POSSIBILITIES OF USING SENTINEL-2 SATELLITE DATA TO ESTIMATE CROP COVER AND LAI OF WINTER WHEAT AT DIFFERENT STAGES OF DEVELOPMENT

The study was conducted on a test plot located in the Yasnogorodsky district of the Tula Region; With a camera with fisheye lens photographs were taken at different points of the plot, each point with a geographical reference. Subsequently, the possible relationship between the information extracted from the classification of the photographs using the CAN-EYE software (LAI, percentage of vegetation) and the vegetatition indices (Ratio, NDVI, SAVI and EVI) calculated with spectral values obtained from the different channels of Sentinel-2 (B2, B3, B4, B5, B6, B7, B8, B8a) were evaluated. Finally, best regression models obtained for each phase of the winter wheat developmnet were used to create the maps of LAI and percentage of vegetation. According to our results, Sentinel-2 can be successfuly used to map LAI in the studied region at the shooting stage of winter wheat development with accuracy of 85 %. At other stages and for percantage of vegetation the accuracy of the models was below 50 %.
