UAV for Precision Agriculture in Vineyards: A Case Study in Calabria

It is well known that nowadays remote sensing has a very crucial role in agricultural applications using in particular spectral indices as analysis tools useful to describe the temporal and spatial variability of crops, derived from processing of satellite images, each with different resolutions on the ground, according to the satellite of origin. It is also known that today such information can also be obtained through the use of sensors mounted on UAV (Unmanned Aerial Vehicle). In the present note we want to carry out a detailed analysis to define the condition of vigor of a vineyard situated in the province of Reggio Calabria (Southern Italy), comparing multispectral satellite images (Sentinel-2) with those provided by UAV platforms at low altitude, using as a parameter of effectiveness the relationship between the NDVI (Normalized Difference Vegetation Index) and the vigor of the crops. It is also proposed a GIS (Geographic Information System) for the management of agricultural land in order to build a system that can provide alerts in case interventions are needed depending on crop water stress.
