Digital mapping in mining refers to the creation, management, and application of spatially accurate, computer-generated maps of geological features, mining infrastructure, topography, and operational boundaries using digital technologies such as geographic information systems (GIS), LiDAR, drone photogrammetry, GPS, and remote sensing. In bauxite, gold, iron ore, and diamond mining, digital mapping has replaced traditional hand-drawn and paper-based surveying methods, enabling much faster, more accurate, and dynamically updatable spatial representations of the mining environment. Applications of digital mapping in mining include detailed geological mapping of mineralisation and ore body boundaries, pit and underground development surveys, structural geological mapping for geotechnical assessment, environmental baseline and impact mapping, haul road and infrastructure layout planning, and blast pattern design. Digital mapping data is typically stored in GIS databases and integrated with mine planning software to enable 3D visualisation and spatial analysis. Drone-based digital mapping using photogrammetry and LiDAR can generate high-resolution digital elevation models (DEMs) of pit floors, benches, and waste dumps in a fraction of the time required by traditional survey methods. Real-time digital mapping capabilities allow survey data to be updated continuously and shared instantly across technical teams, improving operational responsiveness and reducing the risk of mining errors caused by outdated spatial information.
