Abstract : Drones, also known as unmanned aerial vehicles (UAVs), have redefined the field of aerial surveying by offering high-resolution, low-cost, and real-time spatial data acquisition capabilities. This paper explores the evolving role of drones in geospatial data collection, particularly in topographical mapping, construction, disaster monitoring, and land-use planning. Traditional surveying methods, while accurate, often face limitations such as high costs, terrain accessibility, and longer data turnaround times. The integration of drone technology in surveying offers a viable alternative that addresses these constraints. With advancements in sensor technology, photogrammetry, LiDAR, and software-driven analytics, drones have transformed the precision and scope of aerial surveying. This paper presents an in-depth understanding of the key components, advantages, applications, and challenges involved in drone-based aerial surveying. It further discusses regulatory aspects, future trends, and the integration of Artificial Intelligence and GIS with drones to enhance data interpretation and decision-making processes. By mapping the technical, practical, and societal dimensions, this study emphasizes drones as indispensable tools in modern geospatial applications.
