The current paper aims at presenting multitemporal monitoring of two crop fields using
close-range aerial photogrammetric techniques with a combination of different sensors. A fixedwing
unmanned aerial vehicle was used to map the crops regularly in 2016 and 2017. The goal of
the following study is to show the experimental results of an enhanced keypoint number extraction
of NIR and TIR images and the importance of radiometric calibration of close-range data.
