The OneOak tree was scanned using state of the art scanning equipment before it was felled. This research has contributed to the OneOak tree being the most studied oak trees. The data will be used to accurately estimated the volume of the tree, and this in turn will be combined with the weight of the tree to estimate its carbon content and biomass.

The laser scanning research was supported by Treemetrics and the equipment and work was brought to the site by Leica Geosystems and scanning specialists SCCS; the foremost provider of innovative solutions in surveying, monitoring, setting out and mapping. SCCS were asked to complete a detailed laser-scanned survey of the OneOak tree and surrounding woodland.

The Leica C10 Laser Scanner was placed in various stations around the tree and in just over 6 minutes at each station the scanner had measured a complete 360 degree field of view. The scanner records close to 50,000 measurements per second that result in a point cloud.

The data collected has produced a digital record of the tree, including its exact position, volume and many of the required dimensions. The 3D model is accurate to within 2-3 mm.
