Abstract
The use of remote sensing in the field of agriculture is very diverse. It includes detection of the amount of chlorophyll in crops, the amount of water, the detection of pests, the creation of maps for selective spraying and feeding, etc. In this work, different vegetation indices were applied on satellite imageries obtained from platforms: Sentinel2, Landsat8, RapidEye, and PlanetScope, in order to detect trends in the vegetation of different cultures. RapidEye and PlanetScope imageries were used in order to detect nitrogen variation for agricultural parcels in the area of the municipality of Becej. In this case indices NDVI, NDRE, and MSAVI2 are applied for cultures: corn, sunflower, wheat, sugar beet, and soybean. Sentinel2 and Landsat8 imageries were used for the analysis of the orchard near Celarevo in the municipality of Backa Palanka and analysis of agricultural parcel with a predominantly agricultural crop near Stapar in the municipality of Sombor. The detection of an area with health and non-health vegetation was made, as well as a comparison of the obtained vegetation trends between two platforms. The applied indices were: NDVI, TNDVI, GNDVI, EVI2, WDRVI, and GLI.
