Uncrewed aircraft systems (UAS) instrument validation and calibration

Detailed Description

Drone-captured photo of a vegetated field in Golden, Colorado. Faint paths visible across the grass formed from the consistent, repeated pattern walked by a spectrometer operator multiple times per day for multiple days in a row. Reference materials for radiometric calibration and validation of remote sensing imagery were placed along the edge of the field, seen on the right side of the image.
