The LAStools Software Suite is a collection of 52 highly efficient, batch-scriptable, multicore command-line tools for processing point clouds. The tools can also be run via a native GUI (laslook) and are available as toolboxes (QGIS, ArcGIS Pro, FME, Erdas). The software combines robust algorithms with efficient I/O, making LAStools the fastest & most memory-efficient solution for batch-scripted multicore LiDAR processing. It can turn billions of points into valuable products at blazing speed & with low memory requirements. The ability to script the modules makes the software ideal for use on web servers or in the cloud. LAStools has deep market-penetration and is widely used across industry, governments, research labs & educational institutions around the globe.

Overview of all LAStools

DATA CONVERSION (Import / Export)

Converts binary LAS or LAZ files to human-readable ASCII text format.
