Problem Description

When I try and attach a LAS Point Cloud image I am getting the message “Convert failed”

If LAS Point Cloud image is version 1.4 it is currently not supported. Defect 648818: has been filed to add support for LAS 1.4 Point Cloud images.

The attached steps can be used to determine LAS image version and convert LAS 1.4 Point Cloud image to LAS 1.2 Point Cloud image.

LAStools will need to be downloaded from:

Once the LAStools have been downloaded the following steps can be done.

Start > CMD

Right click CMD and select Run as administrator

In Command Prompt window

CD to the location on disk where the las2las.exe and lasinfo files are located

To determine LAS version

lasinfo -i LAS_14.las

Version shows in listing as "version major.minor"

To Convert LAS file from Version 1.4 to Version 1.2

las2las -i Disk:\Input_File_Location\LAS_14.las -set_version 1.2 -o Disk:\Output_File_Location\LAS_12.las

Example:

CD C:\Downloads\LAStools\bin

las2las -i C:\LAS_Files\LAS_14.las -set_version 1.2 -o C:\LAS_Files\LAS_12.las
