Tropical rainforests are volumetric and the full extent can only be measured using 3D-measuring technology. We scan the forest using a technology called LiDAR ( Light Detection and Ranging) and our laser sensors measure the forest at 3 cm accuracy.

To measure at scale we mount advanced LEICA Geosystems scanners to fixed-wing aircraft, which are then flown 2km above the forest canopy. The scanners capture laser photons beamed at 2 million photons per second. The data collected is then processed and turned into a three-dimensional grid. Each cubic meter in the forest grid is uniquely visualised and we use this unit as a baseline to add the next tier of data as the forest develops.
