Abstract
The aim of the research is to precisely define the sample areas of the 3-year cover crop experiment planned in the Eger wine region. For the experiment it is necessary to delineate plots and plot sections with both nearly homogeneous and heterogeneous characteristics. For this purpose, five vineyard plots were first selected and their spatial heterogeneity was investigated. The plots were surveyed with real-time and multispectral sensors from low altitude on a drone platform. The resulting orthophotos, topography models and multispectral mosaics were used to zone and delineate the experimental vineyard rows. The GNDVI index, which is sensitive to both chlorophyll content and water volume, was used to establish the zones.
