USGS employee Joe Adams positions a UAS over a calibration panel to capture a multispectral image with the attached MicaSense Dual multispectral sensor. This calibration image will be used to post-process the imagery in support of radiometric calibration research conducted at the Denver Federal Center in Colorado.

USGS researcher Victoria Scholl (NUSO) checks the image quality of photos captured using the Mavic Pro UAS over a bog in Alaska. These photos will be used to generate a Structure from Motion photogrammetry orthomosaic.

Victoria Scholl (NUSO), Kristen Manies (GMEG Science Center), and Joe Adams (NUSO) hiked the UAS gear through the woods and across a network of boardwalks to access the bog site at the BNZ LTER.

High altitude lakes provide opportunities to examine interactions between fires, drought and human activity across decadal to millennial timescales. The locations of these lakes near tree line make them more susceptible to climate-related changes in vegetation and associated biomass burning.
