The MAPIR Camera Reflectance Calibration Ground Target Package contains a series of 4 ground targets composed of a felt-like material that have known reflectance curves. Before commencing a survey all the Mapir cameras should capture an image of the entire target. This can then be used to help calibrate images captured in the image processing software.
We therefore highly recommend that you purchase the Mapir Camera Reflectance Calibration Target to complete your system.
