USGS researchers calibrate the compass of a multispectral payload mounted on a UAS prior to a flight in South Dakota

USGS researchers Lance Brady and Joe Adams (NUSO) calibrate the compass of an AgEagle/MicaSense multispectral payload mounted on a UAS prior to a flight in South Dakota. This involves lifting and rotating the aircraft in specific sequences as indicated on the connected tablet.

In support of radiometric calibration and validation research at USGS, the NUSO in July 2023 collected multispectral and hyperspectral UAS data at several sites near the Earth Resources Observation and Science (EROS) Center in Sioux Falls, South Dakota.
