Episode 79 – Landsat Global Archive Consolidation

Sources/Usage: Public Domain. View Media Details

The Landsat archive at EROS contains an unparalleled 50 years of Earth observation data. But with earlier technologies, some Landsat scenes were collected and stored only by international ground receiving stations rather than in the central archive at EROS. More than 10 years ago, to help make that far-flung data available to scientists interested in land change over time, the Landsat Global Archive Consolidation (LGAC) project began having the reels and tapes sent to EROS to digitize that information. In this episode, we learn how that project has deepened the archive dramatically.

Episode 53 - Remapping Canada's Fire History

Sources/Usage: Public Domain. View Media Details

Mapping fire perimeters is important work. It guides post-fire restoration efforts, fire mitigation strategies, and helps track of trends in burn severity over time. In the past, many of Canada’s fire agencies relied heavily on techniques like sketch mapping, which estimate burned area without exact measurements. In the pre-satellite era, pilots would sometimes fly over the edge of a fire while a passenger recorded its extent. On this episode of Eyes on Earth, we hear about what two researchers from Natural Resources Canada learned when they used Landsat satellite data to rebuild historical fire perimeters.
