las2las_transform¶

Description¶

This tool uses las2las to filter LiDAR points based on different attributes and to write the surviving subset of points to a new LAZ or LAS file. For more info see the las2las page and its online README file.

Parameters¶

verbose [boolean]

Generates more textual control output to the console.

Default: False

Default: False

input LAS/LAZ file [file]

The file containing the points to be processed.
