Hello, I can confirm you are not alone on this one. I am having the exact same issue. LAStools is working perfectly fine on its own, but when using the ONE (One-Step-Processing) tool I receive "Error: Algorithm LAStools: lasground not found". Let me know if you figure it out, I will do the same. Hopefully someone can help to figure this out soon. Cheers! :)

Hi and thanks for reporting this. Can you please provide which OS, Version of QGIS and Version of the other plugins (LAS Tools etc.) you are using?

stefaneichert avatar Dec 11 '23 07:12 stefaneichert

Thanks for the response. For me, I am using -> OS = Windows 11; QGIS Version = 3.32.3; Whitebox version = qgis plugin 1.0.9, binary download 2.3.0; LASTools version = qgis plugin 2.0.1, executables 2.0.2.

I looked into this and can confirm. The error is caused by new filenames in the Lastools binaries. They are now named e.g. lasground64 and no longer lasground. It will be fixed in the upcoming version of the LidarToolbox. In the meantime as a workaround you could install an older version of lastools (before they changed to 64bit)

There are some Issues with the new Version of Lastools as they renamed the algorithms and also the binaries are renamed (which mostly affects the linux version) and also some updates in GDAL that do no longer work with temporary files. It will take some time to implement this in a new version. For now, as a quick fix, you can try the attached .zip file and install it from zip in the Qgis plugin menu. Please be aware that this comes without any warranty and at your own risk. I tested it with QGIS 3.34.1-Prizren on Ubuntu 22.04 (but with Lastools running on wine) and the latest version of WBT, RVT etc. so it should work on windows machines and linux OS when using wine for Lastools. Once I implemented and tested this properly a new version will be available via the regular Plugin Repository of Qgis (probably in late January/February) open_lidar_tools.zip

"...you can try the attached .zip file and install it from zip in the Qgis plugin menu..." It works for me !

OpenLidarToolbox has just been updated to Version 2.3 and should now work with the current versions of QGIS and LAStools without issues.
