Tools for lidar simulation and lidar processing
The slidaRtools package provides a couple of useful functions to simulate and process lidar data of forests. Lidar simulation means to create discrete lidar point clouds or large footprint waveforms for a given tree list using their positions, crown properties and a Beer-Lambert light extinction approach. Lidar data processing means operations like point cloud thinning, conversions between XYZ-tables, rasters, matrices and arrays, spatial indexing, vertical profile delineation, etc.
A demo script can be found inside the folder DemoWorkflow, along with a small example dataset.
