CALIBRATED REFLECTANCE PANEL 2 (CRP2)

The Calibrated Reflectance Panel (CRP2) is a compact on the ground radiometric calibration tool. The panel has pre-measured reflectance values across the visible and near-infrared light spectrum and therefore acts as a “control”. Taking a picture of the calibration panel allows you to assign the known reflectance values and adjust your dataset accordingly during post-processing. As a best practice, CRP images should be captured before and after each flight to provide an accurate representation of light conditions during the flight.
