Unmanned Aerial Vehicles (UAVs), commonly known as drones, have transformed the way aerial operations are conducted across civilian and military domains. From aerial surveillance, mapping, and disaster management to precision agriculture and logistics, UAVs offer unmatched flexibility, speed, and cost efficiency. Advances in sensors, autonomy, and communication technologies are rapidly expanding their capabilities and applications. As regulations evolve and technologies mature, UAVs are set to become an integral part of modern airspace and digital infrastructure.
