SAGA-GIS Tool Library Documentation (v8.4.1)

Tool Export LAS/LAZ File

The tool allows one to export a point cloud as ASPRS LAS (or compressed LAZ) file using the "Point Data Abstraction Library" (PDAL).
The file extension of the output file determines whether the file is written compressed (*.laz) or uncompressed (*.las).
The number and type of attributes that can be exported depends on the chosen LAS file version and point data record format. Please have a look at the ASPRS LAS specification on how these formats are defined.

PDAL Version:2.0.1 (git-version: Release)
