All licensed tools can be tested for free without a license. Just download the full package with or without GUI and run LAStools with the „-demo“ argument. For quality tests, use small samples up to 1.5 million points. For performance tests, use point clouds of any size. Output distortions (e.g., noise, diagonal lines) are related […]

lasinfo is a well-known LAStool for examining LAS and LAZ files and is often used to output information from point cloud files. The output format has always been simple ASCII text. Quite a few users parse this text to extract information for further automated processing. This is possible but carries the risk of misinterpretation of

We are pleased to announce that PROJ has been integrated into LAStools, enhancing the capabilities of geodesic calculations, cartographic projections, and coordinate transformations in LAStools. PROJ is a generic coordinate transformation software that transforms geospatial coordinates from one coordinate reference system (CRS) to another, including cartographic projections as well as geodetic transformations. It is used

Release note for version 240510: The redesign of the error handling may require customization of scripts using LAStools. Background: The reasons for error messages can be minor (e.g. a tool argument is not in the correct range). However, especially when working in batch mode, it is crucial that errors in the process are reliably detected

In general, the z coordinate of a LiDAR point within a LAS/LAZ file contains the absolute z value of the coordinate system used. For some operations such as classification (lasclassify) or canope metrics (lascanope) it is mandatory to specify the “height above ground” as an additional value for the calculations. There have been several ways

The LAStools filter module was already able to filter colors according to RGB values. However, it sometimes makes sense to filter not only for RGB, but also for hue, saturation, and brightness values. Therefore, the HSL and HSV color models are quite common. LAStools now support these color models in filtering points. These are the

LAStools runs on Windows and Linux. This article describes the features and installation of LAStools for Linux. Features All binaries are 64bit.Multicore (-cores) is supported.BLAST (blast2dem) is available.The „-gui“ option is not available because most users run LAStools@Linux on the command line for batch processing. Installation Download the binaries via a browser or use the
This article is obsolete now. Please see the new article about „LAStools@linux“. LAStools@linux multicore is now available as a beta version. The data quality is checked against the current version of LAStools – we assume that the data is valid. Some arguments don´t currently work with Linux multicore, so this beta/test version was released for

As an input take, for example, a LAS/LAZ/TXT file and a SHP/TXT file with oneor many polylines (e.g. powerlines).This feature modifies points within a certain distance of those polylines.There are two separate options for running point selection; you can either: Affected points can be classified, clipped, or flaged. The input SHP/TXT file must contain clean
The new GUI wrapper for LAStools, „laslook“, is now available for download. Documentation For a quick startup guide we recommend the laslook introduction video. If you can’t view the video in your browser you watch the youtube version. Installation The installation is carried out via a setup programme.After the installation, only the path to LAStools

So far, LAStools could already read PTX files. These contain a small header including a rotation/transformation matrix. LAStools read the matrix and stored it in a VLR of the LAS/LAZ result – but without using the header. Now, LAStools supports PTX import and is able to convert the data through the PTX header matrix. We
