Data in Harmony: NASA’s Harmonized Landsat and Sentinel-2 Project
NASA’s Harmonized Landsat and Sentinel-2 (HLS) project is a groundbreaking initiative that combines data from Landsats 8 & 9 with the European Space Agency’s Sentinel-2A & 2B satellites.

ExtraDimensional—The Fusion of Landsat & GEDI
When Landsat’s vast decades-long archive is combined with data from other instruments it can provide amazing insight into how our world is evolving with us and around us. Here are some of the ways Landsat and GEDI data are being harnessed to help us better understand the complex relationship between humanity and nature.
