Hi all,

We are pleased to announce the implementation of 3D thinning in LAStools. The new tool is called *lasthin3d*. It will be released with the next version. A first version is already available for download:

Windows: https://downloads.rapidlasso.de/beta/lasthin3d64.zip
Linux: https://downloads.rapidlasso.de/beta/lasthin3d64.tar.gz

*lasthin3d* thins in horizontal and vertical dimensions. Thanks to an optimized algorithm, even very large point clouds can be processed. The target voxel size can be specified. 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 or a random point within a target 3d voxel.

>>>Please also note the important information in the attached readme file<<<

We appreciate your feedback.

Thank you for using LAStools!

Cheers, Silke

Hi Silke,

 

Great to see the addition of the lasthin3d tool to our kit.

 

A data thinning approach used in forestry, working with high density terrestrial scanning point clouds (TLS, PLS), is to pick the point with highest intensity in the voxel. Could this option be provided please?

 

Regards,

Hi Jan,

thank you for your feedback and the suggestion! 
It should be no problem to add the option to pick the point with highest intensity in the voxel
We will implement this in the next days / asap.

Cheers,
Silke
