Abstract. This paper presents technical details about georeferenced orthophoto generation for precision agriculture with a dedicated selfconstructed camera system and a commercial micro UAV as carrier platform. The paper describes the camera system (VIS + NIR) in detail and focusses on three issues concerning the generation and processing of the aerial images related to: (i) camera exposure time; (ii) vignetting correction; (iii) orthophoto generation.
