This is a handy tool to report the contents of the header, the VLRs, and a short summary of the min and max values of the points for LAS/LAZ files. The tool warns when there is a difference between the header information and the point content for counters and bounding box extent. When you send us a support request we will usually ask you to run something like

lasinfo -i lidar.laz -odix _info -otxt

and send us the resulting ‘lidar_info.txt’ file. This is also good practice when asking a question in the LAStools user forum. This tool is 100% open source LGPL. For more details see the README file.
