If you need older versions or just parts of LAStools, visit the repository


Download the latest version. Unzip the files to a directory on your local hard drive. Then place your license file in the ./bin directory.


All version numbers follow the syntax: Year[YY]Month[MM]Day[DD] of release. Example: Version 211206 means the version was released on December 6, 2021. You may not necessarily need the latest version. If your version does what you want, everything is fine. Updates & bug fixes are listed in the changelog .

Version check: On Windows, run one of the executable files such as “ladatum.exe”. The GUI shows the version number at the bottom left. On the command line, type the name of the executable followed by -h.

If you encounter problems processing lidar, please follow these steps:

  1. Check your (raw) data. Use lasvalidate to check whether your input data is valid.
  2. Download the latest version. If the issue is new in this version: Try an older version. It may make sense to run different versions in different directories. Run lascopy -h to check your version number. Run all tools with the -v (verbose) option to see if they already generate a warning.
  3. Extract your problem. Break it down. This may already solve the problem.
  4. See if others had the same problem. Visit the LAStools User Group and use the search function with various keywords.
  5. Post your problem to the LAStools User Group. Focus on the problem. Break it down. Provide simple sample data so anyone can reproduce your problem. List the commands you ran. What did they output? What did you expect? Report the environment & version number you are using.
