UAV (Unmanned Aerial Vehicle) mapping, also known as drone surveying or photogrammetric mapping, refers to the use of remotely piloted aircraft equipped with cameras, LiDAR sensors, or multispectral sensors to acquire aerial imagery and data that is processed into high-resolution digital surface models, orthomosaics, point clouds, and topographic maps for use in mining planning and operations. In bauxite, gold, iron ore, and diamond mining, UAV mapping has rapidly become an indispensable tool for improving the speed, accuracy, and cost-effectiveness of survey activities across all stages of the mine life cycle. During exploration, UAVs enable detailed geological mapping of large, remote, or difficult-to-access areas, capturing structural features, alteration zones, and geomorphological indicators that would be time-consuming and expensive to document on the ground. In active mining operations, UAV surveys are used for regular volumetric calculations of stockpiles and waste dumps, pit and bench surveys for reconciliation with mine plans, and monitoring of slope movements and geotechnical instability. In iron ore and bauxite mines, which often cover vast areas, UAV mapping significantly reduces the time and cost of topographic surveys compared to traditional ground-based methods. For diamond mining, UAVs are used to map alluvial terrace systems, gravel deposits, and coastal marine environments targeted for diamond prospecting. UAV mapping data is integrated with mine planning software, geographical information systems (GIS), and resource models to support decision-making at all levels of the mining organization.
