The field of geomatics and land surveying is undergoing a profound transformation driven by the integration of Unmanned Aerial Vehicles (UAVs), or drones. Traditional surveying methods, while accurate, are often time-consuming, labor-intensive, and pose safety risks in challenging terrains. This paper explores the disruptive impact of drone technology, which offers a paradigm shift towards rapid, high-precision, and cost-effective data acquisition. By leveraging advanced sensors, including high-resolution RGB cameras, LiDAR, and multispectral imagers, drones generate dense 3D data point clouds, orthomosaics, and digital elevation models with centimeter-level accuracy. This paper outlines a comprehensive framework for drone-based surveying, detailing the workflow from mission planning and data capture to processing and analysis. The proposed system demonstrates significant advantages in applications such as topographic mapping, volumetric calculations, construction monitoring, and deformation monitoring. We conclude that drones are not merely a supplementary tool but a foundational technology that is reshaping the future of geomatics by enhancing data density, operational efficiency, and decision-making capabilities, thereby paving the way for the creation of dynamic, intelligent digital twins of the physical world.
