A USGS remote pilot secures a gamma ray spectrometer sensor onto an uncrewed aircraft system (UAS) at the Grand Junction Regional Airport (GJT) in Grand Junction, CO. Concrete pads built into the tarmac at GJT contain known concentrations of naturally occurring radioactive materials including Potassium, Thorium, and Uranium for radiometric calibration.

This map of the United States and its territories shows geographic extent of the first-ever nationally consistent hydrography data acquired from high-resolution 3D Elevation Program (3DEP) data. FY26 projects are the result of ongoing Federal coordination via the 3DHP Working Group and the Alaska Mapping Initiative.
