Abstract
This paper presents a novel algorithm for calculation of plant area density based on surface and volume convex hull which is applied to each horizontal cut of a point cloud data. This method can be used as an alternative to conventional voxelization approaches to improve accuracy and computation efficiency. The terrestrial data was collected from a boreal forest at Peace River, Alberta, Canada during summer and fall in 2014. This technique can be applied to an arbitrary point cloud data to calculate all other metrics of forests including plant area index, leaf area density, and also leaf area index.
