WebAll LAStools read, process, and write the compressed format directly without having to first decompress the file. Our easy-to-use, ultra-light-weight, very efficient C++ programming API called LASlib (with LASzip-DLL) makes it easy to add read/write support of compressed LAZ files to your software. Support: See rapidlasso support Download: WebAnother way of reading point clouds in the LAS/LAZ in Python. Examples Directly read and write las import pylas las = pylas. read ( 'filename.las' ) las. points = las. points [ las. classification == 2 ] las. write ( 'ground.laz') Open data to inspect header (opening only reads the header and vlrs)
