of any changes to the landscape which could potentially cause harm to workers or force an expensive suspension of operations. This technology is now being harnessed at large-scale and complex projects including Mogalakwena in South Africa, the world’s largest open-pit platinum mine. The operator, AngloAmerican, invested in the SiteMonitorSV, which provides real-time reconciliations for stockpiles and volumes, to enable better forward planning. SiteMonitor has helped contribute to an increase in productivity at Mogalakwena by 33% over two years and helped to lower the lost-time injury-frequency rate from 0,68 in 2013 to 0,12 per 200 000 hours worked in 2014. 

capturing vast quantities of data while on the move. One of the key advantages of Mobile Laser Scanners (MLS), including multi- platform mapping systems such as ROBIN, is that they can generate full digital surface models in a single set up. In environments that are deemed unsafe or remote, they can be mounted to automated vehicles such as trucks, trolleys or UAVs (Unmanned Aerial Vehicles) to gather data. It also speeds up operations significantly as data is collected around 80 per cent faster than it would be if a terrestrial scanner or total station were used. From this, operators can make decisions about how machinery and vehicles should be safely deployed to site, as well as take note
