Orléans' underground tunnels: 3D for risk prevention
Could 3D imaging protect people from cavity collapses - and show us what lies under our feet? The new 3D digital technologies aren't just used for printing and gaming: they can also help to prevent risks such as underground cavity collapses, which can cause sinkholes to form in city streets and even cause houses to collapse. Explore the underside of Orléans and the 700-odd underground caves and quarries brought to light by the new Zeb-revo tool.
