The aim of this paper is to determine the benefit of modern methods of scanning and processing images of a rapeseed crop to determine affected areas at the end of winter. There are where the measurements took place is on the study grounds of “Belciugatele Research Station - Moara Domnească Farm”. Three methods were used, all based on the same image provided by a drone as a basemap, and RTK-GPS measurements. For the first method the affected areas were delimited using a RTK receiver, which required a person on the ground to manually provide the required data. The second method uses the same image, but digitizing was done at a later date by using GIS instruments. In the third method the digitizing was also done using software, by classifying the pixels. The result of the study showed that the third method was superior because of higher precision and lower processing time.
