Fuente: Wipo "precision agriculture" The present invention discloses a method for precision agriculture executed by an unmanned aeial vehicle (1) and a server (2) having at least one module for controlling operation of the unmanned aerial vehicle (1), the method comprising the steps of stitching, by a mapping module (21), a plurality of geo-tagged images to generate a map of an area to be travelled by the unmanned aerial vehicle (l); identifying, by an identification module (22), at least one geo-tagged target from the generated map, where each geo-tagged target is tagged with a reference point based on a height data relative to the ground plane; and generating, by a path planning module (23), a flight pathway for the unmanned aerial vehicle (l) to travel along and towards the geo-tagged targets over the area for discharge of pesticide; wherein the unmanned aerial vehicle (1) discharges pesticide at a targeted spot therebeneath when the unmanned aerial vehicle (l) arrives at the reference point above the geo-tagged target.
