Reflectance Calibration with Phantom 4M Multispectral data

There was some confusion in the past on how to process the Phantom 4M Multispectral data to “reflectance” level. Here a short summary for Agisoft Metashape 1.7.2 with a 50% reflectance panel from Micasense. In general: the P4M sun illu. sensor works for normalizing the within flight campaign variations while the panel reflectance measurement is […]
