and Validation Center of Excellence Project Manager

In this episode, we talk with several people involved with the next Landsat mission. In Part 1, we’ll hear about how different Landsat Next will be from previous Landsat missions and how its additional spectral bands, higher resolution, and 6-day revisit will benefit science and society. Addressing the needs of the Landsat user community was a high priority in developing the mission, so we talk about what scientists are really looking forward to with Landsat Next. The Part 2 episode shares details about technical preparations, such as the ground system and data processing and validation.

Terry Sohl helped develop the National Land Cover Database, NLCD, when he first arrived, and now he’s overseeing significant improvements to the widely used product. But that’s just one part of his new role. In this episode, Sohl provides an overview of the science efforts at EROS and how artificial intelligence and machine learning help scientists focus more on the work that helps society. He also shares his vision for the future.

First 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, 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.

Guests: Lance Clampitt and Alexandra Fredericks of the Geospatial Information Response Team

Episode 84 – Hurricane Disturbance Mapping

Sources/Usage: Public Domain. View Media Details

In this episode, we learn about the effort to map disturbances in Florida from Hurricane Ian in near real time. When disaster strikes, near-real-time images of its effects can be invaluable. In this episode, we learn about how a newly developed system using the Harmonized Landsat Sentinel-2 dataset and artificial intelligence was put to the test when Hurricane Ian tore through Florida in late September 2022. By comparing pre-storm and post-storm imagery, the system quickly flagged anomalies statewide such as brightness, which could indicate exposed sand or bare land after a hurricane. Harmonized Landsat Sentinel-2 data is available through the Land Processes Distributed Active Archive Center, or LP DAAC for short, located at EROS, which is also home to the entire Landsat archive.

In this episode, we get a rundown on the International Charter Space and Major Disasters. 

When a disaster like a hurricane, flood or major wildfire hits a remote part of the world, the International Charter Space and Natural Disasters springs into action. The Charter’s members collect and distribute satellite-derived data that documents the damage, as well as derived products like as fire perimeter or structural damage maps – all at no cost to national emergency management agencies. In this episode of Eyes on Earth, we learn about the Charter and EROS’ involvement on the occasion of the collaborative organization’s 20^th Anniversary.
