SAGA-GIS Module Library Documentation (v2.1.3)

Module Export LAS Files

This module exports a SAGA Point Cloud as ASPRS LAS file (version 1.2) using the "libLAS" library. It allows to write Point Data Record Formats 1 to 4. Please have a look at the ASPRS LAS 1.2 Format Specification for more information on the attributes supported with each format.
Get more information about the "libLAS" library at http://liblas.org
Please note, that the liblas writer does an "isValid()" check on each point. This might cause problems with MLS data because of the included scan angle check. MLS data ususally includes larger scan angles than ALS data and thus points may fail the test. Please always have a look at the summary printed in the message window.


liblas version: 1.2.1
