We are pleased to announce the implementation of 3D thinning in LAStools. The new tool lasthin3d has been added to the suite with version 250710:
- a fast 3d LiDAR thinning algorithm for point cloud data
- the data is thinned by placing a 3d-grid over the data points and taking only one point for each cell
- the grid size can be specified by x,y and z dimensions and the desired target point per voxel can be determined via arguments
- it is possible to select the point closest to the center, the highest, the lowest, a random point, or the point with highest or lowest intensity, return number or attribute value
Please see the README file for examples and more details about this tool.
