The Campaign
The Geological Earth Mapping Experiment (GEMx) is a joint project between NASA and the United States Geological Survey (USGS) to map critical minerals using airborne hyperspectral imagery and study their impact on climate. So far, GEMx has carried out four deployments over the southwestern United States during spring, summer, and fall of 2023-2025. Hyperspectral data was collected with remote sensors such as the MODIS/ASTER Airborne Simulator (MASTER), Airborne Visible/Infrared Imaging Spectrometer (AVIRIS), and Hyperspectral Thermal Emission Spectrometer (HyTES). GEMx is funded through the USGS Earth Mapping Resources Initiative (Earth MRI) and aims to support the development of NASA’s Surface Biology and Geology (SBG) mission.
