Tutorials and other materials are available at the Rapidlasso webpage.Ĭreating a DEM with LAStools can be done in two steps, first one to classify the point cloud into ground and no ground points and then calculating a DEM using only the ground points. If you want to know further details on how the LAStools work, you can read the README text files about each of the tools, in the C:\lastools\bin\ folder.
The path to the lastools folder cannot have spaces or special characters. Get the newest lastools version here and extract the content of the lastools.zip file into a folder in your system, for example, c:\lastools\.
Now you need to install the LAStools to your computer.
This is valid for some installations of QGIS 2.2 and 2.4.
