At the USGS EROS Center, we study land change and produce land change data products used by researchers, resource managers, and policy makers across the nation and around the world. We also operate the Landsat satellite program with NASA, and maintain the largest civilian collection of images of the Earth’s land surface in existence, including tens of millions of satellite images.
Earlier scenes didn’t always make it into the central Landsat archive, instead sitting in storage at international ground receiving stations. This episode of our remote sensing podcast describes the process that has gradually added millions of those far-flung Landsat scenes to the 50-year archive for scientists to use in studying land change over time.
Major rifts have formed near a distinctive feature in Antarctica called the McDonald Ice Rumples. Landsat satellites have watched changes in the Brunt Ice Shelf there for nearly five decades.
