The lascopy tool is well-known for matching data from different LAS/LAZ files and copying attributes between the files. The matching key is expected to have an identical timestamp/return to match the data. The redesign of lascopy expands the matching and coping part of the tool: it can now match not only for identical GPS time […]

Sometimes Windows refuses to start a program. This may be caused by Windows‘ internal security mechanism or by external virus scanners installed by users to protect their computers against viruses, malware programs, serious damage or theft of data. The Microsoft Windows operating system tries to prevent programs from randomly starting that appear suspicious, (e.g., if

One of the first LAStools features was to export LAS/LAZ to textfiles and import textfiles to LAS/LAZ (las2txt and txt2las). Typically, the format for parsing the textfile is specified in the “-parse” or “-oparse” argument. The parameters of this argument define which properties of a lidar point are exported or imported. With Version 240125, these

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 is not available right now on Linux.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
LAS and LAZ are both very common and powerful formats to save pointcloud data. Nevertheless, some users, or programs, may require another point data format. A common general format to save geometric data, for said requirement, is the wavefront OBJ format. Using one of the sample LAZ files of LAStools we will show you how

Install While QGIS is probably the most popular free open-source Geographic Information System (GIS) software widely used in the geospatial industry and education, LAStools is probably the fastest and most efficient point cloud data processing software for LiDAR datasets. Therefore, it is useful to bring these powerful software components together. Therefore, the QGIS community and

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
