This is a quick guide on how to use point cloud (.las) files with QGIS.

First you need to find your data. In my case I found it from the national map:

I also found higher resolution lidar for the state of oregon from

LASTools

These are a set of tools you'll need to visualise point clouds.

Download the tools from here:

https://rapidlasso.com/lastools/

Extract the zip folder and place in a filepath with no spaces such as C:/LASTools

Open QGIS and go to:

Processing >> Options >> Providers >> Tools for Lidar Data >> activate

You can set your folder to the LASTools folder. It may give you an MSYS folder error, but that just means you need to blank out the default grass msys folder then it will go away.

Usage:

• laszip: zip/unzip laz/las files
• lasground: get bare earth dem
