R-evolution, the green-technology subsidiary of Hexagon, has begun aerial 3D mapping flights in Brazil to support environmental reclamation in the mining sector. The project uses hybrid airborne imagery and LiDAR technology to create digital twins of natural habitats surrounding industrial assets.

The initiative, part of Hexagon’s Green Cubes programme, is being deployed by Vale, the world’s largest iron ore producer. The system maps areas at a resolution of 10 centimetres, producing high-density point clouds with more than 40 points per square metre. This data allows for detailed 3D modelling of forest structures, enabling mining companies to monitor biodiversity and rehabilitation progress.

At Vale’s Mina de Águas Claras site, the technology is being used to monitor a 1,908-hectare closed mine currently undergoing repurposing. Early monitoring using AI-enhanced camera and sound traps has already identified 146 bird species and the return of local predators. The new airborne flights will expand this monitoring to a 20-square-kilometre area.

“By embedding Green Cubes digital reality into the mining life cycle, we’re enabling our mining partners to accelerate restoration and improve compliance,” said Erik Josefsson, President of Hexagon’s R-evolution.

The project also includes a community engagement element where portions of the digital twin are recreated in the game Minecraft. This allows users to explore the reclaimed sites and learn about biodiversity. Hexagon confirmed that the Green Cubes solution is also being adopted by Samarco for similar reclamation efforts in other regions.
