The image shows trees reconstructed from points of light that come from laser beams known as “LiDAR” fired from an airplane. As the points reflect from the needles, branches and leaves of trees back to the airplane, First Resource Management Group can build a 3D “point cloud” with the height and location of each point, and thus of the leaves, needles and branches of the tree.
The results included detailed information about the height of hardwood and softwood trees including approximate age and volume. It’s information that can be used to calculate how much carbon is stored in the trees and the value of the timber. “Basically it shoots a very faint laser beam that you can't see. It kind of does a scan back and forth and shoots all these little points down at the earth and it hits the forest and it bounces back kind of like a radar does,” Green explained.That’s where SkyForest comes in. It can combine the LiDAR data with satellite imaging to map out hardwood and softwood - an important distinction for woodlot owners.
