Cartography of edaphic variability from RPAS (drones). The present project aims to study the use of Remote Sensors on board of aerial robots (drones) with respect to the First Phase of the Precision Agriculture cycle. The final goal of the project specifically points to the establishment of correlations between the biophysical parameters that can be surveyed by multispectral cameras, and the eco-physiological conditions of the crops. Following the cannons of efficiency and sustainability a different Coverage Path Algorithms are going to be analysed in order to offer a further possibility to develop and implement them on an agricultural machinery and make it independent from humans manual control.
