How to Install LAStools Toolbox in QGIS

Posted on the 14 October 2014 by T_mackinnon @tedmackinnon

We had an ArcGIS LiDAR processing toolbox since April 2012 and now we have one for QGIS as well. It has been tested successfully with QGIS 1.8.0-Lisboa, 2.0.1-Dufour, 2.2.0-Valmiera, and 2.4.0-Chugiak. Download and install QGIS. For version 2.2.0-Valmiera and older follow all the steps. Do not delete or copy any files for the newest version 2.4.0-Chugiak but skip directly to step 4 and disregard most of step 6:

  1. If you already started QGIS then exit the application.
  2. Put the ".\lidar" folder that is inside this ZIP file into its place. This ZIP file only works for QGIS 2.2.0-Valmiera. For QGIS 2.0.1-Dufour you need to use the contents of this ZIP file instead. And for QGIS 1.8.0-Lisboa use this ZIP file and delete the folder "C:\Users\Martin\.qgis\python\plugins\sextante\lidar" instead.
  3. Get the most recent version of LAStools by downloading the 20 MB "lastools.zip" file.
  4. Drag and drop (or extract) the ".\lastools" folder from inside the 'lastools.zip' file such that there is no space in the path (e.g. bad: "C:\Program Files\lastools", good: "D:\software\lastools").
  5. Start QGIS. If there is a Python script error carefully repeat steps 1 to 3.
  6. Look at the file you just created by running lasview from the toolbox. Yay!

Kudos to Victor Olaya for creating this whole framework and providing me with example scripts for a simple LAStools toolbox that I just had to modify ... (-:
