Abstract
This paper explores the evolving drone technology by focusing on its diverse applications, challenges, and future potential. Drones, also known as Unmanned Aerial Vehicles (UAVs), have become essential across a variety of sectors. This ranges from military operations to civilian uses like agriculture, logistics, surveil- lance, and entertainment. The versatile nature of drones is apparent in their ability to perform advanced tasks such as inspection and tactical strikes in the military. Drones also support more casual applications which include photography, drone shows, and delivery services. The capabilities of next-generation drones have improved due to digital advancements in technologies such as remote sensing, wireless connectivity, and autonomous flight systems. UAVs are also being utilized for waste management, particularly in collecting data in solid waste landfills. In civil infrastructure, drones are playing a crucial role in real-time monitoring, disaster management, traffic detection, and infrastructure inspection which offers cost-effective and safer alternatives to other methods. UAVs also have applications in search and rescue operations, crop monitoring, security surveillance, and logistics. The primary strength of UAVs is their ability to capture bird’s-eye views which provides access to hard-to- reach places and produces valuable visual data for further analysis. In addition to these uses, UAVs are transforming fields such as cartography and archaeology by providing detailed aerial imagery that can be processed into ortho-mosaic photos, digital elevation models, topographic maps, and 3D models. These products facilitate mapping large areas and conducting archaeological surveys more efficiently. However, drones face several challenges which include privacy and security concerns, regulatory complexities, inadequate quality of on-drone surveillance equipment, and high operational costs.
