Geological Earth Mapping Experiment

The Campaign

The Geological Earth Mapping Experiment (GEMx) is a joint campaign between NASA and the United States Geological Survey (USGS). The goal of GEMx is to map critical minerals using airborne hyperspectral imagery and to study their impact on climate. Currently, GEMx has had three deployments over the southwestern United States during the boreal spring, summer, and fall of 2023-2024. Hyperspectral imagery was collected using 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 will support the development of the NASA Surface Biology and Geology (SBG) mission.
