I've looked up pdal documentation on how to clip LAS point cloud files:- https://pdal.io/workshop/exercises/analysis/clipping/clipping.html
Referencing this example, and having a quick look around, it seems like there only is an option for one output file. Please correct me if I'm wrong.
I am after the input LAS files being split into four separate output LAS files (following the geometries of the indextile shapefile).
I was able to achieve this with the LASTools command lasclip.exe, however I've reached the limit of the 'unlicenced' version of lasclip:-
lasclip -i C:/a/test/BY17_1401merged_test.las -split -poly C:/a/cropped_topo50.shp -o newfile.las
In the stdout for the above command; WARNING: unlicensed. over 3 million points. output slightly distorted. tiny xyz noise. points permuted. intensity, gps_time, user_data and point_source_ID zeroed. In the lasinfo report for one of the output LAS files. WARNING: real max x larger than header max x by 0.020000 WARNING: real min x smaller than header min x by 0.020000 WARNING: real max y larger than header max y by 0.020000 WARNING: real min y smaller than header min y by 0.020000 WARNING: real min z smaller than header min z by 0.010000
Is there any other way of splitting a LAS file into multiple output files using shapefile geometries? I have a Global Mapper license but cannot find a way to do it with this software. Unfortunately I was unable to get SAGA to work on my laptop and Whitebox is almost unusable (very slow) on my ubuntu computer.
