Unless you use extra bytes, the LAS format does not support this, as the data types are fixed.

 

If you use extra bytes, you can use the 'extra_dims' option to choose the type of the output dimension.

 

You should read the LAS specification for details.

Hi,

 

May I know how to change the data type of an attribute(or field) when exporting the las file.

 

For example, if the intensity is 2 byte integer, how do I square root the value and export as a 1 byte integer in a las file.

 

Please advise.

 

Thank you.

 

Best Regards,

 

Peter
